How do I open my printer driven Interface Cash Drawer?

MMF Cash Drawers that connect to a receipt printer, require the POS application to send the proper opening codes to the printer, which will then send the signal to open the Cash Drawer. Consult the software documentation for your particular printer for the proper open codes.
Typically the open code is placed in a field or series of fields under a Configuration, Utilities or Setup portion of a POS application. For example, with an Epson printer the following code would be entered in your printer setup.

ESC P m t1 t2
Generate Pulse Drawer 1-0 On Time Off Time
    Drawer 2-1    
(Hex) 1B 70 0 5A 28
(Dec) 27 112 0 100 40

For more information on open codes, consult the documentation or manuals that came with your printer.

Does it matter which end of the Printer Cable Assembly plugs into the printer and which end plugs into the MMF POS Cash Drawer?

Yes. The correct ends must be plugged into the receipt printer and cash drawer. The end of the cable that has a label with the cable part number will plug into the Cash Drawer. For example the end that reads:  226-199EPST10-00 would plug into the Cash Drawer and the end that has a label that reads: “Connect to Star Printer” would plug into a Star receipt printer.
