label-ops
Print labels and receipts that actually scan — ZPL for Zebra label printers, ESC/POS for 58mm Bluetooth thermal printers, and barcode check digits that a scanner accepts. Use when the user mentions ZPL, Zebra, thermal printer, label printer, receipt printer, ESC/POS, Web Bluetooth printing, TCP 9100, Browser Print, shipping or asset labels; when a barcode scans as the wrong number or not at all; when a label prints blank, clipped, at the wrong scale or with garbled accents; or when computing EAN-13, UPC-A, ITF-14, GTIN, Code 39, Code 128 or GS1-128 data.
