Chapter 2 Native Emulation Commands 66 260071 ‐ 001A
ORDER BIT of the above control codes to allow the printer to distinguish between encodable
data and string terminators.
POSTNET DC4 DC4 ESC ! n24pEM
The POSTNET bar code data fields contain only numeric data and do not have a defined
format length. POSTNET bar codes have no printed HRC string. The LOW/TALL bars that
encode the symbol comply with the U.S.P.S standard regardless of the p field value.
DC4 DC4 ESC (GS
Prints bar code symbols.
ASCII Code
DC4 DC4 ESC (GS n1 data GS n2 data ... EM
Hexadecimal Value X'14' X'14' X'1B' X'28' X'1D' n1 data ... 19
Decimal Value 20 20 27 40 29 n1 data ... 25
Range 1 = n = 12
0 = p = 1
This sequence prints the bar code symbol according to the previous selection. If you want to print more
than one bar code symbol of the same type and height, GS n defines the distance from the beginning of
the line or between two bar code symbols in multiples of 1/60 or 1/90 of an inch, depending upon the
selected barcode density (120 or 180 dpi). At the end of the line EM must close this command.
Miscellaneous
DC4 DC4 ESC @
Re-initializes the printer.
ASCII Code DC4 DC4 ESC @
Hexadecimal Value X'14' X'14' X'1B' X'40'
Decimal Value 20 20 27 64
This command resets the printer mode and clears the buffer of printable data.
DC4 DC4 ESC J
Sets amplification factor.
ASCII Code DC4 DC4 ESC J hv
Hexadecimal Value X'14' X'14' X'1B' X'4A' hv
Decimal Value 20 20 27 74 hv
This command sets the required amplification factor to be applied to the current font.
h
It is the horizontal amplification factor; the value range is 1 to 4. It is applied to the basic symbols.
It is the vertical amplification factor; the value range is 1 to 4.
0 values for either the hand vparameters keep the related current amplification factor unchanged.
The internally available symbol's amplification algorithms support the following character attributes that
may be selected by means of the available control sequences within the currently active emulation: double
width, double-height, emphasized, double strike, subscript, superscript, italics, proportional, and
compressed.
Doublewide and double-high attributes must be lower than 2.
