multiple paper sizes at the same time?

[rocketman766]

I am new to the forum here, so forgive me if this question has been answered here already. I looked thru the threads but did not find my answer. I would like to know if there are any dye-sub printers that can print 4x6 and 5x7 and possibly even 8x10s without having to change out the paper and rolls for each size? I understand that I could print all of them on a 8x10 sheet and then trim, but that would not be economical for me.

My use will be for onsite printing where I offer all three sizes listed above to be printed while the customer waits. I currently have to use 3 separate printers loaded with all three sizes separately. I am not against using an ink jet printer if someone can recommend one that holds the different sizes listed above at the same time.

Thanks in advance.
