PRINTING: samba / cups / lp0 problem

Mandrake Linux 10.1, cups 1.1.23, printer connected as "Device URI:
parallel:/dev/lp0"

I am having trouble with my printer. I am trying to share my HP deskjet
connected to my new Linux box (Linux newbie... sorry), and it works...
almost.

If I boot my Linux box, and try to print from my Window XP machine the
print job goes off ok, but nothing prints. When I check the cups print
manager (via web browser) I see the job in the queue, but when I check
the printer section I see the printer is currently shown as...

"Printer not connected; will retry in 30 seconds...".

Now, if I go on to my Linux box, log in, launch mandrake's control
center (mcc as root), select the hardware tab, and double click
printers, a couple of things happen...

1) I see the following text in the terminal window from which I launched
mcc...

ERROR: Module lp does not exist in /proc/modules
ERROR: Module parport_pc does not exist in /proc/modules
ERROR: Module parport does not exist in /proc/modules

2) The printer immediatly starts printing the job I sent from the XP
machine.

3) printerdrake shows the printer

4) refreshing the cups web interface shows the printer as...

"Printer State: idle, accepting jobs."

When I go look in the message log I can find this series of entries
which seems to correspond to the printer coming back to life...

DESKJET 930C
Feb 21 21:33:07 localhost kernel: lp0: using parport0 (polling).

Any insight would be GREATLY appreciated.

Thanks,

.... but bottom line the printer starts working. More detail I just
pulled from syslog...

Somewhere in the middle of that the printer starts printing the jobs in
the cups queue. I'm guessing about the time the kernel sees parport0.

So... how do I get the kernel to see this correctly at boot time?

Just in case someone has the same problem...

I solved this by creating a script in /etc/rc.d/init.d that executed these
lines...

/sbin/rmmod lp
/sbin/rmmod parport_pc
/sbin/rmmod parport
/sbin/modprobe parport_pc
/sbin/modprobe lp

I then used chkconfig to run this script on all boot levels.

Seems to have done the trick... parallel port printer is now available
immediately upon boot up.
