How to install Zebra label printer with RS232 port under Linux.

In this tutorial I’m using Zebra LP 2824, but it should also work with other Zebra printers. What You should have:

  1. Zebra printer
  2. USB-COM (rs232) adapter ak7tb9

This method is universal and it should work on all Linux based systems. Connect USB-RS232 adapter to printer, and connect USB plug to Your computer. Now open terminal and type:

dmesg

You should see sth like this:

ch341 2-1.4:1.0: device disconnected<br />usb 2-1.4: new full-speed USB device number 7 using ehci-pci<br />usb 2-1.4: New USB device found, idVendor=1a86, idProduct=7523<br />usb 2-1.4: New USB device strings: Mfr=0, Product=2, SerialNumber=0<br />usb 2-1.4: Product: USB2.0-Ser!<br />ch341 2-1.4:1.0: ch341-uart converter detected<br />usb 2-1.4: ch341-uart converter now attached to ttyUSB0

As You can see, my device have been installed as ttyUSB0 port.

Next step is simply adding printer to Your system. Most universal way, to do this is through CUPS browser interface. Open Your browser and go to page http://localhost:631/ and click on Adding Printers and Classes
