# 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](https://support.apple.com/guide/mac-help/add-a-printer-on-mac-mh14004/mac). 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
