About The Printer
The entire system architecture of an IBM* 6400 line matrix printer is contained
on one circuit board. The use of DRAM and flash memory on this board
permits rapid access to stored printer emulations and fast processing of print
data. A variable-speed shuttle and half-step paper control enables the printer
to print a wide variety of high-volume jobs with minimum maintenance and
maximum reliability.
Although technologically advanced, the printer is easy to use. The operator
can select every printer function at the control panel or by sending printer
control codes in the data stream from the host computer.
This is also an excellent graphics printer, with optional features that simplify
the creation of dot images. The IGP** and Code V** Printronix** emulations
are simple but versatile graphics programming languages that load into flash
memory.
The IBM 6400 Series Printer Family
The IBM 6400 Line Matrix Printer family consists of pedestal mount and floor
cabinet models that print at different speeds, as shown in Table 1. Some
models are available in either floor cabinet or pedestal housings, while other
models are available only in floor cabinets.
The print speeds listed in Table 1 are the maximum speeds attainable under
controlled conditions. Actual print speed is determined by the interaction of
many variables. For more information, refer to the discussion of Printing
Rates on page 38.
