Hex Code 1B 5B p1 3B p2 20 42

Dec Code 27 91 p1 59 p2 32 66

Expression CHR$(27);“[p1;p2 B”;

Purpose Modifies the vertical (p1) and horizontal (p2) character size of all characters following the sequence and stays in effect until changed or canceled. Expansions of X3, X5, X6, and X7 are invalid for p2.

Discussion An invalid or zero parameter selects the normal (X1) expansion. If a parameter is missing, the former value is used. Valid p1 and

p2 values are the following:

X1	0-199 (default)	X5	500-599*
X2	200-299	X6	600-699*
X3	300-399*	X7	700-799*
X4	400-499	X8	800-up

* Not valid for horizontal expansion

Horizontal and vertical expansion are independent, and different values can be mixed in a line. Mixed sizes within a line are top- justified. Since the line feed is based on the size of the characters in the final pass, the largest sized characters on a line should be printed last to avoid printing over other characters.

Examples:
ESC [;200 B	X1 Vert. expansion, X2 Horiz. expansion
ESC [200;200 B	X2 Vert. expansion, X2 Horiz. expansion
ESC [800;400 B	X8 Vert. expansion, X4 Horiz. expansion

When the printer is printing vertically expanded characters, blank lines (lines with non printed characters) are not expanded from the current LPI setting.
