Thanks for the suggestions Roy.

The image is vertical 15" wide by 58" tall and I have the paper size 
set to 24" wide by 60" height. Good idea though. I didn't know that 
Landscapes required more resources to print.

It was interesting reading the CUPS Error Log. The Quad9600 print jobs 
showed no errors in the log, but they stop at 16" every time. Here's a 
sample job:

I [08/Aug/2004:13:24:43 -0400] Adding start banner page "none" to job 
667.
I [08/Aug/2004:13:24:43 -0400] Adding end banner page "none" to job 667.
I [08/Aug/2004:13:24:43 -0400] Job 667 queued on 'Quad9600' by 'toles'.
I [08/Aug/2004:13:24:43 -0400] Started filter 
/usr/libexec/cups/filter/cgpdftoraster (PID 1657) for job 667.
I [08/Aug/2004:13:24:43 -0400] Started filter 
/usr/libexec/cups/filter/quadrastertoprinter (PID 1658) for job 667.
I [08/Aug/2004:13:24:43 -0400] Started backend 
/usr/libexec/cups/backend/usb (PID 1659) for job 667.

The following two error messages popped up a few times:

E [08/Aug/2004:13:32:06 -0400] [Job 668] Unable to get media size!
E [08/Aug/2004:14:00:48 -0400] get_printer_attrs: resource name 
'/printers/øˇÕp' no good!

I'm not sure if this means anything, but compared to the Epson driver, 
Gimp is painfully slow printing. Great quality, but slow.

All the best,

John
