Implementing the Line Feed Function - 0o

A good technique is to exit oversized with ESC [0t and send a vertical and horizontal position absolute command:

ESC [(Pv);(Ph)f

where (Pv) is decipoints from the top print reference and (Ph) is decipoints from the left print reference. The logic seeking of the printer minimizes redundant paper motion associated with position-absolute commands. You could also use vertical position-relative to implement line feeds.

Try a line feed increment of 1.2 decipoints times the vertical expansion factor.

If you send a line feed character while in oversized, then paper advances five dot rows for the 0o rotation.
