These commands move the print position to the right or to the left of the current position in the
amount you specify. Underline characters don’t print in the space between the two positions.

These parameters represent a four-digit ASCII number for the value of the amount of movement
to take place. If the value you wish to assign is less than four digits, use zeros for the first
digit(s). The actual amount of movement depends on the pitch engaged:
Table 59: ML ESC % F and ESC % E Commands —
Movement Increments for Pitch Settings
Pitch Movement Increments
10 cpi 1/120"
12 cpi 1/144"
15 cpi 1/180"
17.1 cpi 1/206"
20 cpi 1/240"
Proportional Same as the corresponding value for each cpi
For example, suppose you have your pitch set at 20 cpi and want your printer to move 1" to the
right. From the table above, at 20 cpi your shift will be in increments of 1/240", so the value of

would be 0240 (1" / 1/240"). Send the BASIC statement

Note: If you send a location value outside the set left or right margin, this command will be
ignored.
