There could be various reasons as to why your printer is not printing. There are two ways in which you can test to see what the problem is.
Firstly, try printing a test page on the TallOrder Point of Sale. If this does not yield any results, then try and print a Windows test page.
If the problem continues and you are still not able to print, please contact email@example.com or call +27 (0) 72 863 0116
