From various applications, I keep printing blank letter-size pages to Xerox 7750 and 8850 printers from applications such as Word or Safari. Generating a PDF, I can see why. Documents are scaled to 65 x 42" landscape, making the upper left corner white. How do globally reset default page size to 8.5" x 11"? Note: Print & Fax Preferences "Default Paper Size in Page Setup" is "US Letter." iMac Intel Core Duo Mac OS X 10.4.11 (all updates) Thanks in advance.
