Pixma iX6820: How to print custom sizes?

[skippyphoto]

Please Advise. When trying to print a custom size paper I cannot select a custom size from the print dialogue box. How do I print a custom size? Desired size is 2.5 x 3.58 in. This is beyond frustrating.

Reinstalled drivers today trying to resolve with no change. I can select custom in the system dialogue box but in never seems to translate to any of the application print dialogue boxes (Photoshop, word, print pictures etc.)

Images are too small for me to read, but I think i understand the issue.

The setting doesn't work "backwards" to printing applications.

You would specify the print size in the app and then set the printer driver to that custom size. Not all printing applications will let you specify a custom size.

I came up with a little hack.  I stick my cardstock onto an A4 paper and it tricks the printer into thinking that I am printing on an A4.  You have to know where your image is going to be printed on that A4.  I'm using photoshop so this is what I do.  First, I print my image on a normal A4.  Then I stick my blank cardsock on top of the image on that A4 (with a gently tacky double-sided tape), and print again.  This is not perfect and needs "a lot" of finessing, but I think it is better than no result.
