APPENDIX (SPECIFICATIONS, FONTS AND BAR CODE)   A - 9

Bar code human readable line ON or OFF

n = 'r0' or 'R0

Human readable line OFF

n = 'r1' or 'R1

Human readable line ON

Preset:

Human readable line ON

(1) 'T5' or 't5'

(2) 'T6' or 't6'

(3) 'T130' or 't130'

(4) 'T131' or 't131'

Preset:

Human readable line OFF
All others

This parameter shows whether or not the printer prints the human readable line below the bar code. 
Human readable characters are always printed with OCR-B font of 10 pitch and all the current character 
style enhancements are masked. The factory setting is determined by the bar code mode selected by 't' 
or 'T'.

Quiet zone

n = 'onnn' or 'Onnn' (nnn = 0 ~ 32767)

Quiet zone is the space on both sides of the bar codes. Its width can be shown using the units that are 
set by the 'u' of 'U' parameter. (For the description of 'u' or 'U' parameter, see the next section.) The 
factory setting of the quiet-zone width is 1 inch. 

Bar code, expanded character unit, line block drawing and box drawing

n = 'u0' or 'U0

mm (preset)

n = 'u1' or 'U1

1/10

n = 'u2' or 'U2

1/100

n = 'u3' or 'U3

1/12

n = 'u4' or 'U4

1/120 

n = 'u5' or 'U5

1/10 mm

n = 'u6' or 'U6

1/300

n = 'u7' or 'U7

1/720

This parameter shows the measurement units of X-axis offset, Y-axis offset, and bar code height.

Bar code, expanded character, line block drawing and box drawing offset in X-axis

n = 'xnnn' or 'Xnnn'

This parameter shows the offset from the left margin in the 'u'- or 'U'-specified unit. 

Bar code & expanded character offset in Y-axis

n = 'ynnn' or 'Ynnn'

This parameter shows the downward offset from the current print position in the 'u'- or 'U'-specified unit.
