A C1PrintDocument can now be exported to the new XML Paper Specification (XPS). As with other export formats supported by C1PrintDocument, there are several ways to export the document to XPS. The easiest way would be to use any of the Export methods' overloads, for example:

Dim doc As New C1PrintDocument()
doc.Export("MyDocument.xps")

C1PrintDocument doc = new C1PrintDocument();
doc.Export("MyDocument.xps");

The Export method can be invoked on the C1PrintDocument exposed by the C1Report component:

Dim rep As New C1Report()
rep.Load(…)
rep.C1Document.Export("MyReport.xps")

C1Report rep = new C1Report();
rep.Load(…);
rep.C1Document.Export("MyReport.xps");
