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 GitHub - pierre-muth/polapi-zero: Instant-Printing-Point-and-Shoot camera based on Raspberry pi 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!

i'm don't know what is ur real problem and what type of printer that u use but maby this will help u:
