LAN/WiFi Network Setup #
Make sure that the Datecs fiscal printer has internet access and is connected via LAN or WiFi to the same network as the MobiRest Business application. It is also important that both devices are on the same subnet — for example, if the MobiRest application is running on a device with the IP address 192.168.1.x, then the Datecs fiscal printer should have an IP address in the form of 192.168.1.y, assuming a subnet mask of 255.255.255.0. This ensures proper communication between the two devices over the local network.


Important: These instructions provide a general guide. The exact names of menus, button presses, and options may vary slightly depending on the specific model of your printer. Please refer to your printer’s user manual for the most accurate information.
