IE 5 has problems printing 8-bit palettized PNGs. The bug was fixed in =
IE 5.5 and is still fixed in IE 6 versions. The PNG you printed =
successfully was probably a 24-bit PNG, which does not trigger the bug.

Subject: [Mapserver-users] PNG file printing from browser
Hello List,
=20
I have a query about printing the map image files generated by =
Mapscript. If I try to print a map as a png image file from an IE5 =
browser it prints out incorrectly - just lots of black. I thought the =
problem might be with the browser unable to print png format but other =
png file I found on the web seem to print ok from my browser. I =
converted the output to JPEG and that prints ok but the file size is up =
to 5 times larger than png and is very slow to download.
=20
Any suggestions gratefully received.

Regards,
