Do you have a printer you connect to with a local TCP/IP port instead of as a share off of a server? Wondering how the hell to get Emacs to print to it? I found
this article today that tells you how.
Basically, you create a share to the printer on your machine. You set the printer-name in Emacs to something like //YOURMACHINE/PRINTERSHARE (do I have to tell you to substitute?). Works like a charm.
