paperMatch

Match paper to page size.
[read/write property] paperMatch([out, retval] VARIANT_BOOL *match) paperMatch([in] VARIANT_BOOL match)
If this property is true, the paper size will be matched to the PDF page size, for each page.

If this property is true, it overrides the paperID, customPaperWidth, and customPaperHeight settings.

resetParams resets this to its default value, which is to print to the printer's default paper size.
