Introduction
Printer Features
The QMS 3825/3225/2025 Print System offers a unique combination 
of high-performance processing, network/host connectivity options, 
innovative network features, and paper handling features. Your 
printer can interface with any IBM PC or compatible and any Macin-
tosh, plus most mainframes and minicomputers. 
This overview outlines your printer’s major features and their benefits. 
Specific chapters contain more information on each feature. Consult 
the index or table of contents for guidance in locating this information.
QMS Crown Technology
QMS Crown is a proprietary multitasking printer operating system, 
which allows QMS to adapt advanced printer software to the evolving 
printing needs of users in many different environments. 
Crown’s multitasking capability allows your printer to process and print 
jobs simultaneously instead of sequentially, by using advanced mem-
ory management techniques, such as simultaneous interfacing, emula-
tion sensing processing, input buffers, job spooling, compile-ahead 
processing, compressed data formats, error recovery, user-config-
urable memory clients, context switching, and spooling spillover.
Simultaneous Interface Operation (SIO)—Although many other 
printers have multiple interface ports and automatically designate 
a “hot port,” only one port actively receives data at a time. Your 
printer is unique because SIO allows all of its interface ports—
LocalTalk, parallel, serial, and an optional network interface—to 
be active at the same time. You can have more than one host 
computer printing to the printer. Each interface has an input buffer 
that receives data while another interface is being used to print.
Emulation Sensing Processor (ESP) Technology—Most print-
ers can recognize only their native command language. Your 
QMS printer, however, has ESP (Emulation Sensing Processor) 
technology. Using a form of artificial intelligence, ESP technology 
analyzes incoming file data from any of the printer’s interfaces. 
ESP technology, which works with most popular commercially
