Printing from a RaspberryPi to a line printer (dot matrix, receipt printer) can be done quite simply, by simply writing the text to printer using:

echo "hello printer" > /dev/usb/lp0


  • /dev/usb/lp0 is the location of the printer
  • > is a write to command

Sara wants to expand this mechanism, to have ePub's hyperlinks to make the printer print the words under the hyperlink.

In order to do so, a possible plan:

  • have words in epub under hyperlink pointing towards a server-side script
  • the server side receives the words and writes it to the Pi

How does server writes to the Pi ?[edit]

How to to run commands on server from ebook?[edit]

  • ebook links to cgi script
    • ideally the word wrapped in book would be sent to cgi
    • cgi scripts runs command on server, addressed to Pi
