- WHAT DOES IT DO?
-
- eXtended PrintScreen makes the PrintScreen function more
-
- *** Intelligent. XPS formats text into pages.
-
- *** Efficient. XPS prints screen images in compressed mode at 75
- lines per page.
-
- *** Flexible. XPS allows portions of display text to be printed.
- You select the PrintScreen window.
-
- USING XPS
-
- System Requirements:
-
- -- IBM PC,XT,AT, or close compatible.
- -- A dot-matrix printer attached to LPT1:.
-
-
- Starting XPS:
-
- XPS is a memory-resident (TSR) program. Simply type
-
- XPS
-
- at the DOS prompt.
-
- To run XPS's installation program, type
-
- XPS -i
-
- (See INSTALLATION below)
-
-
- Controlling XPS:
-
- After XPS is loaded, the following key combinations are used to
- activate XPS's features.
-
- LEFT-SHIFT + PrtScr
-
- Do full-display printscreen. This feature is closest to a "stock"
- PrintScreen. The entire display is copied, line by line, to the
- printer. With XPS, however, the text is sent to the printer in
- compressed mode at 75 lines/page. After printing 75 lines, XPS will
- send a form feed to the printer. XPS keeps a running total of lines
- sent to the printer, so each time you activate XPS it "remembers" how
- many lines have been printed. If you wish to clear XPS's line
- counter, use the reset feature described below.
-
- RIGHT-SHIFT + PrtScr
-
- Selected area printscreen. Allows any area of the display to be
- printed. The print window is indicated by a > and < arrow. All text
- under and between the arrows will be printed. Thus the line
-
- The quick brown fox jumped over the lazy dog
-
- would all be printed if the arrows were positioned as follows:
-
- >he quick brown fox jumped over the lazy do<
-
- The XPS window can be adjusted by using the numeric keypad.
-
- Up Arrow - Decrease rows
- Down Arrow - Increase rows
- Left Arrow - Decrease columns
- Right Arrow - Increase columns
- PgUp - Move window up
- PgDn - Move window down
- Home - Move window left
- End - Move window right
- Enter - Print window
- Esc - Exit XPS
-
-
- LEFT-SHIFT + RIGHT-SHIFT + PrtScr
-
- Reset XPS. This key combination resets XPS's line counter and beeps
- the speaker.
-
- INSTALLATION (or, Everything You Never Wanted To Know About Printers)
-
- Computers send bytes to printers. Printers print bytes. So far, so
- good. Unfortunately, different bytes mean different things to different
- printers. When XPS sends control codes to your printer, your printer
- better understand XPS, or printed garbage will result.
-
- Fortunately for those who don't have my kind of printer (IBM Graphics),
- XPS now offers a flexible installation for just about any printer.
- With installation, you to determine the control codes that XPS sends to
- your printer, and, to some extent, when these codes are sent.
- Unfortunately, determining which codes to use is not always obvious.
- Take a few moments and study your printer's manual, then plunge on in.
-
- XPS uses three different control strings:
-
- 1) An initialization string,
- 2) A line-control string, and
- 3) A reset string.
-
- These strings are all optional, but obviously in order for XPS to do
- anything useful it must use one or more control strings.
-
- XPS installation is simple. Just type
-
- XPS -i
-
- at the DOS prompt. The installation menu will appear, and you will be
- prompted for each control string. Type in each control string using the
- following format:
-
- \n\n\n\n
-
- where n = a decimal control code with values ranging from 1 to 255.
-
- Each control character is preceded by a '\', and
-
- -- this is important--
-
- EACH CONTROL CODE MUST BE ENTERED IN DECIMAL
-
- XPS does no error-checking on the data entered, so it is up to you to
- ensure that your codes are correctly entered in the proper format.
-
- The best way to illustrate installation is to use an example from my IBM
- Graphics printer.
-
- My Initialization string looks like this (in XPS's format):
-
- \015\027\051\030
-
- This string sets the printer to condensed mode and changes the linefeed
- to 30/216th of an inch (roughly 75 lines/page).
-
- My Line Control string looks like this:
-
- \013\010
-
- Why a carriage return (013) and linefeed (010) for the line control
- string? Because XPS DOES NOT explicitly send these codes for a new
- line. If you need them, you must install them.
-
- My reset string looks like this:
-
- \018\027\050
-
- This cancels compressed mode and restores default line spacing.
-
- (By the way, the three-digit format is not necessary. Thus, \15 and \015
- are equivalent).
-
- When are these strings sent to the printer?
-
- Initialization -- Just before XPS begins printing text.
- Line Control -- After each line is sent to the printer.
- Reset -- When XPS is finished printing a screen or window.
-
- These three printer control strings permit the same task to be
- accomplished in several ways. On my printer, for example, the
- following control strings do the same job as the ones listed above.
-
- Initialization: \015 (compressed)
- Line Control : \27\74\30 (one-time 30/216th linefeed)
- Reset : \018 (cancel compressed)
-
- Note that this line control string does not properly handle IBM line
- drawing characters. Why? I don't know.
-
- All of this fussing with control codes is a pain. What is obviously
- needed is a industry-standard set of codes that ALL printers respond
- to. Unfortunately, EPSON, the quasi-official standard has not stuck to
- the straight an narrow and keeps changing their codes. For example, on
- my IBM Graphics priner (read EPSON MX-80), the codes for a one-time
- line feed of 30/216ths of an inch are
-
- \027\074\030
-
- Use the above code on an LQ-series printer and you get a 30/180th of an
- inch one-time line feed. And so it goes with other printer
- manufacturers as well. If you don't like having to mess with printer
- drivers and installation, write your printer's manufacturer a letter of
- complaint.
-
- You are also prompted for your printer's name which will be displayed
- when XPS is loaded into memory, but the printer name serves no
- additional function. Type in your name if you prefer.
-
- XPS installation modifies the copy of XPS.COM in the default directory.
- Therefore, always run installation on a backup copy of XPS.COM!
-
- NOTES:
-
- XPS will not operate in graphics modes. Pressing any Shift-PrintScreen
- combination will cause the normal PrintScreen to be invoked. Invoking
- PrintScreen in graphics modes also resets XPS's line counter.
-
- XPS will recognize 40-column text modes (does anyone still use these?)
- and set its defaults accordingly.
-
- XPS currently does not recognize or adjust for >25 row displays.
