#C (27)(38)(108)#(67) <1Bh><26h><6Ch>#<43h>
# stands for the height of one row in 1/48".
•
# can have any value in the range 0-32767.
•
The distance specified by the VMI is the vertical distance moved down the page when the printer performs a
line feed. The VMI is also sometimes referred to as the line pitch.
•
If you try to set a VMI that is greater than the current length of the logical page the command is ignored.
•
Changing the VMI setting does not affect the position of the top margin.
•
The factory default setting is 8 - that is, the printer will print six lines of text per inch.
•
Depending on your model, you can change the number of lines per page setting from the printer's control
panel or remote printer console. If you change its setting, the VMI will change automatically.
