To verify that the correct printer driver is being used

When the Datamax MK III printer is installed, Windows may assign it the wrong printer driver, causing ShipAccel to be unable to print. Follow these steps to ensure that the correct driver is being used:

1. View your printers:
   • Windows 8 or above: Right-click on the Windows Start icon and select Control Panel > Devices and Printers.
   • Windows Vista or 7: Select the Windows Start icon > Devices and Printers.
2. Right-click on the Datamax MK III printer and select Printer Properties.
3. In the Printer Properties, select the Advanced tab and look at the Driver menu:
   • If the driver is Datamax MK III​, the correct driver is being used. The installation is complete.
   • If the driver is not Datamax MK III​, select Datamax MK III​ from the Driver menu. If Datamax MK III​ is not listed in the menu, this means that the printer driver for the Datamax printer has not been installed. Install the driver as explained above.
   • If the driver is Pitney Bowes 1E26, follow these steps to remove the Pitney Bowes 1E26 driver from your computer:
