What program can I buy for my computer that I could make newsletters and brochures easily?

I have been using Printshop 20 (way outdated I know) for all of my small projects, but now my boss wants me to do her company newsletter and brochure. Printshop is not the right program for such a big job!! I need a program that I can easily e-mail the project or save to disc so that I can take it to a printing company. NOT an easy task with printshop!!!! Any suggestions would be appreciated!! Thanks!
