Printing custom paper size on Pixma Pro 100

[aajax]

Having done this before I'm pretty sure what I'm wanting to know is documented but I'm afraid I cannot find it now. I have purchased a roll of 13" wide paper in order to print sizes different than 13x19. As I recall, Borderless printing is NOT supported but there are limits on margin sizes that are defined. I typically make my image files sized to fill all of the available space on whatever paper I'm using.

Can someone refer me to the documentation that states the image size limits when using custom paper size?

I think the paper normally needs to be fed in portrait orientation.  In that, width of feed tray set to narrowest dimension.  If the custom size is 13" by something smaller than 13" is that still true? Are there limits on the paper widths that can be fed to the printer? Maybe they are different for Rear Tray verses Manual feed?

Paper is required to be fed in the portrait orientation. When selecting custom sizes enter 12.95" not 13". Prescribed margins are shown in the On-Screen Manual.

If I'm using paper from a 13" wide roll and that is the width (i.e., narrower side) does that mean I should subtract the .26" (i.e., E + F) from 13 or 12.95 when trying to size my image to use all of the available space?

Also, regarding image length (i.e., longer side). I'd expect to add the 2.92" (i.e., A + B) to the image length when measuring the length of the paper to be cut from the roll.  Yes?

Thank you.

That second page is what I've previously referred to but couldn't find.  I was thinking I should be able to find it by looking through Table of Contents.  However, it looks to me like you performed a keyword Search.  That may be the lesson learned from this experience.  In that, using the Search method may be better than searching on my own.

If you don’t want too lose any part of your image you must size it to fit within the printable area. If you are using Fine Art type paper you would use the A+B margin. For all other papers you can use the C+D margin. 
I use a standard 0.5” margin for all paper other than Fine Art.

One of my goals is to produce an image file that the printer driver will print without altering (i.e., scaling) my image.

Then there is the need for me to be able to correctly size the paper which in this case I hope to limit to cutting a piece from the 13" wide roll that is the correct length..
