Receipt Markup Language – A simple tool for printing to thermal printers

Pt 803

Receipt Markup Language. Ames writes –

I am using the 2.25″ thermal receipt printer for an art project. I wanted an easy way to print things directly from my computer, so I wrote a little script to do that. The program reads input (from a document, or from the command-line) and sends it to the printer. Commands are parsed for images, barcodes, and other special printer functions.

Adafruit IoT Printer Project Pack “Internet of Things” printer. Build an “Internet of Things” connected mini printer that will do your bidding! This is a fun weekend project that comes with a beautiful laser cut case. Once assembled, the little printer connects to Ethernet to get Internet data for printing onto 2 1/4″ wide receipt paper. The example sketch we’ve written will connect to Twitter’s search API and retrieve and print tweets according to your requests: you can have it print out tweets from a person, a hashtag, mentioning a word, etc! Once you’ve gotten that working, you can of course easily adapt our sketch to customize the printer.

The project is not very difficult but does require some light soldering, so you’ll want to have a little experience with a soldering iron. You’ll also need a small flathead screwdriver to assemble the box. It’s also best if you’ve had a little Arduino experience so you can feel comfortable downloading the IDE and uploading our example sketch.

Contains:

Kit-Parts

This pack does not contain an Arduino+Arduino Ethernet Shield, Arduino Ethernet or Ethernet cable To complete the project you will need to add either an Arduino + Ethernet Shield or an Arduino UNO Ethernet. If you’re using an Arduino UNO Ethernet you will also need an FTDI friend or FTDI cable to upload the sketch. A plain straight-thru Ethernet cable is also required (any length)

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
