the subsequent pages of the document (or the next job). With pages
ready in memory, the engine continues printing as it deposits printed
pages in the output tray. (In other words, compiling, rasterizing, and
printing all work independently but simultaneously.)
User Benefit—Because print job processing time is significantly
reduced, you spend less time waiting for your documents to print.
Other printers may have multiple interface ports, but your QMS 1725
SLS Print System is unique because SIO allows
all of its interface
ports—AppleTalk, parallel, serial, and an optional interface—to be
active
at the same time.
The multiple interfaces let you connect to any AppleTalk network or
directly to an IBM or compatible PC. The printer also works in many
minicomputer and mainframe computer environments.
User Benefit—You can have more than one computer printing to the
printer. Each interface has an input buffer (which may be expanded
with additional memory) that receives data while another interface is
being used to print.
Most printers can recognize only their native command language.
However, using a form of artificial intelligence, ESP technology ana-
lyzes incoming file data from any of the printer’s interfaces, selects
the appropriate emulation from those installed on the printer, and pro-
cesses the print job.
User Benefit—When your printer is in ESP mode, you can easily
print PostScript, HP PCL 5, HP-GL, CCITT, and Lineprinter docu-
ments without changing printer switch settings or sending software
commands to accommodate different printer languages.
