Canon Pro-100 Custom Paper Size
« on: November 07, 2018, 09:47:55 am »

I'm documenting this to possibly prevent somebody else going down the same rabbit hole.

My 17" printer died, leaving me a box of 17"x25" semi-gloss paper.  I checked the custom paper size limits in the Pro-100 printer driver, stated I could go as long as 26.61 inches.  So I did the obvious, trimmed 4" off of a sheet of the paper, ending up with a 13" x 25" portion. 

Found an appropriate image, set up a custom paper size in the Pro-100 printer driver, 13x25, and hit the print button.  Started up ok, but before actual printing commenced the driver threw a message, paraphrased, illegal media type and paper size combination, change one or the other and try again.  Same result for both the rear tray (sheet feed capable) and manual feed tray.  I tried several media types, same message.

After some head scratching I found the following buried deep in the bowels of the online manual:

You can print on non-standard size paper within the following ranges.
 rear tray
- Minimum size: 3.50 x 5.00 inches (89.0 x 127.0 mm)
- Maximum size: 12.95 x 26.61 inches (329.0 x 676.0 mm)
 manual feed tray
- Minimum size: 8.00 x 10.00 inches (203.2 x 254.0 mm)
- Maximum size: 14.00 x 23.00 inches (355.6 x 584.2 mm)

Sure enough, after defining a custom paper size of 12.95" x 25" I was able to print my image thru the rear tray.

Any theories as to the origin of this constraint?
