User Benefit—When your printer is in ESP mode, you can easily
print PostScript, HP PCL 5e, HP-GL, or Lineprinter documents with-
out changing printer switch settings or sending software commands
to accommodate different printer languages. Other optional emula-
tions are also available.
The QMS 2425/2425 TURBO Print System prints almost any file sent
in a language ESP technology understands, whether you have one,
two, or more hosts, and whether you are communicating through an
Ethernet, Centronics or bidirectional IEEE 1284 parallel, or other net-
work interface. Most users never have to change from ESP mode to
another mode.

Although many other printers have multiple interface ports and auto-
matically 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—Ethernet, parallel (Centronics and bidirectional IEEE 1284),
the optional serial interface, and one other optional interface (Ether-
net, Token-Ring, DECnet-TCP/IP, or LocalTalk)—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.
The standard interfaces let you connect to any Ethernet network or
directly to an IBM PC or compatible. The printer also works in many
minicomputer, mainframe computer, Macintosh, and network environ-
ments.
User Benefit—You can have more than one computer sending print
jobs to the printer. Each interface has an input buffer (which may be
expanded with additional memory or an optional hard disk) that
receives data while another interface is being used to print. This frees
the host computer faster, reduces network traffic, and increases
throughput.
