V
parameter: Bar code vertical size, in points (like fonts).
1 point size = 1/72 inch.
S
parameter: White bars widths (has up to 4 values separated by commas)
B
parameter: Black bars widths (has up to 4 values separated by commas)
T
parameter: Bar code format number
As Barcode is algorithms-only, the user can apply the scaling independently in the X and Y
axis. In the past with standard scalable fonts, bigger size meant larger bars, resulting in a
too-wide and unreadable code, and small size meant thinner bars resulting also in
unreadable codes. Some barcodes are standardized and can not be resized.
5) The Barcode can be of any height, in the 3 to 960 pointsize range. The current cursor
position is the location of the bottom left corner of the leftmost black bar, whatever bar
code text parameter is provided. If text is to be printed by Barcode module together
with bars (P and H parameters), bars heights will be automatically adapted in order not
to overlap possibly embedded characters.
Every bar code system has default options, activated when parameters are not
provided. The user does not need to provide all parameters. As an example, if the
height is omitted, the default size is used. Every code has its specific default values,
based on international standards.
6) If required, the Barcode module prints the code value as text with the bars, either
under, half-embedded in, full-embedded in, or above the bars. Checksum and flag
characters are automatically placed in the right place for some systems (EAN 8/13 and
UPC), according to the international standards.
The Barcode module centres automatically the text and support 6 typefaces: Courier,
Letter Gothic, Univers, Univers Condensed, CG-Times and OCR-B. By default, the
Barcode module scales automatically the font proportionally to the code width and
bars height and the type of textembedding selected.
Automatic sizing limits the pointsize to 15 (no limit for text above or under bar code).
Automatic centring is done for both fixed pitch and proportional fonts.
7) After bar code printing completion, cursor is set after the bottom right corner of the
rightmost black bar.
8) If another bar code then needs to be printed, just locate the cursor to a new position
and send the barcode data. The Barcode font-like PCL sequence does not need to be
sent again.
