HP Color LaserJet Pro M452nw Manual Duplexing doesn't line up

[cuelliam]

HP Color LaserJet Pro M452nw does not support auto duplexing, but I can MANUALLY print both sides of an 8.5x11 by reinserting paper after  printing the first side.  I design greeting cards, and need to print both sides of a 9.25x6.25 sheet of paper, but no matter what setting I use, the entire image on both sides runs off the page. I am using inDesign CS6 on a Mac OS10.10.5 Yosemite, and have attached screenshots of the print dialog screens. Have tried all combinations of print settings, page position, paper size, and I still cannot get front and back to line up, or print completely on the page.

Do you have the paper settings on the printer itself set for that size? If not, the printer is likely trying to print on A4 or letter size and shifting the image. You need to set the paper size on the printer to 6.25 x 9.25

Hi, thanks for the quick reply. The printer (hardware) setup  only has 3 options, letter, Legal, A4. The software allows custom sizes, but  I can't see a way to change the paper size on the printer itself?
