Horizontal cursor positioning - columns

Esc&a#C (27)(38)(97)#(67) <1Bh><26h><61h>#<43h>

# = number of columns

•A plus or minus sign preceding the number of columns parameter indicates that the cursor is to be positioned relative to its current position. A signed positive parameter value signifies that the cursor is to be repositioned to the right on the page, a negative value means that it will be moved to the left.

•An unsigned number as the parameter signifies that the horizontal repositioning is absolute - the cursor will be repositioned the specified number of columns to the right of the left edge of the logical page, the PCL coordinate system’s y-axis.

•The parameter value can have up to two decimal places.

•The cursor’s vertical position remains unchanged.

•If you attempt to move the cursor to a position that is outside the boundaries of the logical page, the cursor will be positioned at either the left or right edge of the logical page as appropriate.
