picture printing software for 3×3, 3×4 etc etc

Wifes looking for some free and hopefully easy software for printing home photos off in various sizes, have windows 10 and the photo wizard sizes are limited , ie no 3×3 etc ? ..
any recommendations ?

Whst printer/model are you using?

epson sx420w

Re install your printer software as Epsons own is capable of printing up to A4. When reinstalled print from the computer to choose your sizes and layout.

downloading may give you a more up to date version

Epson software only has set sizes, so still no good !
Just used easyboot photo print , works a treat :)
