Set Relative Position (ESC \)
1B 5C N1 N2
This control moves the print head to a horizontal print position relative to the current print position using
1/120 inch increments. To calculate the correct values for N1 and N2, determine the displacement required
in 1/120 of an inch. Send the resulting number using the formula total number of dots equals N1 + (N2
×
256). If the desired formula is to the left, subtract the number from 65536 before using the formula. The
print head will move (N1 + [N2
× 256])/120 inches relative to the current print position. The control is
ignored if it would move the print head beyond the page margins.
Set Letter Quality Justification (ESC a)
1B 61 NN
This control selects print justification according to the following values of NN:
0
Selects left justification
1 Selects center justification
2 Selects right justification
3 Selects full justification
Notes:
1. Left justification is the default setting (NN = 0).
2. The commands HT and BS are valid only when left justification is active.
3. For full justification, there must be no carriage returns within a paragraph.
Select Vertical Tabs in Channels (ESC b)
1B 62 CH N1 N2...00
This control sets vertical tabs to channels selected by the Set Vertical Tab Channel (ESC /) control. The
value of CH is 0 through 7 and the value of N1 is 0 through 255.
The distance of each tab stop from top of form is the current line spacing times the number of lines given
in N1.
If paper movement is commanded to a value of N1 greater than the page length, the paper movement
command is ignored. The values of N1 must be in ascending order. If they are not, the sequence up to
and including the out of sequence number is ignored. Skip over perforation is ignored. You can clear any
channel by sending ESC b CH 0, where CH is the channel number.
Relative Move Right n/120 (ESC d)
1B 64 N1 N2
This control spaces forward in 1/120s of an inch. To find the values for N1 and N2, determine the required
displacement in 1/120s of an inch. Send the resulting number in the formula: N1 + (N2 X 256).
Relative Move Left n/120 (ESC e)
1B 65 N1 N2
