printer fails with kernel error



I have fc10 with a HP lj2100 connected to the box
yesterday I began having kernel failures related to printing
I can print a text file from the console using lpr
I can print a test page from the system/printer/properties dialog
I can print this message from the mail client
There is another box connected by network; it has intermittent failures
sending filesto the cups queue
I have been gettingdialogboxes popping up sayingrinter may not be
connected, and kernel failure messages as follows
any help would be appreciated
TIA
