RaspberryPi ​

Hypriot Docker ​

Flash SD card using flash tool.

bash
# Install prerequisites
brew install pv
brew install awscli

# Download binary
curl -LO https://github.com/hypriot/flash/releases/download/latest/flash
chmod +x flash
sudo mv flash /usr/local/bin/flash

# Flash the sd card passing the static.yml cloud-init 
flash -u static.yml ~/Downloads/hypriotos-rpi-v1.9.0.img.zip

# Alternatively download & flash
flash https://github.com/hypriot/image-builder-rpi/releases/download/v1.9.0/hypriotos-rpi-v1.9.0.img.zip

Pi-hole ​

Disable resolved before running pi-hole

bash
sudo systemctl disable systemd-resolved.service
sudo service systemd-resolved stop

Cups Server ​

Based on: Docker-Cups-Server rpi3 = Raspberry Pi3. Running docker image of cups server Build your own image using dockerfile based on ARM architecture.

bash
# Build cupsd
docker build -t cupsd .

# Get printer's info
BUS=$(lsusb | grep Brother | awk '{print $2}')
DEV=$(lsusb | grep Brother | awk '{print $4}')
PRINTER="/dev/bus/usb/$BUS/$DEV"
# OR
``/dev/bus/usb/001/004``

# Run cupsd docker image passing $PRINTER device
docker run -d -p 631:631 --name cups-server --net=host --device=$PRINTER cupsd

Server setup:

  • Attach your printer to the rpi3.
  • Exec into the container running cups-server.
  • Find out the URI of your printer with lpinfo -v |grep usb

In my case the output is

direct usb://Brother/HL-L2300D%20series?serial=E73860G5N986807

so the URI is

usb://Brother/HL-L2300D%20series?serial=E73860G5N986807

Now that we know the URI, we can add the printer to the system. In my case the command is:

lpadmin -p HL-L2300D -v usb://Brother/HL-L2300D%20series?serial=E73860G5N986807

Now the printer is known to the system but disabled. You can check the status with: lpstat -p $NAME -l In my case I got:

$ sudo lpstat -p HL-L2300D -l
printer HL-L2300D disabled since Sun 02 Sep 2018 16:22:43 UTC -
	reason unknown

We now have to enable the printer with sudo cupsenable $NAME, which in my case translates to

cupsenable HL-L2300D

It is now enabled:

$ sudo lpstat -p HL-L2300D -l
printer HL-L2300D is idle.  enabled since Sun 02 Sep 2018 16:23:17 UTC

Finally we have to tell CUPS that it may accept print tasks for this printer with:

cupsaccept HL-L2300D

Hint: If something goes wrong, you can remove the printer with lpadmin -x $NAME and start from scratch.

Client setup:

Install the appropriate driver for your printer under MacOS or Windows. On MacOS:

  • Bring up the System Preferences tool.
  • Choose Print and Scan.
  • Click on the plus sign to add a printer.
  • Choose IP (as opposed to Default, Fax or Windows)
  • Put an address of 192.168.1.10:631
  • Use IPP protocol
  • Put a queue of /printers/<CUPS-Queue-Name>
  • OPTIONALY, change name and location
  • Use Brother 2300D driver from the driver dropdwon (not Generic PostScript)
  • Click on Add
