You can have the driver send a command every time a document it printed.
The command to enter  is:   1B 70 00 C8 FA

Using the Send command as on option will generate a 200ms pulse to the cash drawer #1 line.

Note: Do not connect a Cash Drawer to the POS108 when using the Printer Alarm setting
as the alarm will not sound.

Select Cash Drawer    

Now you will see

Cash drawer #1 (2 Pins) and Cash Drawer #2 (5 Pins)
If you only have 1 cash drawer, use drawer #1
Each drawer has these options:

  • Do not open (Do not send command)

  • Open before printing

  • Open After printing

Select Open before printing or Open after printing to have Windows issue the open drawer command every time a document is printed.
