Comment 8 for bug 1323040

I tried the HP customer support fax line (Send a one page black and white text fax to 1-888-hpfaxme (1-888-473-2963).
    When your fax is received by the HP Test Fax Service, we will generate a return fax to you within five minutes confirming that we received your fax. This verifies that you can both send and receive a fax with your fax machine.) and it hung without sending.

I checked CUPS and the jobs were pending without actually sending. I cleared my syslog before trying anything and it's just a blank document now.
