Hi,
Your log isn't showing a problem that I can see. You might want to check
the actual resources that windows is using though and compare that to
the log. Taking a look at your BIOS setup wouldn't hurt either. It does
sound an awful lot like a bad dma or irq value.
Also take a look at /proc/interrupts. IRQ 7 after loading the module
should show a couple of interrupts there caused by the module init code.
The module did have to read data from the printer to pick up that
Lexmark name so I'd say there's hope.
I'd also print to a file in windows for the printer. Then in linux you
can "cp test.prn /dev/lp0". This should insure that the printer is
getting a data stream it likes.
You might try the following on your options line, in sequence, until it
feels better (you lose performance as you go): The first lets the module
figure things out. The second turns off dma use but leaves the ecp
fifo enabled, the 3rd turns off the ECP support, and the 4th leaves you
with only polled i/o.
options parport_pc irq=auto dma=auto
options parport_pc io=0x378 irq=7 dma=none
options parport_pc io=0x378 irq=7 dma=nofifo
options parport_pc io=0x378 irq=none dma=none
Good luck.
Regards,
Tom
