My printer was working perfectly. I rebuilt the kernel allowing
autoprobe. Printer no longer responds even to
cat lptest > /dev/lp0 where lptest is a small text file
responds normally but nothing is printed and nothing is in the print que.
cat /proc/ioports shows the correct value (0378-037f) for
cat /proc/parport/0/irq reports none (should be irq 7 but is
Documentation/parport indicates that a lilo command parport=0x378,7
should work but /sbin/lilo rejects this line placed anywhere in
lilo.conf. The documentation also implies that the irq value reported
by cat/proc/parport/0/irq can be changed but I don't understand how.
It seems to me that everything is working normally but the printer is
not receiving the transmission. The printcap file is unaltered and lp
is directed to lp0.
Where is the missing link?
