Setup Guide

1

🖨ī¸ Get a Thermal Printer

PrinterBot works with ESC/POS compatible thermal printers connected via USB.

✅ Recommended Printers

  • Epson TM-T88 Series (TM-T88IV, TM-T88V, TM-T88VI) — Best compatibility
  • Epson TM-T20 Series — Great budget option
  • Generic 80mm Thermal Printers — Most work, but may need configuration

💡 Pro Tip

You can find used receipt printers on eBay for $20-50. Look for "thermal receipt printer USB" — most will work!

🔧 Install USB Drivers (Zadig)

PrintsAlot communicates directly with your printer via USB. We need to install a special driver using Zadig.

  1. Download Zadig from zadig.akeo.ie
  2. Connect your printer via USB and turn it on
  3. Run Zadig as Administrator
  4. Go to Options → List All Devices
  5. Select your printer from the dropdown (look for "EPSON" or your printer name)
  6. Set the driver to libusbK
  7. Click Replace Driver (or Install Driver)

⚠ī¸ Important

After installing the Zadig driver, your printer will no longer work with regular Windows printing apps. To revert, use Device Manager to uninstall the driver.

🔧 Troubleshooting

Printer not detected?

  • Make sure Zadig driver is installed correctly
  • Try a different USB port
  • Check if the printer is powered on
  • Restart the PrintsAlot app

Prints are blank or garbled?

  • Check printer width setting (default 384px, max 800px)
  • We have found 522px works best for 80mm printers
  • Make sure you're using thermal paper (not regular paper)
  • Try a test print from the web UI

Link command not working?

  • Make sure you're DMing the bot, not posting in a channel
  • Check that the pairing code hasn't expired (15 min)
  • Refresh the web UI to get a new code

App won't start?

  • Check printsalot.log next to the exe for errors
  • Make sure port 8456 isn't in use by another app
  • Try running as Administrator
