4.2.14. Setting the vertical motion index (VMI)

Esc&l#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.

4.2.15. Setting the horizontal motion index (HMI)

Esc&k#H (27)(38)(107)#(72) <1Bh><26h><6Bh>#<48h>

# stands for the width of one column in 1/120".

•# can have any value in the range 0-32767 and can have up to four decimal places.

•If you are using a fixed space font the HMI is the horizontal distance moved across the page when the printer prints one character.

•If you are using a proportionally spaced font the HMI is the horizontal distance moved across the page when the printer receives a space control code <20h>.

•If any font characteristics are changed, or a Select Primary Font or Select Secondary Font control code is sent to the printer, the HMI is set to correspond to the default pitch value of the newly selected font.

•Changing the HMI setting does not affect the positions of the left and right margins.

•The factory default setting is 12 - that is, the printer will print ten characters of fixed pitch text per inch.
