Trouble printing on home computer printer

Unfortunately, it's difficult for us to troubleshoot all kinds of PCs and printers - there's so many combinations.  By default, the page size is always 5 1/2 x 8 1/2.  But if you print to your PC printer from Adobe, your print settings may be set to full page or other.  If you play with the settings, you should be able to print "booklet" size or 1/2 pages on your larger sheet of paper.  It's something in how you have Adobe or your printer settings.  Try to only print one page for testing.  Also, try Googling your printer and printing a PDF like a booklet.
