remarkable_printer

Print natively to your reMarkable wirelessly with no extensions or reMarkable cloud.

Install

With the reMarkable connected via USB, execute

make download_prebuilt
make install

This will install and start the printer service on the reMarkable.

Alternatively, you can build the executable yourself by omitting the make download_prebuilt step.

Adding the reMarkable as a printer

Linux (easy)

Set 10.11.99.1 to your device's address or hostname.

make install_config host=10.11.99.1

Linux (manual)

We will add the reMarkable as an Appsocket/JetDirect printer.

Linux

$ sudo system-config-printer
# Add > Network Printer > AppSocket/HP JetDirect
# Enter the address/hostname of the device (10.11.99.1 for USB connected device)
# Forward > Generic > Forward > PDF > Forward
# Set the printer name and save

OSX (manual)

See Add a network printer by its IP address. Choose HP Jetdirect for the protocol.

Caveats

No authentication, so keep WiFi off while not in use.

How it works

Virtually all network printers accept raw Postscript/PDF data on TCP port 9100 via the Appsocket/HP Jetdirect protocol. Sometimes this data is preceded by a few plaintext lines telling the printer information such as the print job name and print settings.

This script simply listens on TCP 9100 and waits for a PDF header, then begins saving data to a pdf file (while also creating the accompanying .metadata file). The output filename is extracted from the print job name line, if it exists.

Testing on host

$ make printer.x86
$ ./printer.x86 -h
Usage of ./printer.x86:
  -debug
        enable debug output
  -host string
        override bind address (default "0.0.0.0")
  -port string
        override bind port (default "9100")
  -restart
        restart xochitl after saving PDF
  -test
        use /tmp as output dir
