5-22 — 5. Bar code and enlarged character function —
(12) VMI for enlarged characters: DC4 DC4 j
Format: ASCII DC4 DC4 j n1 n2
Hex 14 14 6A n1 n2
Decimal 20 20 106 n1 n2
Function: Specifies the VMI (vertical motion index) of enlarged
characters.

The VMI indicates the distance between two lines, i.e., the length the print
head moves after printing one line.
The VMI is (n1 + n2 x 256)/180”. The MSB of parameter n2 is masked.
The VMI can be set to zero.
The VMI is not dependent on the length expansion of enlarged characters.
After specifed command have priority over DC4 DC4 j or DC4 DC4 o.
The VMI is invalid and the cell offset 6 line feed pitch is selected (i.e., 1/6”
x cell expansion) by default.
(13) Setting and canceling the enlarged character mode: DC4 DC4 l
Format: ASCII DC4 DC4 l n
Hex 14 14 6c n
Decimal 20 20 108 n
Function: Sets and cancels the enlarged character mode.
n = 00H,30H: Cancels the enlarged character mode.
01H,31H: Sets the enlarged character mode.
The MSB of the parameter is masked. Any sequences other than the above
parameters are ignored.
When the enlarged character mode establish command is issued, the special
effects, character pitch, line feed pitch, length and width double-size
printing settings specified for the emulation become invalid the enlarged
character mode is canceled.
When the enlarged character mode starts, characters are printed in the
conditions selected when the enlarged character mode was last canceled.
If there are non-enlarged characters or bar codes when enlarge character
data is input the non-enlarged character are printed.
In the enlarged character mode, automatic printing is not performed if the
printing position exceeds the right margin. Excess data is abandoned and
the printing position is set at the right margin when the right margin is
exceeded.
If the right margin is exceeded while a single enlarged character is being
printed, the character is printed up to the right margin.
