Printing odd sized photos

[Staphylococcus]

Hi all,

I need some info on how to print odd sized photos. Examples are like I want to print 2x5 or
5x5 or 3x7 inch sizes. As I only want to print a few of these images at this size, most of the software only allows 1 odd sized print per page or all the same size per page. Like that a bit waste,right? Is there a software that can mix n match odd sizes for printing?

Can anybody help in providing a better solution to my problem? THanks
