PostScript language Licensing issues for Adobe Companies

The Great God of you:

Recently the company intends to use PostScript language to develop a printer product, I am now on this aspect to understand, but about PostScript but know nothing, ask the big God in the garden have not known.

I would like to ask you about the licensing of a programming language that Adobe introduced in the 80 's when the company was first established. The intention is this: our company recently in the development of a product, product design to the PostScript language development, and I learned from the online information, Adobe Company in 1997 launched the last version of PostScript PostScript 3 has not been updated again, when other companies used postscript to develop products, Adobe is to charge a portion of the patent fees, in recent years do not know what the situation. I wonder if you know the specifics of the PostScript authorization. I'm in trouble, everybody.
