RonInk: Thermal Printer

Make everyday thermal printing simple with RonInk.

Print text, photos, selected PDF pages, receipts, QR codes, and barcodes from your Android phone using a compatible ESC/POS thermal printer.

CONNECT YOUR PRINTER
• Bluetooth: connect to a printer already paired in Android Settings.
• USB: connect through a supported USB OTG connection.
• Wi-Fi or LAN: enter your printer’s network address and port.

CHOOSE WHAT TO PRINT
• Text and notes: write or paste text with automatic line wrapping.
• Photos: turn images into monochrome prints.
• PDF pages: select a page and fit it to your paper width.
• Receipts: enter your business name, items, quantities, prices, and footer.
• QR codes and Code 128 barcodes: create codes and preview them before printing.

PREVIEW AND ADJUST
• Paper presets for 58 mm / 384 dots and 80 mm / 576 dots.
• Adjustable darkness and optional photo dithering.

PRINT FROM OTHER APPS
Share supported text, images, or PDF files to RonInk. You can also enable the RonInk print service in Android Settings to print from apps that support Android printing.

KEEP RECENT PRINTS HANDY
Your last 20 print jobs are saved locally with previews for reprinting. Clear your print history whenever you choose.

ENGLISH AND INDONESIAN
RonInk follows your phone’s language, with English as the fallback. You can also select English or Bahasa Indonesia in Settings.

PRIVACY AND ADS
No account is required. RonInk does not upload your print documents to a developer-operated server or send their contents to AdMob.

The app contains Google AdMob ads. An optional rewarded ad can unlock 30 minutes without banners or interstitial ads. Watching a rewarded ad is not required to print. Advertising data practices are explained in the privacy policy available inside the app.

PRINTER COMPATIBILITY
RonInk uses ESC/POS GS v 0 raster printing. Compatibility depends on your printer’s supported commands and connection type. Bluetooth printing uses Classic SPP. Printers requiring proprietary protocols may not be supported.

Run a test print before regular use. A successful transfer means data was sent; it does not confirm that paper was printed. Network printing uses raw TCP, so use a trusted local network.
