Printing transparent png on postscript printers

S

Hi all,

in our company we are developing a postscript printer driver. We have office
documents which have transparent images (png) in the documents (examples in
word and powerpoint available).

As in the Articles 904948 and 815001 are reported, these files produce a
very large postscript-spoolfile with our driver. This effect was tested with
Office XP and 2003. This behavior is dependent on the system. We have 2
systems with Office XP and WinXP SP2 nearly the same configuration. But the
office documents on both systems produce different spoolfiles sizes (for
example 6MB and 200MB with the same file). We using this in an office
automation environment so the workaroun d with cut & insert as png doesn't
solve this problem for us.

For me it seems that the systems differ in only one system setting. And my
question is, what could this setting be? I've checked GDI-Dlls, IE, Office,
WinXP Version and everything has the same version. So could it be that there
is a system wide flag which handle "transparent-handling" for the office
products?

Thanks for your help.

Daniel
