LPRng: HP Color LJ 4500 blank pages

[Dan Kirkpatrick]

All of a sudden most of the time people print to a HP Color LJ4500DN, it just keeps printing blank pages... the only way I can get it to work is turn it off, turn it on, reset the queue, and maybe it prints then... just to repeat again. LPRng and printcap entry havent changed, samba has recently been upgraded, but am not sure if it coincides.

I've set the idle-timeout on the printer to 1200 sec to avoid the long warmup problem, but that gets reset to 90 every time the printer gets turned off.

They're printing through samba-2.2.7a-1 and LPRng-3.6.26-1
I'm not sure I understand all of the extra settings for waitend interval, rw_timeout, socket linger...

Any suggestions?
Thanks!

Here's the printcap entry for the printer:
