How to suppress printing (Silent Printing)
Getting annoyed with having to click print for every receipt? Use these browser settings to skip the print dialog box.
Chrome (PC):
Right click the Chrome icon on your desktop (or find in your start menu and right click).
Select Properties .
In the Shortcut tab, place your cursor at the end of the existing text and type “–kiosk-printing”.
Click OK to save.
Change Firefox (browser) settings to automatically print:
Open Firefox and put about:config in the address bar and click Enter
Type print.always_print_silent in the filter box at the top - if you have an entry already there and it is set to false, right click it and choose ‘toggle’ to set it to true
If you don’t have an entry already there, then you will need to right click the screen and choose New->boolean
Enter print.always_print_silent as the preference name when asked and click Enter
Set boolean value to true and press Enter
Please note that the browser will try to print using the last printer you used when you had the dialog box open.
