Because people were misusing local resources almost all access to hard drives,
printers, etc. has been disabled in browsers. The two ways around this are:
1) Write an ActiveX plug-in that is installed in the browser that can send to
the printer.
2) Either display a printable HTML page in the browser or create a PDF report
that gets downloaded to the Acrobat Reader plug-in of the browser. Then all
the
user has to do is hit the print button.
Most people choose option 2
