Description David Edwards 2011-07-03 18:59:35 UTC

I am unable to install my HP Laserjet 2100 on a parallel port using CUPS. The system acts as though my parallel port does not exist. It appears that udev does not statically support /dev/lp0. Could someone explain this to me and how I would add the device?

Comment 2 Kay Sievers 2011-07-08 13:43:37 UTC

This should make it work:
  mknod /lib/udev/devices/lp0 c 6 0; chgrp lp /lib/udev/devices/lp0

Newer cups packages will do that:

Comment 3 David Edwards 2011-07-09 03:39:21 UTC

I tried running "mknod /lib/udev/devices/lp0 c 6 0; chgrp lp /lib/udev/devices/lp0" and lp0 is created but I am still unable to detect the device with CUPS.

This is related to a missing kernel module in our current RHEL-6 kernel, moving to kernel component.

Thanks & regards, Phil

Any update to this?

Comment 6 RHEL Program Management 2011-10-07 15:40:05 UTC

Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Comment 7 Prarit Bhargava 2012-07-10 17:28:02 UTC

RHEL6 is unlikely to have parallel driver support as most parallel printer support has been obsoleted by USB printer support.

As a workaround, can you try using a $5 usb to parallel adapter?  It is likely the printer will work under those circumstances.
