═══ 1. Printer Properties ═══ Printer Properties The Printer Properties dialog contains a notebook of settings that describe your printer and its capabilities. Printer Properties are different from Job Properties which are more commonly modified for print jobs. Click on one of the following page names to get detailed information about settings available on that page: ■ Connections ■ Trays ■ Paper Sizes The Printer Properties dialog also contains buttons. Click on the name of a button to find out what it does. ■ Save ■ Cancel ■ Default Job Properties ■ Help Note: Some notebook pages will not appear on printer models that do not support any features from that page. All Printer Properties notebook settings are initially set to show the base characteristics of the printer as shipped from the manufacturer. Users typically only use Printer Properties when they have physically added things to their printer (e.g. additional memory, paper trays, paper sizes, etc.). It is important to keep Printer Property information as accurate as possible to ensure the printer driver creates the fastest, highest quality printouts. Warning! Users should be aware that changing Printer Properties from one Print Queue (or application) changes them for all other Print Queues. This is because each physical printer only needs one set of Printer Properties to describe it. Although, you can access the same set of Printer Properties for that printer from any Print Queue where you see it. Note: The Omni Printer Driver is a 32-bit IBM OS/2 Printer Driver requiring OS/2 Warp or greater to run. ═══ 1.1. Save ═══ Save Pressing the save button causes the Printer Properties dialog to close and all changes made to Printer Properties notebook pages are saved. The printer driver will now use these newly saved Printer Properties whenever printing to this particular printer. "Saving" changes the Printer Properties for all Print Queues on the desktop that reference that same printer. Note: If you do not wish to save or alter the current set of Printer Properties, but just want to close the Printer Properties dialog, simply press the Cancel button instead. ═══ 1.2. Cancel ═══ Cancel Pressing the cancel button causes the Printer Properties dialog to close. Any changes made to Printer Properties notebook pages are ignored by the calling application. The printer driver for that printer will still use the Printer Properties shown before any changes were made. Note: If you do want to save or alter the current set of Printer Properties, simply press the Save button instead. ═══ 1.3. Default Job Properties ═══ Default Job Properties Pressing this button brings up the Job Properties notebook. This is where you can set a unique set of Job Properties to apply to print jobs submitted that do not have any. Note: These Job Properties are rarely used since most applications supply them or the OS/2 spooler supplies them from Job Properties for the print queue. This button may be phased-out in the future since there are so few cases where these Job Properties are used. However, if you can not seem to get Job Properties to work when printing from your application these may be the correct ones to modify. ═══ 1.4. Help ═══ Help Pressing the Help button brings up this help window and shows the main help for the Printer Properties dialog. Once in the main help dialog, you can access help topics for any specific printer property shown anywhere in the Printer Properties notebook. ═══ 2. Connections Page ═══ Connections Page This page is used manage Form Connections for your printer. A Form Connection is a combination of a Tray, a Paper Size, and a Media Type. Some devices allow you to add and delete Form Connections. When this feature is available, the "Add" and "Delete" buttons will be enabled. See below for instructions. This page contains the following printer properties: ■ Defined Form Connections ■ Current Attributes ■ Trays ■ Paper Sizes ■ Media Types This page contains the following buttons: ■ Add ■ Delete Note: The Add, Delete, and Modify buttons will be available only if the printer supports user-defined Form Connections. Adding a New Form Connection: Simply select a Tray, Paper Size and Media Type from the lists within the "Current Attributes" area and press the "Add" button. A new connection with the attributes you selected is added to the "Defined Form Connections" list and can now be selected from Job Properties. Deleting a New Form Connection: Simply select a Form Connection from the "Defined Form Connections" list and press the "Delete" button. That Form Connection will be removed from the list and no longer displayed in Job Properties. Form Connection Usages: The printer driver uses Form Connection information to determine whether or not to allow a print job to be printed. If you print to a paper size that does not have a Form Connection you will get a "Forms Mismatch" error. Note: For a more detailed example of a Form Connection's usages see Form Connections. ═══ 2.1. Defined Form Connections ═══ Defined Form Connections This pulldown list allows you to view and select all Form Connections currently defined for your printer. When a Form Connection is selected, its component parts (Tray, Paper Size, and Media Type) are shown in the "Current Attributes" area.

Once a new Connection is added it is displayed in the "Defined Form Connections" list for selection. ═══ 2.7. Delete ═══ Delete Used to delete the currently selected user-defined Connections from the "Defined Form Connections" list. ═══ 3. Trays Page ═══ Trays Page This page is where you can view defined Paper Trays for your printer and their attributes. Some printers will also let you define new trays that than can be selected when defining Form Connections to print to. This page contains the following printer properties: ■ Defined Trays ■ Current Attribites ■ Name ■ Command ■ Feed Type ■ Automatic ■ Manual This page contains the following buttons: ■ Add ■ Delete ■ Modify Note: The Add, Delete, and Modify buttons will be available only if the printer supports user-defined Trays. ═══ 3.1. Defined Trays ═══ Defined Trays This pulldown list allows you to view and select all paper Trays currently defined for your printer. When a Tray is selected from this list, its attributes are diplayed below it in the Current Attribites area. The type of tray definition, either "built-in" or "user-defined" will also be displayed in that attribute area. ═══ 3.2. Current Attributes ═══ Current Attributes This group contains settings that show the attributes of the currently selected tray in the "Defined Trays" list on the same page. The following attributes are shown. ■ Name ■ Command ■ Feed Type The type of tray definition, either "built-in" or "user-defined" will also be displayed in that attribute area. ═══ 3.3. Name ═══ Name Displays the name of tray currently selected in the "Defined Trays" list. For printers that allow you to add new trays to the "Defined Trays" list, this is where you would enter the new name of the tray you wish to add. ═══ 3.4. Command ═══ Command This field shows hex command that will be sent to the printer to select the tray highlited in the "Defined Trays" list. Note: Any control character can be typed in as part of the command that needs to be sent to the printer. Simply enter all control or character codes in their Hex equivalent form. For example: The ASCII letter 'A' would be entered as its hex equivalent '41' and the ASCII number '5' would be entered as its hex equivalent '35'. This allows you to enter printer commands that contain control characters that do not always have an ASCII character that can be typed in from a keyboard. ═══ 3.5. Feed Type ═══ Feed Type This group contains all the methods by which paper can be fed from a paper tray to the printer. Only one of the feed types can be checked for any one paper tray. The following feed types are available. ■ Automatic ■ Manual ═══ 3.6. Manual ═══ Manual This option is checked when the current tray requires some manual intervention to feed the paper into the printer. When printing to a "Manual Feed" tray the user will be prompted with a dialog before each print job to insert a piece of paper. ═══ 3.7. Automatic ═══ Automatic This option is checked when the selected paper tray needs no manual intervention to feed paper. This means that the tray can feed individual sheets from a large stack of sheets in the tray without any help. No dialog is displayed before print jobs to ask you to load paper. ═══ 3.8.

Modify ═══ Modify Used to modify the currently selected user-defined Paper Size from information currently displayed in the Current Attributes area of this page. ═══ 5. Job Properties ═══ Job Properties The Job Properties dialog contains a notebook of settings that control how your printouts are formatted. Click on one of the following page names to get detailed information about settings available on that page: ■ Common ■ Monochrome ■ Color ■ HSV The Job Properties dialog also contains buttons. Click on the name of a button to find out what it does. ■ Save ■ Cancel ■ Help Note: Some notebook pages will not appear on printer models that do not support any features from that page. e.g. The "Color" page will only appear for color-capable printers. Photo-Quality Printing All Job Properties notebook settings are initially set for the optimal balance between quality and performance for each printer model. For printing photo-quality images and graphics you may wish to change the following job properties to achieve the best results: ■ Print Quality ■ Print Mode ■ Color Dither ═══ 5.1. Save ═══ Save Pressing the save button causes the Job Properties dialog to close and all changes made to Job Properties notebook pages are saved for the calling application. Printouts from that application will now use the newly saved set of Job Properties. Note: If you do not wish to save or alter the current set of Job Properties, but just want to close the Job Properties dialog, simply press the Cancel button instead. ═══ 5.2. Cancel ═══ Cancel Pressing the cancel button causes the Job Properties dialog to close. Any changes made to Job Properties notebook pages are ignored by the calling application. Printouts from that application will still use the Job Properties shown before any changes were made. Note: If you do want to save or alter the current set of Job Properties, simply press the Save button instead. ═══ 5.3. Help ═══ Help Pressing the Help button brings up this help window and shows the main help for the Job Properties dialog. Once in the main help dialog, you can access help topics for any specific job property shown anywhere in the Job Properties notebook. ═══ 6. Common Page ═══ Common Page This page is used to set and view the most "common" job property options users apply to printouts. This page contains the following job properties: Click on the name of a job property to see what it does. ■ Form Connection ■ Print Quality ■ Print Mode ■ Orientation ■ Duplex Options ■ Default Font ■ Color Dither ■ Effects ■ Form Feed Control ═══ 6.1. Form Connection ═══ Form Connection This pulldown list allows you to select the correct Form Connection to print to. A Form Connection represents the combination of a paper tray, size and media type as a single selectable item. This representation closely reflects a real printer's setup (i.e. you place a paper size of a certain media type in a certain paper tray). Linking these properties as a single Form Connection allows the application to know if a desired paper size is installed in a paper tray or not. If it isn't, the user can be told to change the paper size to the correct one for that printout. Form connections can also let applications make sure the correct media type is installed in a paper tray before printing. Note: New Form Connections can be added to this list from the driver's Printer Properties dialog. Simply follow the instructions on the "Connection" page in the Printer Properties notebook. ═══ 6.2. Print Quality ═══ Print Quality This pulldown list allows you to select the quality of printouts based upon the capabilities of your printer. Some printers choose to list print quality by resolution or dots-per-inch (DPI). In this case, a higher DPI typically means a higher print quality (also called higher resolution). Other printers use regular terms to describe the quality of the image. This still usually implies the resolution of the printouts are changing to achieve a selected print quality. Examples of common Print Qualities: ■ Draft, Presentation ■ 300 dpi, 600 dpi ■ Low, Average, High Note: The higher the print quality the longer time it will take for printouts to finish printing. Photo-Quality Printing For best output results printing "photo-quality" graphics please select the highest available print quality listed. ═══ 6.3. Print Mode ═══ Print Mode This pulldown list allows you to select whether your printouts are monochrome or color (if supported by your printer). If the printer allows multiple levels of grayscale or more than one color format those selections will appear in this list as well. This number is sometimes represented as "bits-per-pel" (bpp): ■ 24-bit = 16.7 million colors/grayscales ■ 8-bit = 256 colors/grayscales ■ 4-bit = 16 colors/grayscales Photo-Quality Printing For best output results printing "photo-quality" graphics please select the print mode that uses the most colors/grayscales or highest "bits-per-pel". Note: This driver's monochrome printouts, by default, use 256 grayscales and color printouts use 256 colors (if none are listed). Selecting color print modes will cause printouts to take longer to finish than selecting monochrome print modes for the same document. The more colors/grayscales used on a printout (more "bits-per-pel") the longer the printout will take to finish. ═══ 6.4. Orientation ═══ Orientation This group contains buttons to select how a form is oriented when printing to it. The selection determines which dimension of a paper is to be considered the width and which the height. One of the following buttons can be selected: Portrait orientation typically means that printed output occurs so that the form width is the smaller of the two possible form dimensions. Landscape orientation typically means that printed output occurs so that the form width is the larger of the two possible form dimensions. ═══ 6.5. Duplex Options ═══ Duplex Options This group contains buttons that select how duplexing is performed on those printers that support this option. One of the following buttons can be selected: 1-Sided means printing only occurs on one side of each piece of paper. This is the only option available for printers that do not support duplexing. This is the only option available for printers that do not support duplexing. 2-Sided Book means printing occurs on both sides of each piece of paper. In addition, duplexing occurs so that you continue reading from the front side of a paper to the back side by flipping it over left-to-right like a "book's" page. 2-Sided Flip means printing occurs on both sides of each piece of paper. In addition, duplexing occurs so that you continue reading from the front side of a paper to the back side by flipping it over top-to-bottom (or "flipping" the page over). ═══ 6.6. Default Font ═══ Default Font This pulldown list allows you to select what device font is to be used as the default font for simple text printouts. This setting (when available) usually only effects text printouts from applications that do not explicitely choose a font. Note: Many printer models do not have device font support enabled and so this list will be disabled. ═══ 6.7. Effects ═══ Effects This group contains check boxes of options to apply to printouts. Any of the following can be checked: Mirror Image When selected all printouts come out as if viewed in the face of a mirror. One practical use for this option is to create iron-on tranfers. Note: This option is only available in Portrait orientation. ═══ 6.8. Form Feed Control ═══ Form Feed Control This group contains buttons that select how Form Feeds should be handled at the end of non-OS/2 print jobs. One of the following buttons can be selected: Conditional Ensures a Form Feed is present at the end of every print job None Preserves any Form Feed commands found at the end of each print job Compulsory Always adds a Form Feed command at the end of eac print job Note: When "Conditional" is selected, it is possible that some imbedded Form Feeds characters will not be detected and additional Form Feeds can still occur. ═══ 7. Monochrome Page ═══ Monochrome Page This page contains job properties that affect the appearance of monochrome printouts. This page contains the following job properties: Click on the name of a job property to see what it does. ■ Monochrome Adjustments ■ Darkness ■ Monochrome Colors ■ Foreground ■ Background Note: This driver supports 256 levels of grayscale when printing monochrome. ═══ 7.1. Monochrome Colors ═══ Monochrome Colors This group contains two lists that allow you to select what color is considered the "foreground" and "background" colors for a monochrome printout. Click on the name of a list for more information: ■ Foreground ■ Background These lists contains the following colors: ■Black (default foreground) ■White (default background) ■Blue ■Green ■Cyan ■Red ■Pink ■Yellow Note: This option is only available on some color-capable printers when in a monochrome Print Mode. For non-color printers, the foreground color is always "black" and the backround color is "white". ═══ 7.2. Foreground ═══ Foreground This list allows you to change the foreground ink color used for monochrome printouts to one of the colors in the list. By default, black ink is used for the foreground color on monochrome printouts. Note: This option is only available on some color-capable printers when in a monochrome print mode. ═══ 7.3. Background ═══ Background This list allows you to change the background ink color used for monochrome printouts to one of the colors in the list. By default, the color white is used for the background color on monochrome printouts. Since most printers do not have white ink, the paper's color is assumed to be white and no ink is used. Once the background color is changed from white (default) to any other color, the background color will be generated from mixing the printer's available inks. Note: This option is only available on some color-capable printers when in a monochrome print mode. Only change the background color if really needed since it increases print times and wastes ink. ═══ 7.4. Darkness (Monochrome) ═══ Darkness (Monochrome) This slider adjusts the darkness of monochrome printouts. The control adjusts from a value of 0 (default darkness); where positive values make printouts increasingly darker and negative increasingly lighter. ═══ 7.5. Monochrome Adjustments ═══ Monochrome Adjustments This group contains the job properties that can be used to adjust the appearance of monochrome output. The following adjustments are available: ■ Darkness ═══ 8. Color Page ═══ Color Page This page contains job properties that adjust the appearance of color printouts. This page contains the following job properties: Click on the name of a job property to see what it does. ■ Color Adjustments ■ Tone ═══ 8.1. Color Dithering ═══ Color Dithering This group contains the dithering algorithms and settings that effect certain dithering algorithms. Color dithering is the process of mixing a small set of colors to produce (simulate) many other colors (e.g. Mixing cyan, magenta, and yellow in a printer to produce up to 16.7 million colors). The following adjustments are available: ■ Color Dither Photo-Quality Printing For best output results printing "photo-quality" graphics please select either Steinberg Diffusion or Stucki Diffusion dither algorithms from the list. See Color Dither for more information about specific algorithms and their effects. ═══ 8.2. Color Dither ═══ Color Dither Allows selection of a color dithering algorithm supported by this printer driver to apply to color printouts. Information about a specific color dither algorithm's relative strengths, weaknesses, and performance considerations is provided by clicking below on its name. Click on any color dither algorithm name for more information: ■ Magic Square ■ 4x4 Color Dither ■ 8x8 Color Dither ■ Steinberg Diffusion ■ Stucki Diffusion ■ Ordered Squares ■ Fast Diffusion Photo-Quality Printing For best output results printing "photo-quality" graphics please select either Steinberg Diffusion or Stucki Diffusion dither algorithms from the list. ═══ 8.3. Magic Square ═══ Magic Square This is the default color dithering algorithm for this printer driver. The algorithm is based on a tessalation dither that creates a 16x16 square of randomized values that are used to generate dithered colors. This algorithm accepts adjustments from the HSV Page. Output Quality: For most color printouts which contain 256 colors or less this algorithm provides very nice output containing barely perceivable patterns. Performance: For the output quality this is by far the fastest algorithm you can choose. Choosing a simpler dithering algorithm will not really produce noticeable performance increases. Recommendations: For better performance: try the 4x4 Color Dither or the 8x8 Color Dither. For better quality: try the Fast Diffusion algorithm. For photo-quality: try Steinberg or Stucki Diffusion. Note: The Ordered Square algorithm provides similar performance with slightly different results. ═══ 8.4. 4x4 ═══ 4x4 Color Dither This dither uses an set of four-by-four grids for mixing colors to make other colors. Output Quality: Quality is poor for color printouts with more than 16 colors and the 4-by-4 pattern can be seen easily. Performance: Performance is very good. Recommendations: This algorithm is good for printouts with 16 colors or less and when smooth graphics are not required. For better quality try 8x8 Color Dither or Magic Square algorithms. ═══ 8.5. 8x8 Color Dither ═══ 8x8 Color Dither This dither uses an set of eight-by-eight grids for mixing colors to make other colors. Output Quality: Quality is better than the 4x4 Color Dither on color printouts. The 8-by-8 pattern can be seen on printouts, but not as easily as the 4x4 Color Dither's. Performance: Performance is very good. Recommendations: This algorithm is good for printouts with 16 colors or less and when smooth graphics are not required. For better quality try Magic Square or Ordered Square algorithms. ═══ 8.6. Steinberg Diffusion ═══ Steinberg Diffusion This algorithm is one of the fastest diffusion algorithms around that produces nice output with printouts containing 16.7 million colors or less. Output Quality: Photo-quality output. However, "snakelike" patterns can be found through extremely close inspection. For most printouts, this is not a very important problem. Performance: Performance is much slower then Magic Squares and slightly slower than Fast Diffusion. Recommendations: For better quality try the Stucki Diffusion algorithm. For faster output, try the Fast Diffusion Algorithm. ═══ 8.7. Stucki Diffusion ═══ Stucki Diffusion This algorithm is one of the fastest diffusion algorithms around that produces nice output with printouts containing 16.7 million colors or less. Output Quality: Photo-quality output with no discernable patterns. Performance: Performance is slower then Fast Diffusion or Steinberg Diffusion. Recommendations: For better performance try Fast Diffusion or Steinberg Diffusion. ═══ 8.8. Ordered Square ═══ Ordered Square A tessalation dither similar to Magic Square, but the 16x16 square is filled with random numbers based on a different method. This algorithm accepts adjustments from the HSV Page. Output Quality: For most color printouts which contain 256 colors or less this algorithm provides very nice output containing barely perceivable patterns. These patterns are slightly different then those seen with Magic Square and may or may not be more visually appealing. Performance: For the output quality this is by far the fastest algorithm you can choose. Choosing a simpler dithering algorithm will not really produce noticeable performance increases. Recommendations: For printing "photo-quality" images (or images with more than 256 colors) you should use a diffusion dither algorithm for best results. Please see Steinberg Diffusion or Stucki Diffusion dither algorithms. ═══ 8.9. Fast Diffusion ═══ Fast Diffusion This is the fastest diffusion-based dithering algorithm for printouts containing 16.7 million colors or less. Output Quality: Very good, noticeably better than Magic Square. Performance: Noticeably slower than Magic Square. Recommendations: For better performance try Magic Square or Ordered Square algorithms. For photo-quality try Steinberg or Stucki Diffusion algorithms. ═══ 8.10. Color Adjustments ═══ Color Adjustments Color adjustments modify the amount of ink the printer driver tells the printer to apply to the paper. Increasing the Red, Green, Blue, or Black sliders from zero (the default adjustment) will increase the amount of that color ink used on color printouts. Decreasing the Red, Green, Blue or Black sliders from zero (the default adjustment) will decrease the amount of that color ink used on color printouts. Note: The default Red, Green, Blue, and Black Slider value is zero (0). This value was found, on average, to result in the best color printouts using the currently selected resolution and media type. The following Color Adjustments are available: ■ Red Color Adjustment ■ Green Color Adjustment ■ Blue Color Adjustment ■ Black Color Adjustment Background: Most color printers have been tested at different resolutions on different media types. Based on these results, the printer driver will automatically adjust ink values so that ink does not "bleed" (too much ink) and is dark enough for crisp color output. In case your output still does not come out to your satisfaction these slider controls are available. ═══ 8.11. Red Color Adjustments ═══ Red Color Adjustment This slider increases or decreases the amount of inks that make up the color "red" used on color printouts. ═══ 8.12. Green Color Adjustments ═══ Green Color Adjustment This slider increases or decreases the amount of inks that make up the color "green" used on color printouts. ═══ 8.13. Blue Color Adjustments ═══ Blue Color Adjustment This slider increases or decreases the amount of inks that make up the color "blue" used on color printouts. ═══ 8.14. Black Color Adjustments ═══ Black Color Adjustment This slider increases or decreases the amount of inks that make up the color "black" used on color printouts. ═══ 8.15. Tone ═══ Tone Increasing the Red, Green or Blue Tone values from zero causes the respective color's maximum intensity to decrease. Decreasing the Red, Green or Blue Tone increases the intensity of that color ink on printouts. Note: The default Red, Green and Blue Tone value is 0. This value was found, on average, to result in the best color printouts. ═══ 9. HSV Page ═══ HSV Page This page is used to adjust Hue, Saturation and Darkness (Vividness) of color printouts. This page only affects certain Color Dither algorithms that use an HSV color model. This following color dither algorithms use HSV Adjustments: ■ Magic Square ■ Ordered Square Other color dithers currently ignore these settings. This page contains the following job properties: ■ HSV Adjustments ■ Hue ■ Saturation ■ Darkness ═══ 10. HSV Adjustments ═══ HSV Adjustments Contains sliders that affect a color printout's Hue, Saturation and Darkness (Vividness). This group contains the following adjustments: ■ Hue ■ Saturation ■ Darkness ═══ 11. Hue ═══ Hue This slider adjusts the hue of color printouts. The default value of 0 degrees preserves the meaning of RGB colors for printouts. The hue value can be increased or decreased from 0 degrees causing an RGB color shift for all colors in a printout. Example A color which started out red would be shifted so that it may come out green. ═══ 12. Saturation ═══ Saturation This slider controls the amount of color ink used on color printouts. This control adjusts from 0% (default saturation) where positive adjustments increase the amount of color and negative adjustments decrease the amount of color. ═══ 13. Darkness (HSV) ═══ Darkness (HSV) This slider controls the amount of black ink (or ink mixes that simulate the color black) used on color printouts.
