ESC < One line unidirectional printing
Format:
ASCII: ESC <
decimal: 27 60
hexadecimal: 1B 3C
Comment:
The current line is forced to be printed with print head moving from left to right. This
command ceases after a CR (carriage return) is received.
ESC U n Unidirectional printing enable/disable
Format:
ASCII: ESC U n
decimal: 27 85 n
hexadecimal: 1B 55 n
Comment:
n = 1 enables unidirectional printing
n = 0 disables unidirectional printing
MP 2000 normally prints text with bidirectional print head movement. This command
forces unidirectional print and allows for a more accurate text positioning.
Unidirectional printing can be useful when the ASCII extended graphic character set is
used (from 176 dec to 223 dec.), which requires the nest vertical alignment tuning.

Comment:

length equal to the set page length.
ESC C n Page length in lines
Format:
ASCII: ESC C n
decimal: 27 67 n
hexadecimal: 1B 43 n
Comment:
Page length is set to “n” lines. The range for “n” is from 1 to 127 (01 hex....7Fhex)
Physical page length is determined by the actual line spacing; maximum physical
length is 12” and if a line spacing of 1/6” is chosen, the maximum value for “n” will be
72. The beginning of the page is assumed to be the current page position. Any bottom
margin setting established by an ESC N n command is cleared whenever page length
setting is changed. Default page length is set to 66 lines.
