8–5IBM Proprinter Emulation
ASCII: ESC c
Hex: 1B 63
or by sending a Soft Terminal Reset (DECSTR) control sequence:
ASCII: ESC [ ! p
Hex: 1B 5B 21 70
These sequences accomplish the same reset function. Do not use the CSI
command sequence for the DECSTR control string.
Graphics
Proprinter emulation provides one data protocol for printing graphics
information. Bit Image graphics protocol allows an image block to be
printed.
When using Bit Image protocol, you can mix text and graphics on the same
line.
Setting Bit Image Modes via Control Codes
Control codes select bit image modes. The following Bit Image modes can
be mixed on the same line and with characters:
Control
Code
Bit Image Mode
ESC K n1 n2 data
ESC L n1 n2 data
Normal density
Double density
ESC Y n1 n2 data Double density, double speed
ESC Z n1 n2 data Quadruple density
Parameters n1 and n2 together represent a 16–bit unsigned number of the
quantity n1 + 256 x n2, which equals the number of bit image characters to
follow. If n1 and n2 are programmed so that data extends past the last
character position, the data is truncated at the last character position. If n1
and n2 are both zero, the ESC sequence is ignored.
