I also posted this on the DPR forum.
I am trying to print a 16x24 photo on a sheet cut from a 17 inch roll of photo rag. So I cut a sheet 26 inches long.
I go to page set up and then manage custom sizes. I add a new custom size of 43.2x66 cms (which by my calculation is 17x26 inches). I resize my picture. I go to page set up and choose my new custom page size. Print with preview shows me what I expect - i.e the picture centred in the sheet with small borders.
I go to print the thing and the first time I get a small rectangle of about A4 size in the bottom right of the sheet before the printer spits the rest of the sheet out. I restart the computer on the basis that there might have been a spooling error. Having been left with 3/4s of a sheet of photo rag I cut it down to about 17x16 inches.
I set up a new custom size page of 40x40 cms. Resize another picture to 38x38 cms and try and print that. This time it prints the length of the picture but cuts off about 1/3rd to the right hand side.
The printer has been behaving impeccably with A4, A3 and A3+ sizes. So presumably it is something that I am doing.
Anyone successfully set up a custom page got anything to say that might help?
