Vertical print position 0
For the absolute vertical positioning of the print head, a distinction must be made
between the leading edges ’upper edge of document’ (top reference) and “lower
edge of document” (bottom reference). Two additional commands CSI n ! p (ab-
solute vertical positioning from the upper edge of the form) and CSI n " p (abso-
lute vertical positioning from the lower edge of the form) are available for this. A
corresponding vertical positioning of n/180 inch is set with the parameter n. For
both methods of positioning, the base line for the vertical print position 0 is on
the corresponding edge of the document.
Absolute vertical positioning (top reference):
n ≥ 1 is admissible; n = 0 causes an error message.
