He could Richard , Keith is from the Mother Country   This is a deliberate crippling on HD Pro Keith  , max. size you can Print too is 18"X24" or Architectural C - 18" x 24"  (or Ansi C at 17"x22")   http://www.homedesignersoftware.com/support/article/KB-00539/181/Home-Designer/Printing/How-are-the-Architectural-and-ANSI-paper-sizes-different.html     The Workaround is to print to PDF at 1/2 your normal scale , and then have the File printed at 200% at the Copy Shop to double the scale back up to the needed scaled.   Note you are not printing at 18x24 for this...   ie  1/8"=1' scale  on 12x18   printed at 200% is 1/4=1' on 24X36 (Standard Arch.D Paper)   Ansi sizes 1/8"=1' scale  on 11x17 (ansi B )  printed at 200% is 1/4=1' on 22X34 (Standard Ansi D Paper)       2015 allows Printing direct to PDF but earlier versions need a PDF Printer Driver , usually PDF995 is with HD titles and works well , I use it for all sorts of Printing to PDF especially if emailing something . CutePDF is another free PDf Driver but it Adds other programs to your computer too , at least it did when I tried it several  months ago , it added Comodo Dragon a web Browser and other crap, so I went back to PDF995 which shows a splash screen as it "prints" but is harmless other than that. http://www.homedesignersoftware.com/support/article/KB-00484/181/Home-Designer/Printing/Generating-a-PDF-File.html   you don't have to send to layout 1st , most views can be printed directly as can the whole page but if you are sending to layout , set the plan View window to Print Layout/Preview before sending it so you can see if it is going to fit on your page.....make sure "show drawing sheet" is checked in the Print DBX 1st.  more info in this post I did a while back https://chieftalk.chiefarchitect.com/index.php?/topic/1253-dimension-size-on-layout/#entry9849   There is a KB Article on printing to scale too, but on Imperial plans the default is 1/4=1'  though that is often too big esp. if printing to 8.5x11 paper though I have started using 11x17 landscape (also called tabloid) which works better if your printer can handle it.     this is then doubled to 22x34 if needed.   https://chieftalk.chiefarchitect.com/index.php?/topic/1253-dimension-size-on-layout/#entry9849      You can create different sized layout pages for different sized papers if need , just make sure your printer is setup 1st ( page setup) so it sends to the right size.   hope this will get you started   Mick.
