All UniPrint products are available for free download. When you download any of these products, they are fully functional except that there is a banner / watermark printed diagonally across the printout. (The only exception is UniPrint client software, which is a complementary product to the core products.)
You can request a temporary license that expires in a predetermined date, usually within 30 or 60 days. With the temporary license, you can evaluate the UniPrint product of your interest, and it behaves exactly the same as the fully licensed version. When you are ready to order, you need to call a reseller or a distributor to get a license key.
