QR Codes, Datamatrix, and TTF Fonts

Before continuing, ensure you've reviewed the background information found here on XML job submission. It would also be prudent to review the entire document for Wasatch Automation Option.

The APPENDPOSTSCRIPT tag uses the same mechanisms as the Wasatch Variable Data Printing option to allow PostScript to be specified for rendering at the end of the display list, and "on top of" background graphics.

PostScript is a rich and complex language, well beyond the scope of this document. Obtain documentation and test the solutions that you create carefully.

Wasatch SoftRIP implements a few special operators in the PostScript language to support printing of QR Codes, Datamatrix, and system fonts found in ".ttf" files. This is not extensively documented, but many developers will be able to base work on this example:

<?xml version="1.0" encoding="utf-8"?> <WASATCH ACTION=JOB> <PAGE> <FileName>/00temp/reducedPickupFile.png</FileName> <APPENDPOSTSCRIPT> /inch { 72 mul } def /Source-Serif-Pro-Semibold (C:/WINDOWS/Fonts/SourceSerifPro-Semibold.ttf) definesfntfontset 0 get definefont pop 0 0 0 1 setcmykcolor 0.25 inch 3.2 inch moveto 2 2 scale (Hello World) (version=2 eclevel=M parse) /qrcode WAbarcode .5 .5 scale 0.25 inch 1.8 inch moveto 2 2 scale (Second Hello) (rows=20 columns=20 parse) /datamatrix WAbarcode .5 .5 scale 0.25 inch 0.75 inch moveto /Source-Serif-Pro-Semibold findfont 0.75 inch scalefont setfont (Third Hello, TTF System Font) show </APPENDPOSTSCRIPT> <Copies>1</Copies> </PAGE> </WASATCH>

This sample XML will render a QR Code, Datamatrix code, and TTF font, as shown below.
