Signature Capture Code
F - 3
lists selectable parameters used to generate the image of the captured signature.
BMP format does not use compression, JPEG and TIFF formats do.
Dimensions
The size of the signature capture box is determined by the height and separation of the start and stop patterns. The
line width of the signature capture box is insignificant.
line width of the signature capture box is insignificant.
The thinnest element width, referred to here as X, is nominally 10 mils (1 mil = 0.0254 mm). Select this as an exact
multiple of the pixel pitch of the printer used. For example, when using a 203 DPI (dots-per-inch) printer and
printing 2 dots per module, the resulting X dimension is 9.85 mils.

Data Format
The device output is formatted according to
. Symbol devices allow different user options to output or
inhibit bar code type. Selecting "Symbol ID" as the bar code type for output identifies the CapCode with letter "i".
