Description of Each Section (From Japanese Version)

  1. Connected Printer Name
    The name of the printer currently connected will be displayed.
  2. Connect Printer Button
    If a printer is already connected, it will be disconnected.

    Note: If you change the connected printer, the connection might fail. In that case, just close the app and try again.
  3. Print Button
    Print the image displayed in the 10 windows.
    (Since the printer has a narrow width, only the displayed area can be printed.)
  4. Scan QR Code Button
    Scans a QR code containing URL information and automatically opens the corresponding webpage.
  5. Display QR Code URL
    The URL scanned from the QR code will be displayed here.
  6. Sketch Screen Button

    You can print your drawing using the print button in window 3.
  7. Display URL Button
    By pressing this button, the URL entered in window 12 will be shown in window 10.
  8. Display QR Code Button
    The URL entered in window 12 is converted into a QR code and shown in window 11.

    The QR code you created will be displayed.
  12. URL Input Window

Notes for Entering URLs in the Input Window

On recent Android devices, pressing the Enter key alone may not confirm the input.
(This happens when the check mark labeled “A” in the figure above appears.)
Be sure to tap the check mark “A” to confirm your input.
Also, when closing the software keyboard after input, either tap the close icon on the keyboard “B” or tap anywhere outside the keyboard.

Sketch

When you tap the sketch button in window 6, the sketch page appears in window 10.
Draw freely by hand, and then tap the print button in window 3 to print your sketch.

This just opens a drawing website on the web.

Create a webpage with the content you want to print, enter its URL in window 12, generate a QR code, and print it for distribution.
Users can scan the QR code to access the site and print the content themselves.

You can create this kind of system using only this app.

Sketch Source Code

For your reference, the source code of the site mentioned above is provided below.

If you have a web server, you can host this kind of code on it, generate a QR code for the access URL with this app, and distribute it. Users can then scan the QR code to access the site and print the content, allowing you to provide such a system easily.
