“ESP Print Pro, by Easy Software Products, is the commercial
edition of CUPS, the Common Unix Printing System. CUPS is the
standard printing system on virtually all modern Linux
distributions and MacOS X. It runs on all Unixes, and provides
print services to Windows and *nix systems. CUPS + Linux make a
good printer server for Linux/Unix LANs. CUPS + Linux + Samba make
a great printer server for Windows and mixed LANs.“CUPS works all this magic with IPP (Internet Printing
Protocol). IPP is a client-server protocol that can run on a single
system with an attached printer, or on a server with remote
clients. You can even send print jobs to far-away remote clients
over the Internet, which sounds like a cool way to replace fax
machines. In practice I’ve had it working pretty well, but network
printing is inherently troublesome enough that you should have
someone at both locations to keep an eye on things…”
