Hi,
I've looked in the forum but can't see an answer to my (basic) question.

I've downloaded the large .pds map file. I have acrobat 8.0, but I can't figure out how (if indeed it is possible) to print it on A4 sheets.

The print or print setup in acrobat seem to only allow me to print the whole giant image on one sheet. Is there a way to split it onto (many, many) A4 sheets.

If not, what's the best way to do the same thing with the PNGs? I have photoshop 7.0, but I don't see a means of doing it there either.

Any help much appreciated.

What about the following?

Get if full-size on your screen, so you only can see a part of it.
Press the "print screen" button and paste it in something like Paint.
Now you create from it a A4-size part of the map, what you can print out.
Repeat it many times, till you have covered the whole map.

Unfortunately Adobe Reader don't support this
You must first split the map and then print each page individually.
You can get already split image files in the Archive
