2. 2 Printer Controller
This chapter describes the DocuPrint IPS Printer Controller (also
called the system controller). It includes a list of component
hardware, software, and fonts, and discusses the key elements of
software operation.
Components of the Printer Controller
The Printer Controller enables you to use proprietary Xerox IPS
hardware, firmware, and software to control the printer. It has the
following major hardware components:
•
Sun UltraSPARC workstation. The Sun workstation has a
high-performance RISC processor chipset, based on the
industry-standard Scalable Processor Architecture (SPARC)
and a high-capacity hard disk drive. It contains the following
components:
— Processor
– Hard disk
– Diskette drive
– CD-ROM drive
– Connectivity boards for Ethernet and, optionally, Token
Ring
— Monitor
— Keyboard
— Mouse
• Host Channel Unit (HCU) (Channel-attached systems only).
The HCU contains the channel communications board. This is
used only when printing data received over a channel via a bus
and tag connection.
Note: Some elements and components of the Printer Controller are
accessible only by a service representative; for example, the
diagnostics for the Sun workstation processor.
Note: Printer controller hardware configurations are subject to
upgrade.
