Setting up Secure Print

Secure print will be required starting in October 2022. In order to use the STAR WebPRNT direct print functionality, secure print must be enabled after this date.

Secure print is only available when using WebPRNT. WebPRNT is the only direct print option available to send receipts to your Star receipt printer without any dialogs displaying.

In order to use your printer in secure print mode, you will have to follow these steps in order for your device to "trust" your printer. You will log in to your printer over the network, create a certificate, then import that certificate into your device.

First, make sure your printer is connected to your network and you know the IP address of the printer. To get the IP address, turn off the printer, then hold down the paper feed button while you press the power button once to turn it back on. The printer will print out the IP address of your printer at the very end.

Next, make sure secure print mode is enabled. Open the POS Register (Point of Sale >POS Register), click on Printer Settings (1), make sure Star WebPRNT is selected, then enable the Secure Print toggle (3) and click Save.
