Billfinch: Thermal Printer App

Billfinch is a thermal printer app for small shops. Print clean receipts with your logo, QR and barcode on a 58 mm or 80 mm Bluetooth receipt printer. Printing is free with no limit and no watermark. It also works as a POS thermal printer driver, so Chrome, PDF files and your POS app print through it. CLEAN RECEIPTS ON CHEAP PRINTERS Billfinch draws the whole receipt as one black and white picture, then sends it to the printer. The paper preview is exactly what comes out: no random symbols, no wasted paper. PRINT FROM OTHER APPS AND A WEB POS Billfinch works as the ESC/POS print service and POS printer driver for your thermal printer: • Print menu: in Chrome, a PDF, Gallery or another POS app, choose "Billfinch thermal printer". The page prints on 58 or 80 mm roll paper with no margins. Turn it on once in Android Settings › Printing • Share or Open with: send a PDF, picture or text to Billfinch and tap Print once • Web POS: your page opens a billfinch://print link (or intent:// in Chrome) and the receipt prints at once, with no dialog, after you allow it one time. It takes text, simple HTML, a picture (base64 or URL) or raw ESC/POS. Developer guide: https://tinyfair.my.id/billfinch/developers/ SET UP IN 3 STEPS Pick your printer and Billfinch prints one test sheet by itself: a paper width ruler and 3 blocks in different picture modes. If it looks right, tap "It printed fine". If not, tap the number that printed cleanly and choose 58 or 80 mm. CONNECT YOUR PRINTER • Bluetooth: pick a printer already paired with your phone, whatever its name • Wi-Fi printer by IP address, port 9100 • USB cable with an OTG adapter • Advanced: 48 or 80+ mm paper, and a slower sending speed for slow printers YOUR RECEIPT TEMPLATE • Shop name, address, phone and footer • Logo from your shop initials, or your own picture • Your own QR, such as a static QRIS code or a link. Billfinch only prints it; it does not process payments • Code 128 barcode and automatic receipt numbers with your prefix • Tax included in prices or added on top A BILL PRINTER FOR THE COUNTER To print receipt slips fast, just type: item name, Enter, price, Enter, and the next line appears. Items you sold before are suggested with their price, everything saves by itself, and the Print button stays at the bottom: two taps from the home screen to paper. Set the quantity, add a discount, then take cash and see the change, or mark the sale paid by QR or card. Prices use your country's currency. HISTORY AND PICTURES Receipts are grouped by day: search them, print one again, or share it as a PNG image. You can also print a photo or logo in black and white. WHICH PRINTERS WORK? Works with most ESC/POS Bluetooth thermal receipt printers, 58 mm and 80 mm. Label printers (TSPL) and cat printers are not supported yet. Have a 58mm thermal printer at the counter and an 80 mm one in the kitchen? Pro keeps both. FREE AND PRO Printing stays free. Billfinch Pro adds unlimited templates (3 on free), unlimited logo pictures (1 on free), several saved printers (1 on free), CSV export of your history, and no ads. Choose yearly with a 7-day free trial, monthly, or a one-time lifetime purchase on Google Play, or get Pro for 24 hours by watching 2 short videos. ADS STAY AWAY FROM THE CHECKOUT No ads on the receipt screen or while printing, and never on your paper. Free users see a small banner in History and Settings and, now and then, a full-screen ad after leaving the template editor or a picture print. PRIVATE BY DEFAULT No account. Receipts, items and templates stay on your phone and are never sent to us. Bluetooth needs only the "Nearby devices" permission, with no location access. Billfinch is an independent thermal printer app by Tinyfair and is not affiliated with printer makers. Templates are for your own shop only. Available in 12 languages.

Leaving Billfinch with Back may now show a short, skippable note inviting you to rate the app on Google Play. It shows at most 3 times and never again after you rate. Settings also has a new Rate Billfinch row.
