ThermaCanvas

ThermaCanvas makes Bluetooth thermal printing simple and flexible. Connect a compatible ESC/POS Bluetooth printer, create your content, preview exactly what will be sent, and print directly from your Android device.

QUICK PRINT

Create reusable print layouts using multiple content blocks. Add, edit, reorder and combine:

• Text
• Images
• QR codes
• Barcodes

Save multiple Quick Prints and reopen them whenever you need to edit or print again.

TEXT PRINTING

Customize text with:

• Multiple text sizes
• Bold and underline
• Left, center and right alignment
• Line spacing
• Character spacing

IMAGE PRINTING

Prepare photos, logos and graphics for thermal printing with built-in image tools:

• Crop and rotate
• Resize for paper width
• Brightness adjustment
• Grayscale preview
• Threshold processing
• Floyd-Steinberg dithering

The original image remains unchanged while ThermaCanvas prepares an optimized monochrome version for printing.

DESIGN STUDIO

Create custom print layouts using the visual Canvas Design Studio.

Add:

• Text
• Rich Text
• Images
• Logos
• Lines
• Rectangles
• Dividers
• QR codes
• Barcodes
• Tables
• Prices
• Date
• Time

Move and resize elements directly on the canvas. Align elements, change their layer order, lock them, duplicate them, and use undo or redo while designing.

Save multiple designs and return to edit them later.

QR CODE PRINTING

Create QR codes for:

• Text
• URLs
• Phone numbers
• Email addresses
• Wi-Fi information

Choose the QR error-correction level and include the code in a Quick Print or custom design.

BARCODE PRINTING

Create and print commonly used barcode formats:

• Code 128
• Code 39
• EAN-13
• EAN-8
• UPC-A
• ITF

ThermaCanvas validates supported barcode content before printing.

ACCURATE PRINT PREVIEW

Preview your document before sending it to the printer.

The preview is generated from the same monochrome raster output used for printing, helping you see how your content will be prepared for the thermal printer.

Zoom the preview, choose the number of copies and check the final layout before printing.

58MM AND 80MM PRINTERS

ThermaCanvas includes printer profiles for common:

• 58mm thermal printers
• 80mm thermal printers

Configure paper width, character encoding, paper feed and cutter behavior according to your printer.

PRINT HISTORY

Keep a local history of sent and failed print jobs.

You can:

• View previous jobs
• Preview them again
• Reprint them
• Delete unwanted history

Print-job snapshots are preserved so previously printed content does not change when the original design is edited later.

BLUETOOTH PRINTER CONNECTION

Connect compatible Bluetooth ESC/POS printers using standard Bluetooth SPP/RFCOMM communication.

ThermaCanvas includes:

• Bluetooth printer pairing
• Paired-printer selection
• Connect and disconnect controls
• Foreground auto-reconnect
• Connection and write timeouts
• Test printing
• Printer diagnostics
• Connection recovery tools

PRIVATE AND OFFLINE

ThermaCanvas is designed to work locally on your device.

• No account required
• No cloud sync
• No analytics
• No ads
• No Internet connection required for printing

Your saved prints, designs, images and print history remain on your device.

COMPATIBILITY

ThermaCanvas is designed for compatible Bluetooth thermal printers that support standard ESC/POS printing over Bluetooth SPP/RFCOMM.

Printer capabilities can vary by manufacturer and model. Features such as paper cutting depend on the capabilities of the connected printer.

Create it. Preview it. Print it with ThermaCanvas.
