Photoshop And MG5320

Hello everyone. Cross post from my Adobe community post, which got absolutely no posts whatsoever; I am having a very frustrating problem with Adobe Photoshop Elements 10's printing function. I am trying to print a DVD cover (On my Canon MG5320 printer), as I've done many, many times.

The problem: It suddenly decided that it didn't care one little bit about what custom size I tell it, It isn't going to print it.

I typically print at 184.5mm tall, by 275.8mm wide, And it suddenly decided that instead of leaving a strip of white paper to cut off on the right side (Letter sized Canon photo paper), it would fill the entire paper with it, minus an extremely narrow unprinted strip on the left.

I tried entering a smaller print size, and it had no effect whatsoever on the outcome. The only way I can make the print smaller is by actually UPPING the custom size in Adobe. When I do that, however, if I unclick 'Center photo' as I usually do, it cuts off the right side of the print.

It's all very confusing, and this happened once before, but it randomly went back to normal.

Borderless printing is on, as usual.

Thanks so much for any help; It is very frustrating and confusing.

What OS are you using?

Did you try rebooting everything? Re-installing the print driver?

I may be way off here... but when I'm using photoshop to create a cover image, for facebook, I always forget to change the crop measurement to pixels. This makes the image very large, because I've unknowingly told it to make the image something like 8xx inches long. I realize the problem because of the file size or how long it takes to actually crop it.

Anyway, I think of this because I'm wondering if your dimensions got changed from mm to cm or inches or something like that. I have no experience with Elements, or printing DVD covers, so I could be wrong.
