Print Queue displays

[Allen Reese]

IPP is awesome.  Yes it supports the number of pages, and all sorts of
other cool things.  Like automatic printer failover, LPR support. etc.

Netware should be support ign IPP soon, windows sounds like it will also.
Hopefully some decent OS IPP clients/servers will be developed.  ;)
