Customers frequently ask us for drawings in PDF format. I will print to PDF from paper space in AutoCAD 2011 LT. Our usual size for alarm drawings is Arch D (24" x 36"). When you get my PDF its native size is 24" x 36". As others have mentioned you can usually get them printed out at Staples, Kinkos, or some similar provider.
You would do well to invest in a multi-function printer that will print to 11" x 17", or even 13" x 19". I saw one at Staples a few months ago, and I didn't get it because I couldn't figure out how to deep six the HP1120C without the wife catching wise :lol:. It was a ridiculously low price (lower price in absolute dollars than the HP1120C 10 years ago), and it would SCAN 11" x 17"! For a small business it would be a no-brainer. With that printer, you could tile print the Arch D print on 4 sheets and tape them together in a pinch.
