Printer problem:
machine: ZEOS 386/20
os: Microport SysV/AT rel. 2.4 (I KNOW, I'm saving my money :-))
printer: Panasonic KXP-1092i, Citizen MSP-10
port: /dev/lp1
Problem: the printer prints _excruciatingly_ slowly. When I boot DOS on the
same machine, no problem, the printer speeds along, just as it should. I get
the same results whether I use the command "lp /etc/passwd", or
"cat /etc/passwd > lp1".
I just purchased and set up the new machine, loaded the software from the
original SysV/AT disks, and transferred over my user file system.
The lp spooling system is set up just as it is on a Compaq system here which
works perfectly with the same printers.
Here are my lp devices:
crw------- 2 lp sys 7, 1 Feb 19 19:16 /dev/lp
crw------- 1 lp sys 7, 0 Mar 18 1986 /dev/lp0
crw------- 2 lp sys 7, 1 Feb 19 19:16 /dev/lp1
crw------- 1 lp sys 7, 2 Oct 19 1986 /dev/lp2
One thing that _is_ really strange is that UNIX prints on lp1, NOT lp0, and
DOS prints on lpt1:. Does that make sense?
This problem is driving me NUTS. Anyone have similar experiences?

I had the same problem on Interactive Unix 386/ix. Things would print very slowly under Unix, and fine under DOS. The solution was very simple: DOS does not look at the IRQ lines while printing, while Unix does. Just double check the settings of your IRQ lines for your printer card, and make sure that they match the normal AT standards (I know that IRQ 5 and IRQ 7 are involved, but I don't have in front of me which is which). If you have any other problems, let me know via E-Mail.

The PC hardware often claim to send interrupts correctly when the printer is ready to receive. However, this is in most cases a d*mned lie. You will have to use the polling lp device instead (lp1p). I don't really remember how to set this up out of my head. Check the documentation. -- Robert Claeson E-mail: rclaeson@erbe.se ERBE DATA AB
