Printer Setup & Configuration

Karafuru prints photo grids directly after each session. Setting up your printer takes just a few minutes.

Supported Printers​

Karafuru works with any USB-connected printer that your Windows PC recognizes:

  • Dye-sublimation printers (DNP, Mitsubishi, HiTi)
  • Inkjet printers (Canon, Epson, HP)
  • Thermal printers
  • Any printer Windows can detect

USB is required. Network or Bluetooth printers are not currently supported.

Steps to Connect​

1. Plug in your printer​

Connect your printer to your PC via USB cable. Power it on.

2. Install the driver​

Windows usually auto-installs the printer driver. If it doesn't:

  1. Go to your printer manufacturer's website
  2. Download the Windows 10/11 64-bit driver
  3. Install it
  4. Restart your PC

3. Test the printer in Windows​

  1. Go to Settings → Devices → Printers & Scanners
  2. Your printer should appear in the list
  3. Click your printer and select Print test page

If the test page prints successfully, your driver is installed correctly.

4. Open Karafuru​

When you launch Karafuru, it scans for connected printers. Your printer should appear automatically.

Go to Settings → Printer Configuration to confirm.

Configure Paper Size​

Before running an event, choose your paper size and calibrate.

Steps​

  1. From the dashboard, click Settings → Printer Configuration
  2. Select your paper size:
    • 2R (2" × 6") — Tall, narrow format for 4 photos in a vertical strip
    • 4R (4" × 6") — Standard postcard size
    • A4 / Letter — Full page (fits multiple grids)
  3. Click Test Print to print a sample
  4. Check that photos are centered and properly positioned on the paper
  5. If calibration is needed, adjust the offsets using the on-screen controls
  6. Print another test page and confirm alignment
tip

Spend 5 minutes calibrating before your first event. Proper calibration prevents wasted paper and ensures professional-looking prints.

During Events​

Once configured, printing is fully automatic:

  1. Guest takes 4 photos
  2. Photos arrange in your selected grid layout
  3. Payment screen appears (optional QRIS)
  4. Grid automatically prints without you touching anything

Your printer runs continuously during busy sessions. Make sure you have enough paper and ink.

Troubleshooting​

Printer is not detected

  • Unplug the USB cable and plug it back in
  • Restart Karafuru
  • If still missing, go to Settings → Printer Configuration and manually select your printer from the list

Photos print off-center

  • Click Test Print again
  • Use the calibration adjustment sliders to center the image
  • Save and print another test page

Printer goes offline during a session

  • Check the USB cable connection
  • Make sure the printer has paper and ink
  • Restart Karafuru
  • Queued photos will print once the printer comes back online

I'm running low on paper/ink

  • Karafuru continues operating — photos are saved locally and can be printed later
  • Refill your printer and it will resume printing automatically
