	mode; n/360 inch in A793 emulation mode
Range of n:	0–255

Prints one line from the buffer and feeds the paper n/8 mm (n/203 inch). The line height equals the character height when n is too small.

If the set horizontal and vertical minimum motion units command (1D 50) is used to change the horizontal and vertical minimum motion units, the parameters of this command (print and feed paper) will be interpreted accordingly.
