I have a printer at my office that is connected to a local network and my linux box at work can see it on the network. However, it is not visible to the outside world.

I was trying to figure out a way to add it on my MacAir and so far have found two options:

1) Using ssh tunnel via CLI: cat file.pdf | ssh user@linuxbox lpr. 2) With Chrome installed on the linux box, using the Google Cloud Print service on the remote box and automator on my MacAir I can add the printer to Cmnd+p dialog box

I like the first method since it does not require Chrome be installed and the second one since it allows to use Cmnd+p inside all applications. I was wondering if there is a way to combine by using automator to run the first command line script.

What about port forwarding? Is it possible to forward the remote CUPS 631 port to a local port and then add the printer normally? What other methods would you recommend?

Are these two descriptions (1) 'my office' and (2) 'at work' describing (a) one and the same place or (b) two different locations? -- Is your MacAir trying to access the printer from the network describing '(1)' or the network describing '(2)' or the location describing '(3) the outside world'? – Kurt Pfeifle Jul 3 '12 at 13:56
@KurtPfeifle My bad. Work and Office are the same place, i.e. linux box is connected to same network as the printer. My MacAir, however, is on a separate network (say home) which is "outside world" to the local network at the office. – GradGuy Jul 3 '12 at 19:08

3) Install cloudprint on the Linux machine.
