CUPS Printer Server on the Raspberry Pi

Recently acquired a $30 laser printer from a flash sale. The B/W Brother HL-L2320D. Decided to use CUPS on the RPi to share the printer on the local network. First things first, Brother doesn’t provide drivers for the printer compiled for the ARM architecture. But the brlaser project mercifully has support for many series.

After setting up the Pi, the first thing to do was find if there was a debian package for this library

[email protected]:~ $ apt-cache search brlaser
printer-driver-brlaser - printer driver for (some) Brother laser printers

That’s great! But hold on a second, what’s this?

[email protected]:~ $ apt-cache policy printer-driver-brlaser
printer-driver-brlaser:
  Installed: (none)
  Candidate: 4-1
  Version table:
     4-1 500
        500 http://raspbian.raspberrypi.org/raspbian buster/main armhf Packages

Oh great, it’s V4. Now that’s not necessarily bad, but it’s better to get v6 from the repo directly.

Setup the toolchain and dependencies

sudo apt install libcupsimage2-dev libcups2-dev cmake cups

Clone the repo and install the lib

git clone https://github.com/pdewacht/brlaser.git
cd brlaser
cmake .
make
sudo make install

Great! now let’s configure to access cups remotely. I don’t like attaching my peripherals to the Pi and hauling my monitor to it.

Allow access to CUPS admin

sudo cupsctl --remote-admin --remote-any --share-printers

This will modify /etc/cups/cupsd.conf to open up everything. Now the admin interface is available to be accessed remotely via the address https://<pi-address>:631/admin

Add the printer

I added the printer by going to /admin and Add printer. It’s pretty straightforward, just needed to make sure the printer is shared and HL-L2300 series is a viable driver. The default options are enough and make sure you select the printer as server default.

MacOS & Windows

Pretty straightforward access. Just go to printers and the printer shows up. If it doesn’t show up for Mac OS, install and enable avahi-daemon

sudo apt install avahi-daemon

Start/Restart & Enable it

sudo systemctl restart avahi-daemon
sudo systemctl enable avahi-daemon

If Windows can’t find it, maybe install the Samba package

sudo apt install samba
sudo systemctl restart smbd

Go to the printers section under /etc/samba/smb.conf and update it to reflect the following

[printers]
   comment = All Printers
   browseable = no
   path = /var/spool/samba
   printable = yes
   guest ok = yes
   read only = yes
   create mask = 0700

# Windows clients look for this share name as a source of downloadable
# printer drivers
[print$]
   comment = Printer Drivers
   path = /var/lib/samba/printers
   browseable = yes
   read only = no
   guest ok = no

Now I just need to the figure out the bug up Linux’s ass and get the trifecta working. But it works great on Mac OS and Windows 10
