Printing issue with SA 20X
You must use the Entomed Printer Interface cable, SA07, part number EN200907 when printing to a printer.
This interface creates the image that is printed so a normal serial to USB converter will not work. That only works for transferring to a PC.
However, there might be some issue with some printers that say that they are PLC5 compatible but are not fully compatible.
Most of Lexmark and Brother printers work fine, but some models from HP could have problems.
