Suddenly, my Seawolf platform cannot send a signal
to the parallel port (/dev/lp0). My printer used
to work fine locally from my Linux machine.
Now it only prints from a Windows 98 machine.
I tried through the 'printtool', and directly with
lpr and cat. Everything appears to be correctly
done by the OS, but the printer does not print
anything, not even garbage. lpq informs that the
spool is empty, printtool in test mode informs that
the print daemon was restarted and that a file has
been sent to the printer, but nothing is actually
printed. It is very frustrating.
