latest client update killed printing

[william at fragakis.com]

Hi,
I ran yum update yesterday in my client chroot and something has killed
printing to clients (separate clients with different printers). Cups
reports:
"recoverable: Network host 'ws152' is busy; will retry in 30 seconds..."

printers are set up via app socket/jet direct socket://client:9100
I've seen this error before when the printer_0 setting wasn't set
correctly in lts.conf. (yes, it worked before and I've checked the
settings)

No changes were made on the server, just the client chroot. Additionally,
reverting to an earlier image before the update restores
printing. I encountered this issue with a second server, too, that had
just run an update.

My last update included the following packages:
