A 133-MHz PowerPC processor oversees print engine operations and PostScript image
processing. The printer features an integral bi-directional parallel port (IEEE 1284C with
ECP mode) and a 10BaseT Ethernet port (with support for EtherTalk, Novell
NetWare/NDS, TCP/IP, DHCP and Windows Peer-to-Peer). A USB high-speed serial port
is also provided. A rear panel slot allows customers to install one "smart card"
PhaserShare Series B Network Card. One card provides a LocalTalk port. A second,
alternative card offers a 10/100BaseT/10Base2 Ethernet board providing standard
protocol support for EtherTalk, Novell NetWare/NDS, TCP/IP and DHCP. When
installed, this card disables the standard 10baseT port. A third card provides a Token Ring
board providing protocol support for TokenTalk, Novell NetWare/NDS and TCP/IP.
When inserted, this card also disables the standard 10baseT port.
A second rear panel slot accommodates an internal IDE hard drive for print job collation,
job accounting, and font storage.
The printer features Job Accounting, which maintains from 50 to 5000 records of
processed print jobs, depending on memory options and hard drive options. The record
contains information such as time and duration of the print and the percentage of color
coverage on the print. The log of records can be retrieved using PhaserLink, PhaserShare
or CentreWare IS software.
