CUPS "Unable to add document to print job"

[Timothy Murphy]

My network printer - a Samsung CLP-325W - has stopped working
from my Fedora-17/KDE laptop.
I've tried both the Samsung Linux Unified Printer Driver, 
and the foo21pdl driver.
In both cases I get the error
-------------------------------
E [06/Sep/2012:12:39:38 +0100] [Job 37] Unable to add 
document to print job
-------------------------------
in /var/log/cups/error_log .

The printer is seen by CUPS.

I've googled for this, and it seems a common problem;
but I haven't seen any mention of what the error means,
or what one can do about it.

The printer is working fine, since I have Windows XP on this 
laptop,
and have no problem printing from that.

I wonder if anyone else has encountered this problem,
or can suggest how to resolve it?
