Question / Problem:
Can Mixed A3/A4 be set as the default paper size in the Kofax Front Office Server (KFS) 4.x Hewlett-Packard (HP) OXPd 1.6 MFP Client?
Answer / Solution:
Unfortunately, OXPd 1.6 does not expose the Mixed A3/A4 paper size option to third-party apps such as the KFS 4.x OXPd 1.6 MFP Client. Therefore, it cannot be set as the default paper size in the client. This issue has been documented in TFS 587688.
