1> What do you mean by "cant print"? Isn't it allowed to print, or the printouts are rubbish?

2> If it is not allowed to print, that's because the pdf file is protected from printing. You can either ask for the password from someone who know it, or you can use some software to crack the password. There are tons of such softwares available, such as Advanced Pdf Password Recovery.

3> If there are some rubbish printouts, you can try to print it on another computer. If this does not work either, it might be the printer's problem.

4> What else? Is there anyone can add?
