Lionel Maes : Printing Beaufort : Protocol

The HP C6602B is a blue inkjet cartridge with an integrated printhead, compatible with HP ADDMASTER IJ6000 POS (Point of Sale) printer models, and therefore intended for use in a "transactional printing system"—such as for tickets, receipts, and invoices.

The HP C6602B is designed to perform mechanical back-and-forth movements controlled by software-driven motors, inside a black or white plastic housing, at a distance of less than 1 mm from the print media, which must not exceed 7.5 cm in width.

And

Connect the HP C6602B to an InkShield electronic circuit—developed and published in 2011 by Nicholas C. Lewis—connected to an Arduino Uno microcontroller.

Then

Keep it stationary, with the print heads facing upward, and launch a print job, that is, the ejection of ink droplets for each dot that makes up each letter of each word, for each level of the Beaufort scale—which has 12 levels—every 3 minutes.

Hold it a few centimeters away from the paper and print continuously for a length of 15 meters, without line breaks.
