Thank you very much, Delfos.
It's good to know I did do nothing wrong.
Probably, I need to use GIF instead because the background map is
actually Google Maps.
By the way, did you try PNG24 as well? The same results?
Thanks,

Hi Ei,
I don't have a solution, but it might be helpful to know that this
problem has existed for quite a while in Mozilla (>2 years). It's
nothing to do with your particular setup or printers, I have had the
same issue here.
Perhaps you could merge the images into a single image? This is what I
do for my print layouts.
Regards,
Jacob

Subject: [UMN_MAPSERVER-USERS] Firefox can't print
transparent PNG image from Mapserver
Hi guys,
This may be a Firefox issue but want to know how you guys
deal with this
problem, if any, on your mapper application.
I got a weird problem that Firefox can't print a PNG image with
transparent background which is retrieved from Mapserver.
It's transparent on the browser, and so is it with [Print Preview].
But when I print this, the PNG image covers the legend and background
images (the transparent background turns to white).
To make things simple, I copied the PNG image in question along with
legend and some background map images into a quite simple HTML.
http://seamap.env.duke.edu:8888/dev/mapservice/googlemaps/test.html
Here, the combination of points and lines is the PNG with transparent
background. Should look OK on your browser.
Below is a screen shot of Firefox's [Print Preview].

int_png.jpg
Still has transparent background, but when printed, it doesn't.
IE doesn't have this problem. It prints as seen on the browser.
Do you have any idea what's wrong?
Is it just a Firefox bug? Any workaround? Should use GIF?
# I thought Firefox provided great support for PNG...
