ZPL Printer Set up on Raspberry Pi for Barcode Scanners - Knowledge of ZPL, Debian/Raspbian or Linux, as well as basic IP connectivity.

Running a small system of ZPL Printers connected to Raspberry Pi and barcode scanner. Looking for assistance to finish set up. Simple for anyone with knowledge of Zebra ZPL and Raspberry Pi or Debian/Linux. Will just require assistance via SKYPE, or Zoom etc, to be able to configure the Zebra and Pi connectivity, and the correct printing of labels via barcode scanner. We have 2 working systems all good, but have problem setting up the 3rd small system, as the colleague who set the original 2 systems passed away late last year. Any help appreciated. Thanks in advance.
