Document Conventions
This manual uses the following typographic conventions.
Convention Description
[Expression list] Items inside square brackets are optional, expression
maximum length 2*1024 bytes;
<ESC> ESCAPE (ASCII 27), control code of status
polling command, which returns the printer
status immediately, no matter the printer is
standby status or busy.
~ (ASCII 126), control code of status polling
command, which returns the printer status
only when the printer is ready.
Note: 200 DPI: 1 mm = 8 dots Font in bold and italic type is used for note.
DOWNLOAD “TEST.BAS” When displayed content is program, use Arial 10.5 sized font.

System setup commands
SIZE
Description
This command defines the label width and length.
Syntax
(1) English system (inch)
SIZE m, n
(2) Metric system (mm)
SIZE m mm, n mm
Parameter Description
m Label width (inch or mm)
n Label length (inch or mm)
Note:
200 DPI: 1 mm = 8 dots
300DPI: 1mm=12dots
For metric system, there must be a space between parameter m and “mm”.
Example
(1) English system (inch)
SIZE 3.5, 3.00
(2) Metric system (mm)
SIZE 100 mm, 100 mm
See Also
GAP, BLINE

GAP
Description
Define the gap distance between two labels
Syntax
(1). English system (inch)
GAP m, n
(2) Metric system (mm)
GAP m mm, n mm
Parameter Description
m The gap distance between two labels(inch or mm)
0 ≤ m ≤ 1 (inch), 0 ≤ m ≤ 25.4 (mm)
n The offset distance of the gap(inch or mm)
[ ]n ≤ label length (inch or mm)
0,0 Continuous label.
Note: For metric system, there must be a space between parameter m and mm.
When the sensor type is changed from “Black Mark” to “GAP”, please send the “GAP”
command to the printer first.
Eg: In DOS mode,
C:\>copy con lpt1 <Enter>
GAP 2 mm,0 <Enter>
<Ctrl>+<Z> <Enter>
Example
Normal gap
(1). English system (inch)
GAP 0.12,0
(2) Metric system (mm)
GAP 3 mm,0
(3). Continuous label
GAP 0,0
Special gap
(1). English system (inch)
GAP 0.30, 0.10
(2). Metric system (mm)
GAP 7.62 mm, 2.54 mm

SIZE,BLINE

BLINE
Description
Define black mark distance and extra label feeding length after printing
Syntax
(1) English system (inch)
BLINE m, n
(2) Metric system (mm)
BLINE m mm, n mm
Parameter Description
m The distance between two black marks
0.1 ≤ m ≤ 1 (inch), 2.54 ≤ m ≤ 25.4 (mm)
n Extra label feeding length (inch or mm)
0 ≤n ≤label length (inch or mm)
0,0 Continuous label.
Note: For metric system, there must be a space between parameter m and mm.
When the sensor type is changed from “GAP” to “Black Mark”, please send the
“BLINE” command to the printer first.
Eg: In DOS mode,
C:\>COPY CON LPT1 <Enter>
BLINE 2 mm,0<Enter>
<Ctrl>+<Z><Enter>
Example (1) English system (inch)
BLINE 0.20,0.50
(2) Metric system (mm)
BLINE 5.08 mm,12.7 mm

SIZE, GAP

OFFSET
Description
This command defines the selective, extra label feeding length, especially when you
use peeler or cutter function, this could be used to adjust the label stop position, the
extra feeding length or less feeding length could be backward pulled to adjust when
the second label is printed. This method is applied for peel-off mode and cutter
mode.
Syntax
(1) English system (inch)
OFFSET m
(2) Metric system (mm)
OFFSET m mm
Parameter Description
m The offset distance (inch or mm)
-1≤ m ≤1(inch)
CAUTION: Improper offset value may cause paper jam.
Example
(1) English system (inch)
OFFSET 0.5
(2) Metric system (mm)
OFFSET 12.7 mm

SIZE, GAP, SET PEEL

SPEED
Description
This command defines the print speed.
Syntax
SPEED n
Parameter Description
n printing speed in inch per second
Example
SPEED 4
See Also
DENSITY
DENSITY
Description
This command designates the level of darkness of printing.
Syntax
DENSITY n
Parameter Description
n 0~15
0, specifies the lightest level
15, specifies the darkest level
Example
DENSITY 7
