Printing problems - Gnucash 2.2.1/MacOS 10.4.10

[Henry M. Benson]

Hi,

I'm having trouble printing reports or checks using GnuCash 2.2.1/MacOS 10.4.10,
installed via MacPorts.

I get the print dialog, select a printer (I have three; it doesn't matter which), and
I get a popup box titled "Error Printing" that contains only "successful_ok".  After
a few tries the text turns to "too many failed attempts".

Some debugging, googling and poking at cups yields a possibly-offending line
in /var/log/cups/access_log:

localhost - - [24/Aug/2007:16:28:16 -0400] "POST /printers/EPSON_Stylus_COLOR_860 HTTP/1.1" 400 0

which if I'm correct means that GnuCash is trying to print a zero-length file, resulting
in a "Bad Request" error from the POST.

Any suggestions on where to go next?  I'm unix-literate but not familiar with
the printing stuff.

btw I couldn't print in 2.2.0 either, but I upgraded to 2.2.1 before starting
to debug.  1.8.<latest> with MacOS 10.3.<latest> worked fine on the exact same 
hardware, if that means anything.

Thanks,
Henry
