Loop Items in Queue#787

We print sets that are ~15 plates for one single item fairly often. An option in the print queue to mark a set of prints to loop would be helpful.

IE, print 1-15 then print 1-15 again.

In order to keep things organized, you currently have to upload the same files into the queue as many times as you need the copies. If I need 1 set printed 5 times, you can’t just put quantity of 5 on them because 1) if you don’t have 155 available printers you end up with 15 incomplete sets until all 155 prints are finished and 2) when removing items from the printers each set is spread out all over the building instead of keeping each set localised to the closest printers
