There is no possibility to think of the 'cat' command because it seems
that Linux can't see neither the lp port nor the printer. I could see
the difference between Linux and Windoze during the boot process:
Windoze is about to 'initialize' the printer on the lpt port even if it
is not still 'installed' under the Control Panel an/or Printers. But it
still reports that it sees both the lpt port and the printer. It just
moves the mechanics for a while and asks for a sheet of paper if tray is
empty etc.
That is an action that I don't get when I boot Linux. It looks to me
that it just tries to do the similar thing like Windoze but it doesn't
finish it in the right state: after the booting of Linux, my printer
remains in a position where only 'power' LED is lite (but not 'online'
and 'paper out') so I am not able to feed it a paper and continue with
printing.
I was suggested to add some lines:
alias parport_lowlevel parport_pc
options parport_pc io=0x378,0x278 irq=7,auto
into /etc/conf.modules and after I did it, it 'recognized' lp0 port and
I can make a print page etc. It continues to work until the next re-boot
of the machine. After doing next re-boot it can't handle the printer
again.
Any idea?
