I do this command
cat /etc/hosts
192.168.2.52 br2_warehouse
192.168.3.10 br3_sales
192.168.3.50 br3_office
192.168.3.51 br3_counter
192.168.3.52 br3_warehouse
192.168.4.51 br4_counter

How do I delete the printer "192.168.3.50 br3_office" ?

I have no idea what you're asking here. Are you asking how to edit /etc/hosts?

sudo vim /etc/hosts
i
delete the line
ESC
:wq

If that's the goal, sed would be a lot quicker.

sed --in-place '/192.168.3.50 br3_office/d' /etc/hosts

or awk. Or lots of options xD vim works as well of course, but even there no need to go into interactive mode... just vim, arrow down to the line, then dd, then :wq.
