Can we be clear here: you are running an up-to-date Wheezy?
Please do the following:
1. Enable debugging with
cupsctl --debug-logging
2. Empty the log with
echo '' > /var/log/cups/error_log
3. Restart cups
service cups restart
4. Print and then print again (the second print will presumably fail)
5. gzip error_log and send it here.

The printer should be restarted, but doing all three will do no harm.
Sticking with a possible USB issue: see if what is in bug #697970 helps.
