A:
The built-in the printer driver doesn't have any output options. It simply captures the spool file (i.e. the XPS) and converts it to PDF. The only way to control/affect spool file generation is via standard Windows print API or by modifying the information that the source application is sending to the printer device context. Once the file is normalized to PDF you can easily add all the required options in a post-processing step.
For example, you can encrypt PDF by setting the security handler (as shown in EncTest sample) and save the file with linearization using doc.Save("out.pdf", SDFDoc.SaveOptions.e_linearized)
... or you can apply watermarks (as shown in Stamper sample, http://www.pdftron.com/pdfnet/samplecode.html#Stamper),
… or down-sample images (as shown in Optimizer sample, http://www.pdftron.com/pdfnet/samplecode.html#Optimizer) etc.
To adjust colors & path line weight you would use the approach shown in ElementEdit sample (http://www.pdftron.com/pdfnet/samplecode.html#ElementEdit, you would be modifying SetLineWeight() in element.GetGState()) and so forth.
