Is the printer driver for your printer installed?
When downloaded from the Website, P-touch Editor and the printer driver are separate files. Be sure to download and install both P-touch Editor and the printer driver from the [Downloads] section of this website.
Your printer may not be the default printer for P-touch Editor.
In P-touch Editor, click on [File] and select [Printer/Page Setup] to display the Printer Setup dialog box.
Check that your printer is selected. If not, select it and click the "Save Current Selection" button.
If your printer is listed under "Other Printer", the printer driver has not been installed correctly. Try installing the driver again.
