Acrobat has security settings that allow the document creator to limit the way a document is used. Security can limit file entry, printing, print quality, copying text/pictures, and much more.
The document you are trying to print must have security settings so you cannot print. The company probably wants to protect some copyrights so that assests on the brochure are not illegally reproduced.
Call the company and ask for a hard copy.
