Printing fails in 10.1 - Odd Console message

[genghiscohen]

My Canon BJC2100 has been working fine ever since I installed 10.1. Now suddenly I can't print any more.
Print Center launches and says it's opening the printer connection, but never finishes. I get the following message in the Console:
Oct 15 21:03:23 localhost lookupd[189]: DNSAgent: dns_send_query_server - timeout for 24.48.40.2
Sounds like Print Center can't communicate with the printer for some reason. Anyone have any thoughts and/or suggestions?

Update:
When I started up my iMac this morning, I was able to print. But after I logged out and my wife used the machine for a while, printing is again disabled.
Oh well, at least I'm getting a new error message in the Console:

BeginJob: [ErrCode=-9589] Couldn't retrieve value for PMRM:BeginJob:E_STAT=-9589

*** CFLog (20): /Applications/Utilities/Print Center.app/Contents/MacOS/Print Center[1510] Printer Error: An Error Occurred while Printing
