I'm working on a licensed subscription version of ACAD15 for MAC, running on a new MacBookPro15"retinaOSX10.10 (yosemite) 

I even have a licensed copy of Acrobat Pro, and I'm not able to install a printer driver that will enable me to print to pdf at the full range of sheet sizes.  I have searched the forums and there are no resources to assist me, except for Maxim's suggestion for every user to customize page layouts.*  This is not an acceptible option.

Please advise.

Thanks,

Matt

This is a totally unacceptible solution.
