The Canon Pixma Pro-100 is one of photographers' favorite printers, and a good number of members of CCC own one. However, few of those who own this printer realize that it can be used to print panoramas up to 26+ inches long. Also, there's a little-known trick to getting this printer to accept "custom" paper sizes.
This printer will accept paper up to 13 inches wide, and paper 13 by 19 inches is the largest size listed among the choices available in the list of paper sizes that appears when setting up to make a print. To make a print longer than 19 inches, you have to first be sure that “Normal Size” is selected in the Page Layout dialog box. Only then can you select the "Custom" setting in the Page Size dropdown menu.
For a good video on how to use the custom setting, go to https://www.youtube.com/watch?v=1oUX2goq-W4. However, this video doesn't say anything about finding paper of the correct size or how to avoid a common error in setting the custom size dimensions. (See red text below.)
I chose Red River's UltraPro Satin paper sized 17 X 25 inches and simply cut the paper down to 13 inches wide. An alternative would be to buy a pack of their 13 X 38 if you want to go up to the maximum 26+ inch limit on the printer. (The cost of each choice is the same.) Second, when you go to set the custom paper dimensions (described in the video), you must set the width to 12.95 inches, NOT 13 inches--even though the paper is, in fact, 13 inches wide. This is the "trick" mentioned above. (The length can be set up to the maximum allowed by the printer.) Note: Don't be confused by the printer dialog using the term "width" for what you may think of as the height in a pano!)
Anyway, I wish you well in trying this, and if you have any difficulties, let me know and I'll try to help you through them.
