NEW GUIDE: BLE Thermal Printer with Epler] writes: When I saw the “cat” printer in this Hackaday article ( ), I simply had to have one for myself. But to be fair, I doubt the CLUE board with its Nordic nRF52840 Bluetooth LE processor, 1 MB of Flash, 256KB RAM, 64 MHz Cortex M4 processor running full-up CircuitPython would have space to pre-process anything but rather simple images on-board.ġ.

Unfortunately the CircuitPython code just prints an image that has been pre-processed by a photo editing application such as the free-open-source cross-platform GIMP photo editor.

#Printer app for mac drivers

For Windows there are drivers available online, search for “Windows thermal label printer driver” without the ” “s.

Where complex drivers come into play is when you want to process an image (scale/dither/B&W-convert) and send it to the label printer. Or add $10-$15 USD to the generic thermal label/receipt printer’s price and it will come with USB/WiFi/BLE straight out of the box. For both WiFi and BLE wireless connectivity simply connect the likes of an Espressif ESP32 module to the UART TTL interface. The RS-232 UART TTL level interface is easily converted to USB using a UART/USB bridge chip (e.g. These generic printers have a RS-232 UART TTL-level interface that supports ESC/POS. The name ESC/P or ESC/POS is also appropriate because the printer commands are preceded by an ESCape character (ASCII code 27).īare-bones generic thermal label/receipt printers can be had cheaply at the likes of AliExpress. More precisely, label/receipt thermal printers use the ESC/POS (Epson Standard Code/Point Of Sale) variant of ESC/P. Posted in Arduino Hacks, Peripherals Hacks Tagged arduino, ble, macOS, mini printer, thermal printer, wireless Post navigationįor scalable text, simple lines, and barcodes, no complex drivers are needed because almost all generic label/receipt printers support the relatively simple Epson Standard Code for Printers, also known as ESC/P. Of course, if that’s all starting to look a little too easy, one can always put the thermal back in thermal printing by using plasma, instead. Small thermal printers make for neat projects, like this retrofitted Polaroid camera, and now that these little printers are both wireless and economical, things can only get easier with the help of a library like this. Print2BLE is a MacOS application that allows dragging image files into the application’s window, and if the preview looks good, the print button makes it come out of the printer as a 1-bpp dithered image.

While experimenting with microcontrollers and BLE thermal printers, he also wanted to explore talking to these printers from his Mac using BLE directly. You can read all about what the library can do in this succinct list of concise functions.īut hasn’t stopped there. Fancier output can be done using Adafruit_GFX library-style fonts and options, which sends the formatted text as graphics. It’s not limited to simple default text, either. That’s a great mix that makes them attractive for projects that would benefit from printing out a hardcopy. These printers are small, inexpensive, and wireless. ’s Arduino library to print text and graphics on BLE (Bluetooth Low Energy) thermal printers has some excellent features, and makes sending wireless print jobs to a number of common models about as easy as can be.
