You can do it a couple of ways.
I don't know your office methodology, but I usually save (multi-page) PDF's of all drawings I send to clients. They are created to print @ full scale on the correct size paper (1/4" scale on 24" x 36" paper, for example).
If I want to print them at 50% (1/8" scale), I open the PDF's in Reader (not Apple's Preview) and select, a previously created, custom paper size: 12" x 18" (that's 50% of 24" x 36").
From the print dialog, open page setup and change the scale to 50%.
Print, trim* and your done.
*12" x 18" sheets are sent to my 24" paper roll printer.
I have to trim 6" off each 12" x 24" sheet.
