Print grayscale image with Arduino Yun + Thermal Printer

Hi everybody!

i'm trying to print some image i have in my Yun SD with thermal printer, but i don't find any reference online. Everybody use Raspberry Pi in projects like https://github.com/pierre-muth/polapi-zero but i know also that Yun has Linux inside.

Is it possible to convert ad image with Floyd-Steinberg dithering (via command line) and send to Thermal Printer like the example below?

THX u!

|500x333

i'm don't know what is ur real problem and what type of printer that u use but maby this will help u: https://learn.adafruit.com/mini-thermal-receipt-printer/microcontroller
