3. Thermal Image Printer — Best for Photo and Label Printing
Price: Free | Platform: Android only
Thermal Image Printer specialises in printing images, logos, and custom labels from your Android camera roll. It uses advanced dithering algorithms (Floyd-Steinberg, Jarvis Judice Ninke, Sierra) for the sharpest possible thermal image quality.
It also has a full label designer: drag-and-drop text, barcodes, QR codes, serial numbers, dates, and images onto a canvas, then print up to 500 labels at once with auto-incrementing serial numbers.
Best for: Product labels, price tags, shipping labels, photo printing on thermal paper.

4. RawBT (Plugin)
Price: Free / Paid | Platform: Android only
RawBT is a print service plugin — not a standalone app. It must be installed alongside another app that supports it. Useful for developers building their own apps, but not practical for regular users who just want to print receipts. Wi-Fi printing and advanced features require a paid upgrade. No iOS support.
5. Thermer
Price: Free | Platform: Android only
Thermer is a simple thermal printer app with a clean interface. However, it lacks image printing, advanced template customisation, AI generation, and iOS support. Good for basic receipt printing but outpaced by Simple Bluetooth Printer in nearly every feature category.
