TI Model 855 Printer DP Emulation 6-3

Introduction

This chapter describes the Texas Instruments Model 855 Printer data
processing (DP) emulation mode. The Model 855 DP emulation
mode allows the Model 8900 Series Printer to accept and respond to
commands similar to those for common dot-matrix printers. This
mode allows the printer to emulate most of the functions of the
Model 855 Printer operating in its DP mode with the following
considerations:

q

The Model 855 DP emulation supports all Model 8900 global
commands.

q

You can select ribbon color with the command sequence ESC c n
or ESC r n.

q

Factory selected power-up defaults for the Model 855 DP
emulation are:

— Processing mode — DP

— Auto LF — NO

— The last form setting change made via the control panel is

retained and restored at power-up.

q

The Model 855 DP emulation uses standard pitch and point for
superscript and subscript characters.

q

The standard character set is the IBM PC2 Character Set.

q

The escape sequence to select mosaic graphics by setting the
MSDB to 1 is ESC v.

q

The escape sequence to cancel mosaic graphics by setting the
MSDB to 1 is ESC =.
