I have used EPSON wide carriage and OKI 390 turbo letter width dot matix in
EPSON ESC/P and ESC/P2 modeS with custom code I wrote. As long as the
correct escape code sequences were sent to the printer the output whether
character based or graphics worked. One thing is to be sure you have good
documentation of how the escape sequences work. The web is a ready resource
to locate that information. The old printed 20th Century documentation from
the late 1980's and early 1990's was not of great quality just a listing of
the sequences.
Thing would go-bad when the communications path to the printer was not
working correctly. An example was for a printer port driver was not sending
characters with the 8th bit set. That really ate up some time to figure
out.
Check to be sure the escape codes are actually reaching the printer. How
would you figure that out.
1.) divert the printer output to a file from LPTx:
2.) use a Hex editor or a programmer's text editor with a Hex mode such as
you can get from http://www.vedit.com, a really high quality editor.
3.) examine the actual Hex code series that the file indicates the printer
receives to see if the printer is getting proper escape sequences.
OR
Write short programs that output short escape sequences to test the printer
behavior.
