parport question

parport question

[Ognen Duzlevski]

Hi,

I have sent this question to the people listed in the parport
kernel directory (the maintainers) but have yet not received a reply and
I am not sure if this is exactly a linux-kernel question.

I have a printer that worked fine under linux (redhat/lexmark 3200) for a
long time, then I switched over to 2.4.18 and debian and it stopped
working. I compiled the parport support into the kernel, I did that with
2.4.19, I did it also as modules, I tried 2.5.45, still won't work, not
even a cat test.txt > /dev/lp0

The dmesg shows that the printer is recognized correctly:

Nov  9 13:06:32 gemelli kernel: parport0: PC-style at 0x378 (0x778)
[PCSPP,TRISTATE]
Nov  9 13:06:32 gemelli kernel: parport0: irq 5 detected
Nov  9 13:06:34 gemelli kernel: parport0: Printer, Lexmark Lexmark 3200
lp0: using parport0 (polling).
lp0: console ready

The BIOS has a ton of settings such as "auto" or "normal" - I have tried
them all, tried forcing the DMA / IRQ from the BIOS and then feeding these
values to parport_pc, still won't work. I have tried all combinations of
Normal, ECP, ECP+EPP or EPP solely, won't work.

I then installed vmware and windows nt as a guest OS, under the same
kernels. I set up parport0 to be used by vmware and, it prints from
Windows nt (so I know the printer is fully functional).

Any ideas, help would be appreciated. Sorry if this is not the place to
post the question but I have tried google, linux-printing.org, usenet to
no avail.

CHeers,
Ognen

It sounds like a userspace problem.  The information about this printer 
I've found on the web shows it to be a GDI printer (ie. all the smarts 
are in the software driver, not in the printer), which means sending 
text to it will never print anything.  You will need to check the 
configuration of ghostscript or whatever userspace printer driver debian 
is using.

I have a similar situation, I couldn't program the SPP parallel interface on 
a Debian/Woody + kernel 2.x + M810 Motherboard. It simply doesn't give me any 
(electrically) anwser. 

A question please, what is your motherboard and processor ? 

If I have any news I'll give a anwser.

bye.
