I have a HP Photosmart 8450 printer. I would like to know how to set it to print 8.5 x 8.5 photos

Hello SLeolioness

Please, go HERE for HP's support page for your printer.

HERE you will find the manuals that are available for your printer.

You can change the photo sizes on the front control panel. Please, go HERE and scroll down to the HELP section. [ Photo sizes ] is on the 3rd row.

I think that may be it because if you go further down to the PREFERENCES section, you'll see an option there for printing Passport Photos.

While still in preferences, look at the 5th row from the bottom. There you'll see how the printer can automatically detect the paper size.

In the 4th row from the bottom, it explains how a print preview option can be set. In this way, it will allow you to preview the photo(s) your about to print in the selected layout. (Not an option on all printers, however.)

So, it would appear that by using the proper combination of tray size, paper, and menu selection (for the photo size) you will be able to print to 8.5 x 8.5 photos.
