From an Apple. Netatalk supports printing from Apple clients over EtherTalk. The ncpfs package includes a daemon named pserver which can be used to privide service to a NetWare print queue. From what I understand, this system requires a Bindery-based NetWare, ie 2.x, 3.x, or 4.x with bindery access enabled. For more information on ncpfs and it's pserver program, see the ncpfs FTP site .
Most networked printers support some method of remote administration.
More usefully, there is often support for SNMP management. Typically you can find out interesting information on printer status like ink and paper levels, print volumes, and so forth, and you can usually change certain settings. SNMP printer control, and a number of other printing-related things, are being standardized by the IEEE's Printer Working Group 11.10.1. It implements the standard Printer MIB , as well as a few vendor-proprietary schemes used mainly for older devices. Both printer-discovery style actions and various printer status queries are supported.
