Store description excerpt
The field toolbox for ESC/POS thermal receipt printers. Find, test, and fix any network receipt printer from your phone — no laptop, no vendor utility. FIND — scan your WiFi for printers on port 9100, save profiles, or add by IP. TEST — one-tap test pages: status, font & style matrix, barcode + QR, 58/80mm ruler. FIX GARBLED TEXT — the Codepage Matrix prints the same sample under every common ESC/POS codepage (incl. Big5, GB18030, UTF-8), each labelled. Find the row that prints correctly, set that codepage in your POS, done. CASH DRAWER — fire the kick on pin 2 or pin 5 with selectable pulse widths; wiring explainer included. LOGOS — pick any image, preview true 1-bit dithering (Floyd–Steinberg / Bayer / threshold), print as raster. NO HARDWARE? — the built-in Virtual Demo Printer renders every job as an on-screen receipt. One-time purchase. No subscription, no watermarks, no print limits, no ads, no account. Fully offline — the app talks only to printers on YOUR network. Works with Epson, Star, Xprinter, GOOJPRT, Rongta, MUNBYN and generic ESC/POS printers with LAN/WiFi. Bluetooth-only printers: use the Android version's roadmap page — network printing is supported today. Support: https://lampstandtech.com/printdoctor/support
