Printing to cups on Ubuntu from Mac
 

I am having trouble with print from my macbook.
It has worked before but after moving house/network I am having problems.

Here is what I have done:
Printer setup with cups ubuntu desktop computer name 'hal' (192.168.2.5)

web interface on http://hal:631 works fine and can print a test page

adding a printer with ipp protocol on macbook with address 'hal' says "valid and complete address"

using driver 'hp psc 2100 series' which has worked before and the printer is an hp psc 2100.

Printer appears in the mac 'Print & Fax' dialog as 'Idle'

I send a document to the printer and it always ends up paused and no amount of 'resuming' will help.

The mac 'printers.conf' is as follows after attempting to print:
# Printer configuration file for CUPS v1.4.7
# Written by cupsd on 2011-09-23 10:33
# DO NOT EDIT THIS FILE WHEN CUPSD IS RUNNING

There is nothing new in the error_log or the access_log on the desktop 'server'

Thanks for any suggestions
George

One day I found this command:
which tells zeroconf utilities to allow browsing and detecting remote printers.
source : http://www.cups.org/documentation.ph...5/sharing.html
I run it again any time network printing stops working.

Thanks for suggestion.

However it made no difference.

Cheers
George
