Why would I print with a GhostScript device?
Users print with GhostScript devices if they want to generate a file on one system and print on another. Sometimes, you get better quality printouts if you use a device that is specific to your printer, rather than using the default device (which is -dps ). Also, if you are printing to a non-PostScript printer, you should specify the type of printer driver you will be using so as not to invoke the default.
