”4×6” setting was missing in printer settings for photos.
When opening the print settings the option to check ”Fit to Picture Frame” and ”4×6” settings were not there.
Re-installing the Driver would fix that setting.
Google the Driver for that printer name and look for the download on the manufacturers website.
Example: HP LaserJet Pro P1102 Printer series Driver
You can also try to update the Driver from the Device Manager.
