I've installed my HP Photosmart D5160 on my Win7 HP x64 rig. No issues with normal printer. Tired printing a DVD today through Surething and that worked fine, though I'll need to adjust positioning to center it better. I tried to print the insert and ran into issues. Evidently I cannot input a custom paper size for some reason. The option is there but when I create the custom size and save it I can never actually use it. It does not appear in the list at all and the printer just defaults back to Letter size when inputing the custom sizing. Anyone have any idea how to fix this?
