Hopefully, this is right place.

We have two Kyocera FS-C8500DN at school and are doing my head in.

I have installed them on out print server running Server 2008 R2. Installed using a 64bit driver and adding a additional driver for our 32bit machines.

On the 32 bit machines the printer is working brilliant but on the 64bit side of things when students go to print A3 does not show in the list to print on yet it shows it when I click paper sizes to add a additional size.

I have tried all drivers and even contacted Kyocera (Wasn't very useful)

Has anyone has this issue before?
Thanks
