Hi folks, I have used the following code for printing option thro' windows forms.
If the document I print is just a text file, then there is no issue, it is printing it
very fine. When the document is PDF, it is not printing it instead it is printing like
the one shown here /Dest (G1046966) /Type /Annot /Subtype /Link /Border [000] ..,
what could be the reason. Is there any printer setting.. ? -One reason could be the
POSTSCRIPT, which is the base of the PDF document. -Here the StreamReader class,
which has the option of setting the Encoding.., do we need to set any encoding..., if
so what to set...? Thanks, Suki
