I don't understand the earlier reviews listed on this product. I have used the original Poster Print Program on my G4 Mac Cube and it ran perfectly.

Today I updated to the 3.0 version on my G5.
Running Tiger OSX this program is flawless.

The quality isn't effected at all wether when you enlarge the poster, to ANY SIZE. The size constraints are unlimited, unlike Tiler, and other such programs. Poster Print allows you to use several different types of measuring devices, Inches, Pixels, Pages, Centimeters etc.

You can use any type of picture file, JPG, TIFF, etc.
You are not limited to just a PDF such as in Tiler.
Also Poster Print will mark the pages with cutting
points, there is no guess work as to where you should make your cuts when creating posters.
This is an excellent tool if you need to create
Larger than normal images with little to 0%
loss in picture quality

It is well worth the expense of a mere $17.90.

Granted Tiler is Free, however it is very limited
and the quality just isn't there. Bottom line you
get what you pay for.
