PrintDoctor: Receipt Printer
Test & fix ESC/POS printers
$14.99 · Designed for iPad. Not verified for macOS.
Receipt printer printing garbage? Drawer not opening? PrintDoctor finds, tests, and fixes ESC/POS printers - right from your phone.
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, no guesswork.
Built for POS technicians, systems integrators, and shop owners who just want the receipt printer to work.
FIND YOUR PRINTER
- Scan your WiFi network and find every printer listening on port 9100 in seconds
- Save printer profiles (name, IP, paper width) for one-tap access
- Works with any ESC/POS printer with a LAN or WiFi interface - Epson, Star, Xprinter, GOOJPRT, Rongta, MUNBYN, and the generic ones
TEST IT
- One-tap test pages: status page, font & style matrix, barcode + QR sample, 58/80mm ruler
- See exactly what your printer can do before you wire it into a POS
FIX GARBLED RECEIPTS (the killer feature)
- Chinese, accents, or symbols printing as garbage? The Codepage Matrix prints the same sample line under every common ESC/POS codepage - including Big5, GB18030, and UTF-8 modes - each one labelled
- Find the row that prints correctly, set that codepage in your POS software, done
CASH DRAWER
- Fire the drawer kick on pin 2 or pin 5 with selectable pulse widths
- Built-in wiring explainer (RJ11/RJ12) for drawer installs
PRINT LOGOS
- Pick any image, preview it in true 1-bit with three dithering algorithms (Floyd-Steinberg, Bayer, threshold), and print it as a raster logo
TRY EVERYTHING WITHOUT A PRINTER
- The built-in Virtual Demo Printer renders every print job as an on-screen receipt - test the whole app before you're even on site
HONEST BY DESIGN
- 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, nothing else
- iPhone can't speak classic-Bluetooth SPP, so PrintDoctor doesn't pretend to - network printing done right, with a clear in-app explanation
