EZSET DESCRIPTION ----------------- EZSET is a utility program designed to make it easy to access ALL of your parallel printer's features, whether directly available from the printer's control panel or not. Unlike other methods, which either involve programs that come with a predefined library of printer codes (none of which usually match your printer), or which involve writing BASIC programs or batch files, all you need to use EZSET effectively is your printer's manual. EZSET is designed to make it EASY to send your printer's control codes from the command line or from inside batch files. In addition, EZSET printer strings can be customized to go automatically to any printer port, using any printer online return value. HARDWARE REQUIREMENTS --------------------- EZSET should work on any IBM-compatible computer, running DOS 2.1 or better. EZSET'S LIMITATIONS ------------------- EZSET will manage a printer string library containing an arbitrary maximum of 255 printer strings, with each printer string a maximum of 255 characters in length. EZSET will output strings only through parallel ports 1 through 3. EZSET will not output through serial ports. HOW EZSET WORKS --------------- EZSET has two modes, an editor mode and a command line mode. The editor mode is used to input and edit printer strings. The command line mode is used to send strings to a printer. Typing EZSET [ENTER] calls EZSET up in editor mode. Here is what you'll see: Exit Program Edit A Printer String Enter A New Printer String Above the menu choices there is a line telling you to use the arrow keys to move the light bar and to press [ENTER] when your choice is highlighted. To leave EZSET you would simply highlight "Exit Program" and press the [ENTER] key. This style of menu is EZSET's main method of getting input, making it difficult to go wrong. Here is what the different main menu choices do: 2 Exit Program ------------ Leaves EZSET. Edit A Printer String --------------------- If there are already some strings defined (in a file called EZSET.LIB), choosing this option gives you a chance to modify them. Enter A New Printer String -------------------------- Choosing this option gives you an opportunity to enter a new string, including determining which printer port the string will go to, and defining what the online return code should be. Both editing and entering a new string will be covered in detail a little later on. USING EZSET IN COMMAND LINE MODE -------------------------------- After there has been at least one string entered, using EZSET's editing mode, you can send it to your printer by typing EZSET stringname [ENTER] If the printer is online (as determined by the return code saved with the string) the string is sent to it. If the printer is off-line you are told so and EZSET exits with a return code of 255. EZSET's ability to return an exit code makes it possible to do conditional branching in a batch file. An example batch file could be something like this: ECHO OFF EZSET stringname IF ERRORLEVEL 1 GOTO END programname :END Notice that EZSET uses the highest possible ERRORLEVEL return code. This means that "IF ERRORLEVEL 255 GOTO END" would work equally well. In addition to the return code, when a printer is offline a message to that effect is printed to the screen. And, if you type a nonexistent string name (one that isn't in the library file), EZSET will say so, likewise with a return code. EZSET is supplied with a sample library of printer strings for an NEC Pinwriter printer. If you don't have a Pinwriter, feel free to play with and experiment with them. When you've gotten 3 familiar with EZSET they can be erased by deleting the file EZSET.LIB. Then you'll have a "fresh slate" for inputting your own printer's strings. EDITING STRINGS --------------- From the main menu press the [DOWN ARROW] key once, to highlight "Edit A Printer String", and press [ENTER]. In the center of the screen you'll see a sorted list of all available printer strings. Across the bottom of the screen are all of the pertinent control keys. Notice that you can scroll the string list by using any of the "vertical" cursor-movement keys ([UP ARROW], [DOWN ARROW], [PgUp], [PgDn], [HOME] and [END]). To the left of the list box is a status indicator showing what the highlighted string's port setting is. Pressing [F9] will take you to a light bar menu that lets you choose which printer port a particular string should always go to. The port selected from the "Edit A Printer String" menu applies ONLY to that particular string. The same menu, reached from the "Enter A New Printer String" main menu selection, will enable you to change the present session's default port setting. All strings entered after changing the default port will have that as their setting. To the right of the list box is a status indicator showing what the highlighted string's online code is. Before a string is sent to a printer from the command line, EZSET "interrogates" the printer to see if it's on and on line, to prevent your computer from going into the dreaded "timeout". Truly, for most printers the default value for this will be all that is necessary, so you probably won't need to use this feature. But if you ever encounter a "rogue printer" (as I have) that insists on responding differently than others, it can be handy. Pressing [F10] will take you to yet another light bar menu enabling you to (1) interrogate the printer (with an informative bitwise readout of the return code), (2) to return WITHOUT changing the set value, (3) to return WITH a new value, and, finally, (4) to restore the default value if you find you've chosen unwisely. An online code selected here (from the edit menu) applies ONLY to the highlighted string. Changing the default is possible from the "Enter A New Printer String" menu. Pressing [DELETE] inside the edit menu will erase the highlighted string. Use [DELETE] cautiously; if you erase something you wish hadn't you will have to exit to the main menu (by pressing [ESC]) and then leave the program (by pressing [ENTER]). When asked if you want to save changes to disk, answer "no". Everything done in the current session will then be gone. To try out what effect a particular string has on your printer, pressing [F5] will send it to the printer. It's often useful to be able to enter a string, try it out, and then go back to the editing screen to modify it on the spot, if necessary. 4 Pressing [ENTER] takes you to the byte editing screen, with the currently highlighted string displayed for editing. The byte editing screen will be described later, since it's where you go from the "Enter A New Printer String" menu, as well as from this one. ENTERING A NEW STRING --------------------- From the main menu press down [DOWN ARROW] key twice (or [UP ARROW] once), to highlight "Enter A New Printer String", and press [ENTER]. In the middle of the screen you will see a box for entering a string name. Unlike DOS path- and file-names, anything goes with a string name: letters, numbers and spaces are all okay. Everything is automatically converted to uppercase as it is entered. To the left of the entry box, similar to the editing menu, is a status indicator for the output port. Where the indicator said "String Port Value" in the editing menu, however, it now says "Current Port Value", indicating that the OVERALL, or DEFAULT value can be changed from this menu. Pressing [F9] takes you to a scroll menu where you select which printer port all subsequently entered strings should go to. To the right of the entry box is a status indicator for the printer online value. Where, in the edit menu, it said, "String Online Value", it now says "Current Online Value", indicating that a change (by pressing [F10]) will change the default value, affecting all subsequent (new) strings. Pressing [ENTER] after entering a string name will take you to the byte editing screen, where the individual bytes of a new setup string can be entered. THE BYTE INPUT/EDITING SCREEN ----------------------------- Pressing [ENTER] from both the "Edit A Printer String" menu or the "Enter A New Printer String" menu brings you here. Across the middle of the screen is a display of string bytes, given in the first row as decimal numbers, and in the second as hexadecimal numbers. This makes it easier to enter and edit a string, since a majority of printer manuals use both to illustrate escape codes. Above the byte display are the byte numbers. Below the display is an arrow, used as a cursor indicating which byte we're operating on. On the bottom of the screen is a list of applicable keys: [ESC] Returns you to the previous menu. [-><-] The left and right arrow keys move the arrow cursor left and right within the string. [PgUp] "Jumps" the cursor 15 bytes to the left, towards the 5 beginning of the string. Scrolls backward through the string. [PgDn] "Jumps" the cursor 15 bytes to the right, towards the end of the string. Scrolls forward through the string. [HOME] Repositions the cursor to byte 0 of the string. [END] Repositions the cursor to the first byte FOLLOWING the end of the string. Used for appending new bytes to the end of a string. [INS] The insert key moves the bytes above and to the right of the cursor one slot to the right, opening up a space for inserting a new byte. [DEL] Deletes the byte above the cursor. Above the byte display are directions: "Input the byte of the printer string indicated by the [UP ARROW] using <C>haracters, <D>ecimal numbers, or <H>ex numbers, then press [ENTER]. . ." followed by a prompt. EZSET's ease of use comes partly through its ability to accept a byte value as a character, decimal number or hex number, all of which can be equivalent, depending on how they are interpreted. After entering a value and pressing [ENTER], EZSET says "Is this a <C>haracter, <D>ecimal number or <H>ex number?" at which point you must press "C", "D" or "H", to indicate how what you've typed should be interpreted. A few examples: To enter an escape code (ASCII character 27), DON'T press [ESC], which will only return you to the previous menu. Instead, type 27 [ENTER] D You could equally well have typed 1b [ENTER] H since 27 decimal is THE SAME AS 1b hex, and EZSET has no trouble keeping them straight if you tell it what the number base is ("D" for decimal, in the first instance, "H" for hex in the second). Entering literal string characters (as in the letter "A") is just as easy. Just press "C" to indicate that this is a <C>haracter. If you type a string more than 1 character long and tell EZSET 6 it's a character, only the FIRST BYTE of the input will be interpreted as a character. As each new byte is entered the decimal and hex values of that byte will be displayed over the arrow cursor, which will then move to the right, awaiting the next byte. As the number of characters entered grows, the byte display will scroll to keep up. You can move back and forth inside the string for editing, at any time, using the cursor movement keys detailed above. When you're through entering or editing your string, press [ESC]. TROUBLESHOOTING --------------- Most of the time, looking up printer codes and inputting them to EZSET will be a trouble-free operation. But what to do if the results are not what you expect? This section suggests a method for "cracking the tough nuts". When you cannot make your printer behave as you wish, it may be helpful to see how another program does it. This presupposes, of course, that you have a word processor or the like that is able to switch your printer in the desired fashion. The first step in finding out how this other program works its magic is to capture its output to a disk file, to PRINT TO DISK. Most word processors and text editors are able to do this. If yours isn't, it is still possible to capture print output to a disk file by using one of the many shareware utilities available for the purpose. Check with your local shareware disk distributor, or, if you have a modem, log on to your favorite BBS and conduct a keyword search using, for example, "PRINT TO DISK". That should net some possibilities. Once you are set up to print to disk, simplify your formatting as much as you can: no top margin, no left margin, and so on. Then, type "Hello!" and print this file to disk. Call the file HELLO. The next step involves using DEBUG, a utility that comes with DOS, to help you decipher what's going on. Here's what you do: >DEBUG HELLO -D 23CC:0100 1C 40 1B 36 1B 74 01 1B-43 00 0B 1B 6B 00 1B 78 23CC:0110 01 1B 50 1B 52 00 1B 4A-B4 48 65 6C 6C 6F 21 0D 23CC:0120 1B 4A FF 1B 4A FF 1B 4A-FF 1B 4A FF 1B 4A FF 1B 23CC:0130 4A FF 1B 4A FF 1B 4A 0F-1C 40 0D F9 EB 0A 50 B0 23CC:0140 03 B4 FF E8 03 00 58 F8-C3 57 26 8B 7F 04 2E 89 23CC:0150 3E C8 88 26 88 05 26 88-65 01 50 2E A1 D7 88 26 23CC:0160 89 45 02 58 3C 01 75 0A-26 89 55 04 26 89 4D 06 23CC:0170 EB 5A 3C 02 75 06 26 89-55 04 EB 50 3C 07 74 E8 To the right of this (which there isn't room to show here) you would see a straight ASCII representation of the above. At offset 119 hex there is our friendly "Hello!". Your own "hello" file will certainly differ from this one; what you are interested 7 in is everything preceding the text. It's now time to call your printer's manual into play again. Start at the beginning, looking up each code in turn, and write down what it does. By the time you get to the "Hello!" you should have a good idea of exactly what steps are necessary to get what you want out of your printer. Since EZSET accepts hexadecimal input, there is no need to translate, and it should now be possible to get the results you want.
