Make sure that your printer is connected, powered on and set up per the instructions here. Then confirm that the cash drawer is connected to the printer via the cable that came with the drawer.

Open System Preferences (accessible via the  menu in the upper left corner of your screen). Click the "Print and Scan" icon, then click the "add" button as indicated below.

STEP 3

The "Add Printer" window has a list of printers currently visible to your compute. Choose the Star printer from the list.

STEP 4

Choose a name for the printer if you like, make sure Print Using is set to "Star TSP100 Cutter," then click "Add".

STEP 5

In your preferred web browser, go to the address "localhost:631". From there you can access your printing utility known as "CUPS". Click "Administration."
