With this workflow component you can merge an input file with a template (both InterFormNG2 and InterFormNG templates) to create the print data stream in the ZPLII format. This can later be sent to a (label) printer, that supports ZPLII.
If you want to print, then you should normally consider to select the mimetype on your printer and use the Print component.
The ZPLII output is stored in the payload of the workflow and can later be printed out, by sending the payload to a printer.
Before running the component you should consider to set various settings for the merge via the related advanced components e.g. Set DPI.
The input payload must be an XML or spooled file. A similar component for the intermediate payload is the Create ZPL component.
To print out the ZPL you can use the Set printer component and the To printer component.
The parameter is:
Template
The template, that the input file is merged with to produce the merged output in the print data format, ZPLII. This can be a fixed value, but can also be set as an XPath expression.
