The LaserWriter Pro 810 does not support 802.2 frame types, only 802.3 and Ethernet_II. For this printer to function in a Novell NetWare environment (and 802.2 is the default with Netware 3.12 and 4.x), the NetWare autoexec.ncf file must have an entry for one of these other protocols to support a LaserWriter Pro 810 printer.
