From Zebra Printers How to install GX420d shipping thermal label printer

Open System Settings > Printers

Click +Add

Set up the printer/port settings:

For USB Printer:
Enter URI
Enter Device URI: usb://Zebra/LP2844 (example)

Get this port by issuing the command:

 lpinfo -v |grep

Note: You don't need the "? location=1a200000" information.

For Network Printer:
Devices: AppSocket/HP JetDirect
Host: (example)
Port: 9100

The Host IP address may be configured to use a different address, which is outside of the scope of this tutorial. If AppSocket is not listed, close and relaunch the Wizard and it should appear.

For Serial Printer
Devices: Enter URI
Enter Device URI: serial:/dev/ttyS0 (or serial:/dev/ttyUSB0, etc)

For USB serial, issue the command:

dmesg |grep tty
    Insufficient permissions

fix: This command grants the logged in user write permission to all serial ports:

sudo usermod -a -G dialout $USER;
    Note: 12.04 users may also need to remove [ModeManager]( due to a specific bug, ttylUSB devices don't seem writable by CUPS, so try:


Click Forward
Driver: Select printer from Database > Generic > Forward
Models: Raw Queue
Drivers: Generic Raw Queue > Forward

Note: Some print drivers, such as Zebra ZDesigner or CUPS Zebra driver have dual-mode drivers capable of accepting Raw commands as well as PostScript commands. If Raw printing works with the vendor supplied driver, chose that over the Generic/Raw driver.

Printer Name: (ie: zebra)
Description: Raw Zebra Printer
Location: Ubuntu PC

You may now print to your printer.
Looking forward to hearing from you,

How am I doing? Email supervisor, P.Manickam with any feedback

I pasted the complete install from Zebra in case someone else need it in future. Model GX420d is a very popular model. I did not know how to paste the images in so pasted the path. Can someone fix that part.

I can follow some of this but not knowing Zorin/Linux will need help I am sure.

I modified your post so that it correctly displays the images. Could you tell us the issue that you're having and how could we help you with it?

The issue was the GX420d would not print. I followed her instructions and with a little guess which out of four models listed would work I chose ZPL. It prints the shipping label correctly but is only 2 11/16" x 3 15/16" and should be about 4" x 6". I will send her an email on how to enlarge the print out.
If anything was going to prevent an office switching to Z16 Pro it was the Zebra printer. I am delighted it looks like the switch will be coming sooner than expected. WoW

Opened up the printer settings and changed the size to 4x6 works perfectly

I modified your op using markdown and adding space to make it more readable.
