You set your paper size in Page Setup in the lower left hand corner of the print module.

Tried that, it only lets me use 13x19 paper, also downloaded and installed new drivers.

What size paper are you trying to do?  Is it a custom size or standard?

Trying to print custom 24"wide x 21" high.

Click the Page Setup button (bottom left corner of LR Print module).  Click on Paper Size and scroll to the bottom of the list that appears and click on Manage Custom Sizes...

On a Mac, there's a +/- button under the list of custom sizes.  Click on the '+' and enter the Paper Size and margins you need.  When you hit OK, that custom size will appear in your Paper Size list from now on.
