Under "Printer Properties" of the printer, click on the "Printer Commands" tab.
In the box to the right of "End Print Job" type the following string of code in:
| <0D0A1D>VB<20> |
The "0" are the number zero, not an uppercase alpha O.
The less than and greater than symbols are located over the "," and "." on your keyboard
After entering the above string click on the "Apply" button in the lower right corner of the properties screen. Now each time a ticket is printed, the paper cutter will cut through 90% of the width of the paper.
