CHAPTER 7 IBM PROPRINTER - 18
If bits 1 and 2 of n
4
are 01 the least significant bit of each data byte is replicated in rows 9 to 12 of the
grid.
If bits 1 and 2 of n
4
are 10 the bits 1 to 4 of each data byte are replicated in rows 9 to 12 of the grid.
Bits 5 to 7 of n
5
specify the number of columns left blank to the left of the defined character in
proportional spacing mode. Up to seven columns can be skipped.
Bits 1 to 4 of n
5
specify the width in columns of the defined character in proportional spacing mode.
Up to fifteen columns can be used to define the character.
Downloaded characters are selected using the Esc I command and then printed by sending the
appropriate character codes.

This command enables you to define and print a single line raster bit image on a single text line.

bytes of data, each byte representing a single vertical column of
4/30".
Images are printed left to right.
Images are printed at a horizontal resolution of 60 dots per inch and at an approximate vertical
resolution of 72 dots per inch.
Each byte represents a vertical column of eight dots, the most significant bit representing the dot at
the top. Simply set a bit to 1 if you want a dot to appear in that position, and to 0 if you want white
space to appear.
