Set vertical tab stop........... ESC - 1B 2D 27 45 This sequence sets a vertical tab stop at the current line
position. Vertical tab stops are a function of the current
line spacing. Therefore, when line spacing changes, ver-
tical tabs remain at the same line positions, but not at the
same places on the page.
Set lines per page............... ESC FF n1B 0C n27 12 nThis sequence sets the number of lines per page and sets
the top-of-form at the current print position. The value of
variable n (0 to 182) determines the number of lines per
page. Variable n should equal the actual form length in
inches divided by the current line spacing. For example, if
the form length is 11 inches and the line spacing is 1/6
inch, 11 divided by 1/6 is 66––so n should equal 66
decimal (ASCII B, 42 hex). The number of lines per page
is unaffected by subsequent changes to line spacing.
Absolute Moving
Absolute move to............... ESC HT n1B 09 n27 9 nThis sequence moves the current print position left or right
print position to a specific print position (0 to 255) on the current line.
The value of variable n minus one defines the print
position to move to. For example, to move to print
position 5, the sequence is ESC HT ACK. Print position
0 is the far left print column. If the sequence defines a
print position beyond the rightmost print position, the
printer ignores this sequence.
Absolute move to............... ESC VT n1B 0B n27 11 nThis sequence moves paper up or down to a specific print
print line line (0 to 182) on the page. The value of variable n minus
one defines the line to move to. For example, to move to
line 5, the sequence is ESC VT ACK. Print line 0 is the
top-of-form. If the sequence specifies a line below the
last line of the page, the printer ignores this sequence.

Memo ............................. ESC @ P M 1B 40 50 4D 27 64 80 77 16-dot-high by 36-dot-wide matrix. Draft-quality
characters are formed from an 8-dot-high by 15-dot-wide
matrix.
Draft............................... ESC @ P D 1B 40 50 44 27 64 80 68
Some fonts do not contain character sets for all print
qualities. If letter-quality is selected, but the font does
not contain this character set, memo-quality is selected;
and vice-versa. If the font contains neither a letter- or
memo-quality character set, the letter- or memo-quality
Courier character set is selected, If draft-quality is
selected, but the font does not contain this character set,
the draft-quality Courier character set is selected.
