“If the designers were half-smart about UI issues (like, say, Windows programers [sic]) they’d probe the local network neighborhood and omit the impossible entries. If they were really smart (like, say, Mac programmers) they’d leave the impossible choices in but gray them out, signifying that if your system were configured a bit differently you really could print on a Windows machine, assuming you were unfortunate enough to own one.”
