I have tried the FILE: approach - with LX-300+, a 9 pin
Epson. The Win95 FILE: seems to be unknown in the DOS
window; so I did the printing in Notepad. The .prn
turned out 401 bytes long. The original .txt was 10 bytes:
8 letters plus 0x0d 0x0a. I then changed the printer setting
back to LPT1 and printed the .prn from DOS (window) EDIT.
The original eight letters, in something like subscript font,
were printed; but so were many spaces and some other characters.
It looks like under Win95 .prn is not exactly what goes to
the port. Also, the eight letters ('abcdefgh') must have
been encoded in some (to me) unusual way: I do not readily see
any 8 consecutive bytes or half-words in the .prn. Nor do
carriage returns and line feeds come in pairs.
By default, Windows prints a lot of stuff as bitmaps. If you can send me
the prn file, I can have a look at it and explain its content to you.
BTW, the proper way of printing prn files is this:
copy /b filename.prn lpt1
Opening the prn file in EDIT will have all kinds of funny effects as the
printer control commands will become misinterpreted.
In Windows 95, you can capture whatever a DOS application sends to the
printer port. While configuring the printer, you just have to tell
Windows that DOS applications will be using this printer, too. (If I am
not mistaken, Win95 is so long ago for me...) Windows will then
intercept all DOS print commands and translate the output, then send it
through its Windows printer driver.
The best thing to start is probably your printer manual. It should
contain all the sequences your printer can understand. After that, you
just have to make up a small programm that can send such command
sequences to the printer port. I will check if I have some introductory
material somewhere...
I could probably whip up a program for sending stuff to your printer in
QBasic (must be lying around here somewhere *g*) :)

Andre

Re: [Freedos-user] Printer driver
Hi Edmund, there is no such thing as a generic DOS printer driver for a particular printer. You have to compile the printer commands all by yourself and just send them to the printer port. Depending on the printer, available printer commands will be listed in its manual. Generally speaking, ink printers and cheap lasers (GDI printers) are unsupported due to lack of documentation. On ink printers, text mode output may or may not be available. Common lasers use PCL which is rather good documented. If you need a particular problem solution, let us know. :) Best regards, Andre Edmund Swylan wrote: How does one go about finding a DOS driver for a given parallel port printer (eg Epson Stylus C84, Epson LX-300+)? The Epson sites and the more often referenced driver sites do not seem to offer DOS drivers for the printers I am interested in. But maybe some of the offered drivers will do or perhaps there is a DOS specific survey site or two. es --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems?
