- PrintCache \GOODIES README
- ---------------------------
-
- In this sub-directory you'll find a collection of utilities and files that
- are not essential for using PrintCache, but which might come in handy.
-
- Below, you'll find a brief description of each. Those utilities that require
- a more complete description have additional documentation following the
- summary below.
-
-
- GOODIES FOR EVERYBODY
- ---------------------
-
- o PCMENU.COM -- This is a non-pop-up version of the
- PrintCache pop-up menu. It is included for those of you
- who would like to run PrintCache in the "/Small" mode
- (which disables the pop-up menu). Run PCMENU just like any
- other DOS program.
-
- o NULLCABL.DOC -- This file shows the wiring diagram for a
- null modem cable (the kind most often used to connect a
- serial LaserJet or PostScript printer to a PC).
-
-
- GOODIES FOR LASERJET USERS
- --------------------------
-
- o CABLTEST.EXE -- This utility is included to help diagnose
- problems with flaky cables. A more detailed description
- follows this section.
-
- GOODIES FOR POSTSCRIPT USERS
- ----------------------------
-
- o GENERAL TIPS -- hooking up a PostScript printer to your PC
- can be a bit frustrating. You'll find some tips from our
- support staff in this file.
-
- o EHANDLER.PS -- This is Adobe's PostScript error handler.
- It can be very helpful in diagnosing communications problems
- with PostScript printers by ejecting a sheet with a printed
- error message any time an error occurs. (Normally, errors
- just cause the printer to "flush" the print job and no
- page is printed at all -- which can be a bit mysterious.)
- More details follow.
-
- o PRINTPS.PS -- This utility prints out information on the
- PostScript printer's internal settings. It is most helpful
- if you are not sure of your printer's serial port settings.
- More details follow.
-
- o DOWNLOAD.EXE -- A replacement for the Adobe font downloader
- that allows you to download fonts to parallel printers, or
- printers set for high speed baud rates. More details follow.
-
-
-
- LASERJET CABLE TEST UTILITY
- ---------------------------
-
- There is a program on your disk called CABLTEST.EXE, which is designed
- to test the ability of your printer port and cable to transfer data to
- your HP LaserJet printer. It will print a grid on your LaserJet. A flaky
- cable will have a tough time printing the grid correctly. A good cable
- will have no problem.
-
- The usage of this program if you are testing a parallel port is:
-
- CABLTEST port
-
- where the port is: lpt1, lpt2, lpt3, or lpt4.
-
- If you are testing a serial port, the usage is:
-
- CABLTEST port:baud
-
- where the port is: com1, com2, com3, or com4.
-
- The baud rate is the speed at which your computer communicates with
- your printer. For example, if you wanted to test your printer data
- transfer on com1, at 115.2K baud, you would enter:
-
- CABLTEST com1:115200
-
- In order to create a file of this same grid to copy to your printer
- so you do not have to recreate the file each time you test, you
- would enter:
-
- CABLTEST filename
-

- General Purpose PostScript Installation Tips
- --------------------------------------------
-
- Here at LaserTools we often talk to people having trouble setting up their
- PostScript printers with their PCs. Nine times out of ten, these problems
- have to do with getting a PostScript printer set up via a serial connection.
- In those cases it usually is due to a bad cable, or less often, an improper
- communication protocol between the PCs serial port and the printer. Our rule
- of thumb tips follow:
-
- o Connect Via Parallel -- If your PostScript printer can do it, use
- a parallel port to connect it to your PC. Not only is parallel a
- lot easier to hook up (you don't have to fuss with cables, or port
- configuration), but parallel is also a lot faster than serial.
-
- o If You Have to go Serial -- Our best advice is make sure your
- cable is wired correctly before you go too far diagnosing a
- serial problem. A lot of problems are simply due to a mis-wired
- cable. You'll find a null modem cable diagram in this
- sub-directory (in the file "NULLCABL.DOC"). Once you are sure of
- your cable, you need to make sure that your printer and PC are
- both running the same baud rate and handshaking. Most of the
- PostScript printers default to XON/XOFF handshaking (which
- PrintCache supports), but you may find it easier to switch
- the printer to use DTR handshaking (sometimes called "hardware
- handshaking"). Most printers connected to PCs use DTR handshaking
- so its usually easier to go with the flow and set your PostScript
- printer to run that way too. Consult your printer manual for
- information on how to change your printer's handshaking.
-
- One other question that comes up with PostScript printers
- connected via serial is how to set word length and parity. In our
- experience, you always set your PC to use an 8 bit word length and
- set parity to none. You set your printer the same way unless it
- no option for parity none (for example, the NEC LC890 cannot use
- a parity=none setting). If your printer has no parity=none option,
- set it up for 7 bit word length, and set parity to "space" (this
- is equivalent to 8 bit, parity none, so you can continue to run
- your PC at 8 bit, parity none, while your printer is set for 7 bit,
- parity "space," without any difficulty).

-
- PRINTPS.PS
- ----------
-
- The file "PRINTPS.PS" can help you diagnose problems with your PostScript
- printer. PRINTPS.PS is a short PostScript program that prints out the
- PostScript printer's internal settings -- including the printer's serial port
- parameters.
-
- If you are having trouble getting your PostScript printer to communicate
- reliably via serial connection, it may be helpful to copy PRINTPS.PS to
- your printer to find out exactly what your printer's serial settings are.
- Unreliable communication via serial is usually due to a cable problem,
- or a mismatch of the PC's serial port settings, and the printer's serial
- port settings.
-
- To print this file to the printer, you'll need to have the printer connected
- to your PC, with a serial cable that you know works, powered-on and ready to
- print in PostScript batch mode. Then, just copy the file to the printer. For
- example:
-
- COPY PRINTPS.PS COM1:
-
- The above command will copy "PRINTPS.PS" to the first serial port, com1.
- If you are not using either Trading Post or PrintCache to initialize the
- serial port of your PC, then you will need to do so yourself with the
- appropriate DOS MODE command.
-
- The page which PRINTPS.PS produces will give you a lot of you information
- about your PostScript printer's internal settings. Usually, you'll be looking
- at just two of the numbers: sccbatch baud, and sccbatch option. The first
- number is just the baud rate. The second number is the serial port
- protocol. Typically the first number is "9600" for 9600 baud, and the second
- number is "0" for Xon/Xoff communications. In some cases the second number
- is "4" which means the printer is set for DTR communications.
-
-
- EHANDLER.PS
- -----------
-
- The file "EHANDLER.PS" is the Adobe Error Handler program. It is a short
- PostScript program that prints out most of the PostScript printer's error
- messages. The error handler can be very helpful in diagnosing problems
- you run into installing or using a PostScript printer. To use it, just
- copy it (i.e. "download" it) to the printer. It will remain resident in
- the PostScript printer until the next time you turn the printer off.
-
- To print this file to the printer, you'll need to have the printer connected
- to your PC, with a serial cable that you know works, powered-on and ready to
- print in PostScript batch mode. Then, just copy the file to the printer. For
- example:
-
- COPY EHANDLER.PS COM1:
-
- The above command will copy "EHANDLER.PS" to the first serial port, com1.
-
- If you are not using either Trading Post or PrintCache to initialize the serial
- port of your PC, then you will need to do so yourself with the appropriate
- DOS MODE command.
-
- The error handler will print out a page if the PostScript printer encounters
- an error. The page will note the type of error and, if appropriate, the
- offending PostScript command.
-
-
- DOWNLOAD.EXE
- ------------
-
- Welcome to the LaserTools' PostScript font downloader. This program works
- in conjunction with either Trading Post (the LaserTools' PostScript
- Printer Personality Manager), or PrintCache (the LaserTools' print buffering
- utility). If you are using Trading Post, be sure it is version 1.1 to be
- compatible with this version of Download.exe. If you have an earlier version of
- Trading Post, call LaserTools to upgrade.
-
- This program is used to download fonts into your PostScript printer. These
- fonts will be available to all succeeding print jobs until you "clear" your
- printer memory or turn your printer off.
- With Trading Post or PrintCache, you can save a dramatic amount of time
- downloading fonts, because DOWNLOAD is not restricted to operating your
- printer at the slow 9600 baud communications speed. Your printer can
- be connected at 19200, 38400, or 57600 baud. DOWNLOAD will also work
- with parallel port printers and networked printers.
-
- In addition, you can save additional time because of PrintCache's high speed
- print buffering, so your font downloading will seem nearly instantaneous
- compared with other downloaders.
-
- To download fonts, run:
-
- DOWNLOAD fontfilename
-
- You can enter one or more font file names with each command. You will need
- to know the font file name (rather than the actual font name). DOWNLOAD
- assumes the filename ends in .PFB, and looks in the current directory, the
- \PSFONTS directory on the current drive, and the \PSFONTS directory on the
- C: drive.
-
- By popular request, the underscore characters in the Adobe font file
- names are no longer required. Thus, to download the Letter Gothic Bold
- font (file name LGB_____.PFB), you can refer to the file name as
- "LGB", and use the command "DOWNLOAD LGB".
-
- You can use any of several command line switches while downloading:
-
- /C Clears all downloaded fonts and programs from your printer memory,
- a process which takes from 30 to 60 seconds of your printer's time.
-
- /Pnn To specify your printer password (the default is 0, so you only
- need to use this command if you have changed your printer's
- password).
-
- /A To download the Apple LaserWriter patch for version 23 printers.
- The patch is contained in a file called PATCH23.PS provided by Adobe
- on your font disks. DOWNLOAD assumes that PATCH23.PS will be in the
- current directory, in \PSFONTS, or in C:\PSFONTS.
-
- For example:
-
- DOWNLOAD LG.PFB {downloads the font "LG______.PFB"}
-
- DOWNLOAD LG {also downloads "LG______.PFB"}
-
- DOWNLOAD LG LGB {downloads both "LG______.PFB and
- "LGB_____.PFB"}
-
- DOWNLOAD /C {clears all downloaded fonts from
- the printer's memory}
-
- DOWNLOAD LG /P76 {downloads using the password "76"}
-
- Happy printing, and thanks for ordering a copy of PrintCache!
