A coffee printer uses advanced food-safe inkjet technology to deposit edible ink droplets directly onto milk foam, coffee crema, or beer heads. Operating it is simple: place the cup on the lifting tray, the built-in sensor automatically detects the cup height, adjusts the bed, and prints the image in seconds.

Yes, our edible ink is 100% safe, non-toxic, and FDA-certified. The primary ingredients are water, edible food coloring, and food-grade humectants. It is manufactured under strict food hygiene standards and comes with complete MSDS sheets for safety compliance.

Not at all. The edible ink is completely tasteless, odorless, and colorless once deposited. It will not alter the premium flavor profile, aroma, or texture of your coffee, latte, milk foam, or beer crema.

You can print on any food or drink with a flat, stable surface. For beverages, this includes latte, cappuccino, milk tea, hot chocolate, beer foam, and whipped cream cocktails. For food, it prints beautifully on cookies, macarons, biscuits, cupcakes, and small cakes.

On high-quality, dense milk foam or beer foam, the print will remain sharp and clear for 10 to 30 minutes. The longevity depends entirely on the stability of the foam itself—finer, tighter microfoam holds the design much longer than loose, bubbly foam.

It ranges from 5 to 30 seconds depending on the model and print size. The standard F410S takes about 10–30 seconds, while our high-speed model F410P can complete a full-cup print in just 5–15 seconds, making it ideal for morning rushes and high-volume catering events.

The upload process is incredibly user-friendly and web-based. Customers simply scan the QR code displayed on the printer's screen using their smartphone, upload their photo or design directly from their browser, crop/rotate it, and click submit. There is no need to download any apps.

Daily maintenance is minimal and takes less than 5 minutes. The printer features built-in automatic cleaning cycles that keep the printhead nozzles clear. A daily nozzle check and quick wipe of the outer casing with a damp cloth are all that is needed to ensure daily hygiene.

One standard edible ink cartridge can print approximately 800 to 1,000 cups of coffee, depending on the average size and ink density of the designs. This translates to an extremely low operational cost of around $0.05 to $0.10 per cup.

No. Models like the F410M and F410S feature an integrated 7-inch Android touchscreen tablet built directly into the front panel. It runs standalone and handles all image queues, print settings, and calibrations natively, requiring no external PC or monitor.

Yes, our coffee printers are highly popular for mobile event catering, pop-up shops, exhibitions, weddings, and brand activations. The F410M (Mini) features a compact, lightweight steel frame and built-in screen, making it extremely easy to transport and set up.
