Add support for so-called "driverless" printing that autofetches CUPS drivers, without the need for us to package up a billion PPD files, like
the ones we can't distribute.
Also investigate if this bails us out of the sorry mess of Brother drivers
Edit: Also add https://github.com/google/cloud-print-connector because popey said so. (USB printer attached to Solus box and print from a phone. yay)

I think driverless printing should already work and it shouldn't be hard to setup since D530 was already rolled out.
Here are the basic instructions to configure it:
Make sure the printer is turned on and connected to the computer ?
Make sure to enable cups-browsed if not already done:
sudo systemctl enable cups-browsed.service
Edit the file /ect/cups/cups-browsed.conf and uncomment one of these lines:
CreateIPPPrinterQueues driverless
CreateIPPPrinterQueues All
Start or restart the service:
sudo systemctl restart cups-browsed
Check the existence of the queue with:
lpstat -t (the device-uri should begin ipp:// or most likely usb:// for usb printers)
Check the queue options with:
lpoptions -p <queue_name> -l
Could anyone try this please ?
Make sure to enable cups-browsed if not already done:
sudo systemctl enable cups-browsed.serviceEdit the file /ect/cups/cups-browsed.conf and uncomment one of these lines:

I just tried this and I cannot restart the cups-browsed service. However it did create the symlink to enable the service so I have no idea what is wrong with it.
Failed to restart cups-browsed.service: Unit cups.service failed to load: No such file or directory.
Also I do this all the time too but I think you meant /etc/cups/cups-browsed.conf :)
@kyrios123 I received the same as above, using cups 2.2.3 on Solus Shannon, fully updated
Then you missed the update. I tried to make it visible. ?
The update of cups might be released very shortly. It's being tested atm.
@kyrios123 @ikey @alecbcs I just got this working on a fully updated, fresh install utilizing Shannon. Done in a VM to ensure no contamination from anything else.
Required package: nss-mdns - This is the only additional package I had to install after a clean install of Solus and fully updating via Shannon repository.
sudo systemctl enable avahi-daemon.service
sudo systemctl start avahi-daemon.service
Our default /etc/nsswitch.conf is effectively empty. I borrowed one from an Arch install, and did the following: change the hosts line to include mdns_minimal [NOTFOUND=return] before resolve and dns
Following this, open print settings, unlock it, and add a printer. It almost immediately found my printer by IP address. Give it a minute, and it'll find it by IPP. In my case, the address is Canon59fc21.local. As displayed from Arch system-config-printer GUI this is ipp://Canon59fc21.local:631/ipp/print - Unsure why I am unable to view this full address from print settings in Solus.
Tested with a Canon MF229DW connected to my LAN via WiFi. Below is the /etc/nsswitch.conf I am using.
Packages/versions used:
In short, this appears to be a dependency, config, and service issue. Not a cups version issue.
#Begin /etc/nsswitch.conf passwd: compat mymachines systemd group: compat mymachines systemd shadow: compat publickey: files hosts: files mymachines mdns_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns myhostname networks: files protocols: files services: files ethers: files rpc: files netgroup: files # End /etc/nsswitch.conf
@broken6r actually the only line you need in /etc/nsswitch.conf for this to work is the the hosts: one and the below line is probably better unless you have to lookup both ipv4 and ipv6 for .local hosts on your network.
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
@ikey is there a way to update /etc/nsswitch.conf when nss-mdns is installed without having to use comar ?
The idea would be to comment the host line and replace it with the above one when the package is installed to have something working out of the box.
Pre-enabling avahi service is perhaps a good idea as desktops are almost always connected to a network nowadays.
What do you think ?
We want a stateless nsswitch.conf ideally tbqh. Also we want to specify mdns_minimal to be non fatal.
^ Not going stateless just yet, need to unfuck the stateless glibc patches into a fresh set..
