/**
 * Zebra Printer Compatible Fonts
 * 
 * This file defines fonts that closely match Zebra printer output.
 * Zebra printers use CG Triumvirate (similar to Swiss 721/Helvetica).
 * 
 * Font Priority:
 * 1. Liberation Sans - Free alternative to Helvetica (GPL license)
 * 2. Helvetica Neue / Helvetica - macOS/system fonts
 * 3. Arial - Windows system font
 * 4. sans-serif - Browser fallback
 * 
 * To improve accuracy, download Liberation Sans fonts:
