This article covers the scenario when Rollo was working properly before, it is showing a green light, and no label advances when you click "Print." 

The most likely reason is that Rollo is connected to a new USB Port. Windows will register Rollo as a "new" printer whenever the USB port changes. Thus when you print to the "old" printer, it simply keeps it in the print queue. 

This happens so that you can run multiple Rollo printers from the same computer, each with different label types and settings. 

How to fix:

  • Open your Control Panel -> Printers and Devices and note which Rollo Printer is "active." It may be the Rollo Printer, the Rollo Printer (Copy 1), or the Rollo Printer (Copy 2), etc.
    Be sure to print to the same active printer name when printing.
  • Alternatively, please unplug and re-plug Rollo into the same USB port as before and that should restore your printing without further changes. 

If Rollo is flashing red, please see this article.

If Rollo is printing blank labels, please see this article.
