Tutorial : how add a wireless printer and make it works ?

hello after i resolve my problem with adding  a printer and make it useful (make it works  )on manjaro and arch (by reading tutorials and wikis) i decide to share my experience so :

1- Install the avahi package

pacman -S avahi

2- Install the nss-mdns package for hostname resolution

pacman -S nss-mdns

3- Start and enable avahi-daemon.service 

systemctl start avahi-daemon.service

systemctl enable avahi-daemon.service

4- Then, edit the file /etc/nsswitch.conf and change the line:

hosts: files dns myhostname

to:

hosts: files mdns_minimal [NOTFOUND=return] dns myhostname

5- Install the cups, ghostscript, and gsfonts packages.

pacman -S cups ghostscript gsfonts 

6- Start and enable org.cups.cupsd.service

systemctl start org.cups.cupsd.service

systemctl enable org.cups.cupsd.service

( Optionally; 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, start cups-browsed.service)

7- Optionally ; some linuxers  claim that they have problem when try adding printer without installing system-config-printer (error adding printer) so if you have this problem just install it

pacman -S system-config-printer

8- Add your user to sys ; lp and scanner (this if your printer is also a scanner)  groups

gpasswd --add username group

9- Install your printer driver [https://wiki.archlinux.org/index.php/CUPS#Installing_the_best_driver]

10- Use printer setting or cups to add your wireless printer. http://localhost:631/

That is all. Enjoy printing
