Introduction
This chapter provides additional technical information on memory 
management, end job mode, the PS Protocol option, and HP-GL 
color-to-grayscale conversion.
Printer-Host Communication
Interface
An interface is the point at which two elements connect so they can 
work together. A printer-host interface is the way a printer connects to 
and works with a host (a microcomputer, workstation, minicomputer, 
mainframe computer, or network), and it involves both hardware and 
software. The way your printer interfaces with a host depends on 
many things, including computer type, computer ports available, inter-
face cabling, application software, printer emulations, and printer driv-
ers.
Simultaneous Interface Operation (SIO)
Simultaneous Interface Operation (SIO), a standard feature of QMS 
Crown architecture, enables your QMS 1660E Print System to 
communicate simultaneously with hosts through the parallel, serial, 
Ethernet, and optional interface ports. In other words, SIO allows you 
to have more than one host communicating with the printer at one 
time. 
ESP Technology
Emulation Sensing Processor (ESP) technology is another standard 
feature of QMS Crown architecture. ESP technology, which works 
with most popular commercially available applications, uses a form of 
artificial intelligence to analyze incoming file data and select the 
appropriate printer emulation (for example, PostScript emulation,
