OK, then the printer is not assinged to the VM.

There seems to be no HL-W2130, only a HL-2130 which is only a printer, 
so everything about the scanner would be unrelated.

Of course reinstalling would be an option - don't forget to backup your 
valuable data if you decide to go that path. But probably it is only a 
problem with a missing package or a bad configuration, especially if you 
can't find ANY printer. Which Ubuntu version are you running and is it 
the same on all the machines?

I'm not sure if there is another program apart from CUPS. But maybe the 
automatic printer detection fails for some reason, so you could try to 
start the CUPS user interface at <http://localhost:631/admin>.  There 
you could install a new printer and you should be able to find your 
network printer (samsung CLP-320N). It will ask for username and 
password - use the credentials which you use to login to the machine.
