I had the same problem with a 3 year old Compaq Plus Portable, using MINIX 1.2. using either an Epson LX80 or an Anadex 9275B printer. The problem is that when get_chrome() is called in main.c it uses interrupt 11 to check for mono or color display; and "color card with an 80X25 monochrome monitor" results in "color". So, print_init selects the "PR_COLOR_BASE" or 0x378 for the printer "port_base". But a DEBUG test shows that it is 0x3BC (the PR_MONO_BASE) which can operate the printer. My solution was to change the value in the kernel/printer.c #define statement for PR_COLOR_BASE to 0x3BC. At the same time, I used the version of printer.c from Barry Mc Mullin which came across the net last month. It works well. I am not currently on the net but can recieve mail thanks to Jim Stockwell whose BITnet address is JIM@CALSTATE (CSUMailer (1.3)). Jeff Sacks (Anaheim, CA) (714-956-1784)
