Large format Excel file conversion to single-sheet PDF

I have several versions of Excel files, tables that are from (4' H x 5' W) to (2.3' H x 8.3' W) in size when printed. These are for large format printing. It's best to convert these files to PDF first before submitting them for printing.

The problem is that I have a printer driver installed for my 8x11 laserprinter, and this causes insertion of page breaks in the Excel documents, which in turn causes the PDF file to be broken up in 8x11 pages. I want a single-page PDF that doesn't have page breaks so it'll print on as large format printer as a single sheet of paper. IOW: no page breaks.

What can I do here?
