Description
The NETUM GD-85 is a portable, inkless A4 thermal printer that prints documents, PDFs, web pages and photos straight from your phone, tablet or laptop. It uses heat instead of ink or toner, runs on a built-in rechargeable battery, and connects by Bluetooth or USB, so you can print in the car, on a job site, at a client’s office or in a hotel room.
Why Choose an Inkless Portable A4 Printer?
- No ink, no toner, no cartridges – thermal printing uses only thermal paper, so there is nothing to refill or dry out.
- Full A4 page width – print contracts, invoices, delivery notes, homework, recipes and travel documents at full page size.
- Built-in battery – print anywhere without a power outlet.
- Bluetooth + USB – works with Android, iPhone/iPad (iOS) and Windows.
- Sharp 203 dpi output – clear text and readable images.
- Light and compact – fits in a laptop bag or glove box.
Who Is It For?
- Field workers and contractors – print estimates, work orders and receipts on site.
- Delivery drivers and sales reps – print invoices and delivery notes from the vehicle.
- Students and travelers – print notes, tickets and documents without a full-size printer.
- Small offices and home users – a no-maintenance backup printer that never needs ink.
How to Print from Your Phone or Laptop
From iPhone or Android
Charge the printer, turn on Bluetooth, open the companion app and pair the printer. Then open a PDF, photo, web page or document and print it from the app.
From a Windows computer
Connect the printer with the USB cable, install the driver, and print from any program as you would with a normal printer.
Load thermal paper
The GD-85 prints only on A4 thermal paper. Regular copy paper will not work, because the image is created by heat.
