Description of problem:
It's impossible to cancel a print job waiting in a remote LPD queue, because
print jobs submitted locally disappear from local queue almost instantly and
CUPS doesn't show remote queue contents like for example LPRng does.

Version-Release number of selected component (if applicable):
1.2.10-3.fc6

How reproducible:
Always.

Steps to Reproduce:
1. Configure local CUPS queue for a remote LPD (LPRng) printer
2. Submit a print job when remote printer is still printing something else
  
Actual results:
The print job disappears from local print queue almost immediately and it's
impossible to cancel it, because CUPS-provided lpq doesn't support remote
LPD-compatible servers.

Expected results:
lpq should either show the submitted job in the local queue until it is
completed or lpq should show remote queue contents and allow their control, per
RFC-1179. If it claims to be a lpq replacement, then it should be compatible.

Additional info:
I would replace CUPS with LPRng, but gtkprint is broken and doesn't show LPR
printers from printcap, like libgnomeprint did.
