- semireg 3y agoAn hour to a few days. Sometimes a week of back and forth to 1) make it work, 2) make it work right, and 3) make it work fast. Many times there’s a PDF for the printer “language.” Think ZPL or TSPL. But even then, each printer has quirks (two incompatible settings) or a setting that’s unitless (dots? mm?) and the best way to nail it down is by using a USB sniffer, capturing the commands, and then implementing similar custom controls and logic in the app.
