You could probably just switch off printing in dosemu if you dont need to print anything? Just print into a file and then print that later, manually then. My configuration (.dosemurc / dosemu.conf) now says: $_printer = "file file" Which means LPT1 and LPT2 print to "file" defined in /etc/printcap. Hmm. Now that I look at it, my printcap no longer has "file" :-p Which proves that I hardly ever print in DOSEMU... Before, I had: $_printer = "deskjetbw" Which is the cups name of printing to my Deskjet in greyscales. The default is $_printer = "lp" as far as I remember... $_printer_timeout = (20) # idle time in seconds before spooling out Might also be interesting. Note that DOSEMU probably assumes that you print plain text without any graphics or printer control codes. The layout is then done by some default text handler of CUPS, e.g. a2ps with 2-up layout. If you want to print with graphics, try to tell your DOS apps that you have a laser printer. CUPS will then, hopefully, automatically recognize that you sent postscript to it. Once when I was working on GRAPHICS (GRAPH-PS, GRAPHPIN, GRAPH-HP) I think I had hand-edited the /etc/printcap or similar so the raw data ended up in a file which I then "harvested" to have a look at the raw contents to check the escape sequences etc. From that time I also have a simplistic parser for ESC/P2 graphics data to convert that data into a PCX picture or similar. You can also use PPM tools or other general purpose image converters to "digest" printer data.
