System Hardware
The basic hardware components of the DocuTech 128/155/180 
HLC systems are the DocuSP controller and the printer. 
The DocuSP controller
The DocuSP controller is the connection between you and the 
system. You communicate through the DocuSP software by 
selecting and managing the jobs displayed on the screen and 
sending them to the printer for production. The system also 
communicates messages and instructions to you on the Print 
Services interface screen.
The controller consists of a specially-configured workstation and 
uses proprietary Xerox hardware, firmware, and software.
Specifications can be obtained from your Xerox customer 
representative or by accessing the Setup, System Configuration 
feature on the DocuSP user interface.
NOTE:  Controller hardware configurations are subject to change 
to keep up with advances in technology.
Controller overview
The controller receives LCDS*, IPDS, PostScript, and PCL data 
streams from a mainframe host or a workstation client, processes 
the data, and sends it to the printer. The controller also provides 
the printer with print data and commands and receives status 
information from the printer. 
The controller consists of a workstation, which is run by the Sun 
Solaris Operating environment. Also resident on the controller is 
the Document Services Platform application software, known as 
DocuSP software, which manages all printing, diagnostic, and 
administrative functions on the printing system. 
The DocuSP software includes a full-color graphical user 
interface, which enables you to interact with the printing system to 
set up and configure the system, to set up and implement system 
options, to run print jobs, etc. 
Online Help (menus and buttons) provides access to online help 
that contains information when requested. 
NOTE:  LCDS is not available on the Production publisher 
configuration at this time.
