Horizontal position 

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.



coordinate system's y-axis. 



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.
