First step is to make sure that the device can see and talk to the printer. This has nothing to do with the OperationsCommander commander and can actually be setup before installing the software.
Once the operating system sees and connects to the printer OperationsCommander can use that printer.
Make sure Bluetooth is enabled on your device. Tap on Bluetooth to get more options.
Select the option to Search for Devices.
Your printer should appear in the listing.
Tap on the printer to pair/link your printer and tablet together.
Type in the printer PIN if your printer requires one.
If asked for the Printer Pin the default Bluetooth PIN is usually 1234 otherwise please consult your printer manual.
