What are the differences between the printers? The 37e series of printers were made for small production run companies. The 37e can do 2 lines of print, the 37e+ can do two lines of print faster than the 37e and has a RS-232 interface and the 37ez can only do 1 line of print. The printers are not made anymore by the OEM, Though there are still many out in the field. They were the first low end series of printers from the OEM that used 24Vdc control. They were also designed to use less air for the printer from previous units
