partdb-labeler 0.2.2

PartDB Labeler

partdb-labeler

Connects to a PartDB server, grabs info for a selected part, and formats a label to be printed on an EPL2-compatible label printer. Command-line options enable configuration of the label size, server to use, and more.

Why did I write this?

PartDB has a label generator built-in, but it only produces PDFs that must then be rasterized and printed. This works well enough if you're sending labels to a laser printer, but I found that QR codes small enough to fit on the label stock I wanted to use weren't scannable. This generator speaks EPL2, one of the languages used by Zebra label printers, to produce precisely-formatted labels with QR codes that scan easily with your phone or a dedicated barcode scanner.

Compatibility

So far, it's been tested with two Zebra printers: an LP2844 and a GK420t. The LP2844 was driven by an Arch Linux system with a CUPS print queue feeding it through a network print server. The GK420t was driven by a Windows 11 system, connected to the printer via USB.

Usage

partdb_labeler -h will show you the available options.

For convenience, you might also consider adding a short shell script somewhere in your PATH that will call the Python module with your server configuration. I use this (the API key is a read-only key I've publicized elsewhere):

#!/usr/bin/env bash
partdb_labeler -p https://partdb.alfter.us -k tcp_673fc81f0b7837ca4c029fbd6536b27742eb8b742eba27bf547c8136dc6a84f8 $*

or the same, as a batch file on Windows:

@echo off
partdb_labeler -p https://partdb.alfter.us -k tcp_673fc81f0b7837ca4c029fbd6536b27742eb8b742eba27bf547c8136dc6a84f8 %*
