set by an HT (C mode) ESC 0,1,2 or 3 (I mode) command.

ESC J n

FF

or ESC 4 (I mode only) ejects the document.

ESC [ J

followed by the 4 byte hex sequence 02 00 20 01 sets line spacing to 1/5 inch.

set by an HT (C mode) or ESC 0,1,2 or 3 (I mode) command.

ESC [ F

followed by 00 02 n1 n2 allows skew as follows: n1 n2 = 03 00 no skew control

 

If n1 = 01 then n2 = 00 allows 0.05 in., 01 allows 0.08 in. 02 allows 0.11 in. and 03

 

allows 0.13 in. of skew

 

Commands unique to C mode:

 

VT n

moves the document a variable number of lines or steps with n being a single byte,

 

bit coded as 01ULCCCC (C mode only) where:

 

U = 1 = Up feed

U = 0 = Down feed

 

L = 1 = Line feed (1/6” or 1/5”)

L = 0 = Step feed (1/60”)

 

CCCC = Line count or step count

 

ESC n

moves the document up (CCCC)/120 inches where n is a single byte bit coded as

 

0011CCCC (C mode only).
