Raspberry Pi Setup

See wiki for OS installation on your Raspi with Raspian.

Start your Raspi, login via desktop or remote via SSH with default user Pi with password

 raspberry

Initial configuration:

• Change the default password after first login and note it somewhere!
• Set Timezone
• Setup internet connection (via WLAN oder Ethernet)
• Run raspi-config > 7 Advanced Options to enable SSHD
• Install Updates

Install CUPS

    $ sudo apt-get install libcups2
    $ sudo apt-get install libcups2-dev libcupsimage2-dev git build-essential cups system-config-printer
    // start CUPS
    $ sudo /etc/init.d/cups start

You can reach the CUPS Webinterface via http://localhost:361

To allow your pi user to add printers:

    $ sudo usermod -aG lpadmin pi
    $ sudo service cups restart

Install SQLite3

    sudo apt-get install sqlite3 ruby-sqlite3 libsqlite3-dev

[Optional] Install ZJ-58 CUPS filter

If you use a ZJ-58 thermal printer via USB, you need to install the CUPS filter via github.com/klirichek/zj-58, since the built-in filter does not work! (Of course you can use any other printer, that is installed/accessible with your system)

    $ git clone https://github.com/klirichek/zj-58.git
    $ cd zj-58
    $ make
    $ sudo ./install

Then go to CUPS at https://localhost:631/ + select “Adding Printers and Classes”, then “Printers: Add Printer” and add printer connected via “usb://Unknown/Printer”.

To allow the Raspeberry default user “pi” to access the CUPS admin features:

    $ sudo usermod -aG lpadmin pi
    $ sudo service cups restart

See scruss.com/blog/2015/07/12/thermal-printer-driver-for-cups-linux-and-raspberry-pi-zj-58 for a detailed description.

Assemble the hardware

Put together the pushputton on a breadboard to trigger the printer

Install PRNSTN script

PRNSTN is the script that turns this setup into an internet printing station.

See github.com/ut/PRNSTN for a description of the installation and usage.
