Update PDF
There are two distinct cases with barcode PDFs. In the first case, the PDF is
partially embedded in the barcode such that erasing the bars also erases the
PDF. In the second case, the PDF is printed entirely above or below the
barcode and is not disturbed by the barcode replacement.
Whenever the PDF is embedded in the barcode such that erasing the bars
also erases the PDF, the embedded PDF will be automatically detected and
replaced. An area surrounding the barcode will be erased to remove the
portions of the former PDF that extended beyond the bounds of the original
barcode. The erase area is shown in the figure below. Since embedded PDFs
are automatically replaced, the Upeate PDF menu option has no effect on this
type of PDF.
When the PDF is printed above or below the barcode, the behavior will
depend on the Update PDF menu setting.
• Embedded Only (default). Embedded PDFs will not be replaced. This
allows the user to keep the present PDF data and its font, etc.
• Always . PDFs will always reprint. For instance, since the original PDF will
not be centered with respect to the replaced barcode, the user may want
to always replace the PDF. When set to Always, an extra 1/6” is erased to
remove the original PDF. If the original PDF is not fully erased, it is up to
the user to increase the Ver. Erase Zone setting such that the original
PDF will be completely erased prior to the replacement being printed.
