Printers

To get your printer working you will mainly need to install and setup cups.

If you choose the printer support option on the installer you will already have a working cups setup and only need to add your printer.

To start with cups and an usb connected printer:

sudo pacman -Syu cups cups-filters cups-pdf system-config-printer --needed

To get full cups with support for many different printers per default. Install this packages on top of that:

sudo pacman -Syu ghostscript gsfonts foomatic-db-engine foomatic-db foomatic-db-ppds foomatic-db-nonfree foomatic-db-nonfree-ppds gutenprint foomatic-db-gutenprint-ppds --needed

For QT environments (like KDE/plasma LXQT):

sudo pacman -Syu print-manager --needed

enable socket, which will listen if print-job is calling and then enable the service:

sudo systemctl enable --now cups.socket

or using the service, which will be running constantly.

sudo systemctl enable --now cups.service

For network printer support, check if avahi is installed and its daemon is running:

systemctl status avahi-daemon

if you get an error or it shows disabled not running:

sudo pacman -Syu avahi --needed
sudo systemctl start avahi-daemon
sudo systemctl enable avahi-daemon

Automatically add network printers:

CUPS can use Avahi browsing to discover unknown shared printers in your network. This can be useful in large setups where the server is unknown. To use this feature, set up local hostname resolution, and start both avahi-daemon.service and cups-browsed.service. Jobs are sent directly to the printer without any processing so the created queues may not work, however driverless printers such as those supporting IPP Everywhere or AirPrint should work out of the box.

This is mainly usefull for mobile devices or for usage in offices where a number of changing network printers is used.

But you can use this at home too, it can be less troublesome in case, as you do not need to setup drivers and uri.

sudo systemctl enable --now cups-browsed.service

And make sure mdns (local host name resolution) is enabled and added to access firewalld. see here: https://discovery.endeavouros.com/wp-admin/post.php?post=1029&action=edit#network-printer

With this you will get network printers automatically added, without any need to setup.

Troubleshooting:

Network printer not reachable

It is a common issue that you can not get wifi printers to print, especially some Brother wifi printers.

It can be required to enable local hostname resolution for avahi to be able to connect to your network printer:

https://wiki.archlinux.org/title/Avahi#Hostname_resolution

Avahi provides local hostname resolution using a “hostname.local” naming scheme. To enable it, make sure the nss-mdns package is installed and avahi-daemon.service is running:

pacman -Qs nss-mdns to see if it is installed local:

➜ ~ » pacman -Qs nss-mdns local/nss-mdns 0.14.1-3 glibc plugin providing host name resolution via mDNS

Make sure avahi-daemon is running:

systemctl status avahi-daemon.service

Then, edit the file /etc/nsswitch.conf and change the hosts line to include mdns_minimal [NOTFOUND=return] before resolve and dns:

Restart avahi-daemon and NetworkManager after this, or reboot machine:

sudo systemctl restart avahi-daemon NetworkManager

Firewall is blocking mdns:

To make use of local hostname resolution (mdns) you need to change firewalld from public to home (zone change).

Assigning a Zone to a device will also be remembered on network changes, so if you leave home network and per example connect to a Wi-Fi network outside it will always use the default set public zone as long as you do not change that manually.

To make these permanent you need to set Configuration to Permanent and run the change to home zone, if Runtime is used it will get reset after logout. Now you should see network printers in printer setup tools showing up.

Procedure to find the right driver for your printer:

Go to the open printing website and search for whether your printer is supported on Linux at all, and what driver options are available.

This is what the result will look like:

On top you will see whether or not there is a working driver for your printer
second it will show available driver options, in the example, you see Type: Ghostscript built-in, so go to package search on Archlinux (or use the tool of your choice) you will find GhostScript (already installed if you followed the tutorial from top to bottom)

So install the driver available for your device, and proceed to install and configure the printer. But take a look at these links first, as it could be that your printer needs some extra configuration done to work properly:

Some links to common printers’ information on Archwiki:

Canon printers
Epson printers
HP printers
Lexmark printers
Oki printers
Samsung printers
Brother printers

Notes on Common ways to install printer drivers:

Mostly all printers will be using cups as a backend to communicate with your system, but different brands will be needing different ways to get printers fully functional:

Hewlett and Packard (HP) printers:

Some of the HP-printers needs a proprietary plugin to work, this can be installed by hplip.

Here is an overview of some common printers and working drivers on Archwiki:

Printer-specific_problems#HP

Most drivers for hp-printers come with the HPLIP package you can install this with:

sudo pacman -S hplip

install python-pyqt5 to run GUI and hp-toolbox:

sudo pacman -S python-pyqt5

now run the program to install new printer queue and the possibly needed proprietary plugin for some hp-printers:

sudo hp-setup -i for CLI install without a GUI

or run hp-setup from menu.

The tool guides you through the installation – simply read the instructions.

Current notes (29.5.2020):

There is currently an issue with getting keys from keyservers, this also seem to effect the hp-plugin. Verify downloaded plugin to see what caused a failed to install. To solve this you need to change the server used by the tool:

sudo nano /usr/share/hplip/base/validation.py
change the server to keyserver.ubuntu.com like this:

def init(self, pgp_site = 'keyserver.ubuntu.com', key = 0x4ABA2F66DBD5A95894910E0673D770CDA59047B9):

Save the file by pressing [Ctrl+X].

Then run sudo hp-setup -i again.

You have your printer added now, so you do not need to set it up again as what follows, but you can use system-config-printer to setup configuration for papersize e.t.c.
