How to Print a Thermal Receipt from Your Browser

Printing a thermal receipt from your browser is straightforward once your printer is set up correctly. This guide walks through the exact steps for Chrome, Firefox, and Safari — and covers what to do if you don't have a thermal printer.

Step 1: Create Your Thermal Receipt

Open the thermal receipt generator, fill in your business name, items, tax, and payment method, and preview the receipt.

Step 2: Connect Your Thermal Printer

Make sure your thermal printer is:

• Connected to your computer (USB, Bluetooth, or network)
• Loaded with 80mm thermal paper roll
• Turned on and showing as ready

Common thermal printers for receipts:

Budget options like the MUNBYN work well for low-volume vendors and market stalls.

Step 3: Open the Print Dialog

Click the Print button in the receipt generator, or press Ctrl+P (Windows) / Cmd+P (Mac) from the preview.

Step 4: Set the Correct Paper Size

This is the most important step. In the print dialog:

Chrome:

1. Click More settings
2. Under Paper size, select your thermal printer's roll size
3. If 80mm is not listed, click Manage custom sizes and add: Width = 80mm, Height = 200mm (or longer for more items)

Firefox:

1. Click Properties next to your printer name
2. Go to Paper/Quality tab
3. Select the 80mm roll paper size

Safari (Mac):

1. Click Show Details
2. Change Paper Size to your thermal printer's roll size
3. If not listed, go to System Preferences → Printers & Scanners → your printer → Options & Supplies to configure

Step 5: Disable Headers and Footers

In Chrome: Under More settings, toggle off Headers and footers

In Firefox: Under Options, uncheck Print headers and footers

In Safari: Uncheck Print headers and footers in the print dialog

This removes the browser's URL and page title from the printed receipt.

Step 6: Print

Click Print — the receipt sends to your thermal printer and prints in seconds.

Printing Without a Thermal Printer

If you don't have a thermal printer:

Option 1 — Download as PDF Download the receipt as PDF and send digitally to the customer by email, WhatsApp, or SMS.

Option 2 — Print on standard paper Print on A4 or Letter paper — the narrow receipt prints centered on the page. Cut to size if needed.

Option 3 — Screenshot Take a screenshot of the receipt preview and share as an image.

Troubleshooting

Receipt prints too wide: The paper size is set to A4 instead of 80mm roll. Change in print settings.

Receipt cuts off at the bottom: The custom paper height is too short. Increase the height value in custom paper size settings.

Printer not found: Check USB or Bluetooth connection and make sure the printer driver is installed.

Output is blank: Thermal paper is loaded upside down — flip the roll and try again. Thermal paper only prints on one side.

Final Takeaway

Printing a thermal receipt from your browser takes under two minutes once your printer is set up. The key step is setting the correct 80mm paper size in your print dialog — everything else is standard. If you don't have a thermal printer, the PDF download works just as well for digital receipts.
