A more robust printer compared to the M4, Q4 thermal printers provide a faster output and increase sheet capacity. Q4 is ideal for high traffic stores that print large quantities of 4″x6″ photos as well as 6″x9″ photos.
The Q4 thermal printer produces 50% more prints per ribbon and paper roll compared to the M4 — requiring less maintenance time. Additionally, when combined with multiple Q4 printers for single order processing, it prints at speeds up to 2.8 seconds/print.
