The first thing I can quicky tell you: you must not use the printer resolution when drawing on a printer. If you use it, then something is doomed in your drawing routine, unless you want to draw at the pixel level, for example the thinest possible line (one pixel). Then you need the printer resolution, but this is the only case. Otherwise, in all normal printing routines, printer resolution is not needed. But maybe I didn't understand what you wrote... -- Benoît Minisini ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
