Apple does not maintain a list of third-party AppleTalk printers that may be hidden with AppleShare IP. The process, using an industry-standard PostScript command, is the same as when capturing an Apple LaserWriter.
AppleShare IP uses a PostScript operator to change printers' AppleTalk Type; thereafter, the printer will not respond to NBP Lookups from and won't be visible to client Macintosh computers. The print server will know what printer's current AppleTalk Type, having changed it, and will be able to locate, open up a connection, and print to it.
If a printer or RIP, possibly used in combination with an optional network interface, doesn't support fully PostScript and the "appletalktype" PostScript operator, then the hide feature may not work. If you encounter such a device, you may wish to check with the manufacturer of that device to verify compatibility with this operator.
