Tale of two error_log files (from directory /var/log/cups):
[cups 1.1.x, that's what it says on the test page, but it may be 1.3.9]
I [04/Feb/2012:06:08:25 -0800] [Job ???] Request file type is application/postscript.
I [04/Feb/2012:06:08:25 -0800] [Job 1396] Adding start banner page "none".
I [04/Feb/2012:06:08:25 -0800] [Job 1396] Adding end banner page "none".
I [04/Feb/2012:06:08:25 -0800] [Job 1396] File of type application/postscript queued by "root".
I [04/Feb/2012:06:08:25 -0800] [Job 1396] Queued on "iP1600" by "root".

[cups 1.5.0]
(no error_log entries for test page)
[page_log]

[access_log]
localhost - - [04/Feb/2012:06:06:21 -0800] "POST /printers/ip1600 HTTP/1.1" 200 446 Print-Job successful-ok

Does this seem right?  Am I giving you clues?

Thanks again.
