Local PrintHub

About this app

Local PrintHub transforms your ordinary printer into a simple Wi-Fi printing device. Simply connect your printer to your Android device, and it will instantly function as a wireless print server on your local network.

This allows other devices on the same network—including computers (Windows, Mac, Linux), smartphones, tablets, and POS systems—to print documents and images instantly via the local network, without needing to purchase an expensive new Wi-Fi printer. And no need to rely on external cloud systems.

■ Key Features and Functions

• Upgrade a regular printer: Connect the printer via USB OTG or network (Wi-Fi / LAN) and share it as a local printer.
• Local Print Server: Built-in HTTP Web Server for receiving print commands over Wi-Fi / LAN network.
• Automatic printer discovery: Scan for printers on the LAN using mDNS / Bonjour or manually enter the IP address if the router blocks the search.
• File Support: Print PDF and image files (PNG, JPG) directly.
• Detailed print job settings: Number of copies (1-99), paper size (A4 / Letter or any size supported by the printer), paper orientation, color / black and white, print quality, scaling to fit, and select specific pages.
• Print preview: See the actual print job before printing. • Reduce printing errors and save paper.
• Easy connection: Displays IP address, port, and QR code on the screen, allowing for instant scanning or setup to connect with other devices.
• Print queue management system: Monitor real-time status such as waiting to print, printing in progress, completed, or error reports, with confirmation from the actual printer via IPP standards.
• Seamless background operation: Supports Foreground Service, allowing the server to accept print commands at all times, even when the screen is off or other apps are being used.
• Secure and private: 100% offline print processing; all data remains within the LAN; no files are uploaded outside the system.

■ Supported Devices and Printers

The app works with standard IPP/Driverless printers (the same group that supports AirPrint and Mopria), covering most modern inkjet and laser printers. Both USB OTG and Wi-Fi/LAN connection options are supported.

Brands recognized and automatically detected by the app:
• Canon
• Epson
• Brother
• HP
• Xerox
• Lexmark
• Dymo

Receipt/thermal printers (POS Thermal) such as Xprinter, Gprinter, and models using standard chips: Currently supports "test print" (ESC/POS) to confirm connection. Printing PDF files to thermal printers is under development.

**Important Note: Support depends on the printer "model," not the brand. Printers that specify support for AirPrint, Mopria, or Driverless Printing will work best.** We recommend testing it on your machine first.

Not supported in this version: Bluetooth printers, label/barcode printers (ZPL, TSPL, EPL), Raw Port 9100 printing, PostScript, and printers that require login (IPPS).

■ Tip: Avoid Error 0x00000709 on Windows

Windows users who encounter the message "Operation could not be completed (error 0x00000709)" or are unable to share a printer on the network after updating Windows can bypass this problem with Local PrintHub. This is because the system does not use Windows Sharing (SMB) for printer sharing, but instead sends print jobs via HTTP within the LAN.

• Works immediately: Open a browser on your Windows machine, go to the application's IP address, and drag a PDF or image file to print. No additional installation required.
• Coming soon: A "Virtual Printer Client" add-on for Windows will be available for installation, allowing you to print directly from any program (Excel, Word, ERP, accounting software) by pressing Ctrl + P, just like a regular printer.

■ Suitable for:

• Shops, cafes, restaurants, or POS systems that need to share a printer.
• Offices and home offices that want to share their existing printer with all devices on the LAN.
• Software developers who want to send print commands from a web app or internal program to a printer.

Save costs and increase the convenience of wireless printing with Local PrintHub.
