LP2844 Label Printer Overview
The Zebra LP2844 thermal label printer is a good addition to any electronics lab. It is really easy to print labels for component drawers and projects. It is a 4″ model that can print shipping labels too, great for Ebay. The 203DPI print head is adequate to print labels, although there is some blockiness to them.
I use LaTex to print labels using the geometry package to change the page size. The code for this can be found here.
In this video I teardown the printer to see what is inside. I also go through the installation steps for Linux Mint KDE 17.1. At the end of the video, I do a quick demonstration.
