Parallel printing stopped working
Hello,
I use an old LaserJet HP 4L plugged on the parallel port that was
functioning perfectly.
If I upgrade the kernel above 2.6.11 (I'm using the debian package
linux-image amd64-k8), printing does not work anymore.
A command issued as root like echo -en "\rTest\r\f" >/dev/lp0 makes the
printer led blinkle but the page is not printed, pushing the printer button
to force a page feed gives a page with garble printed.
I have a Asus A8N-SLI motherboard and I have not yet tried to fiddle with
the bios parameters for the parallel port. Something must have changed in
recent versions of the the parport_pc module but I have no clue (and Google
either) what it is.
Downgrading to 2.6.11 solves the problem.
tombouctou:/var/log# uname -a
Linux tombouctou 2.6.12-1-amd64-k8 #1 Wed Sep 28 02:31:26 CEST 2005 x86_64

tombouctou:/var/log# dmesg | grep parport
