I got a Kyo TA420 installed on a W2008 R2 64 bit system. All options available (A3, mailboxes,...) When connecting printer locally on a xp system, no problems , all options available. However, when users log on a terminal server session, there are 2 possible printer connection methods : connecting by mapping with RDP session or adding printer on terminal server profile, in both cases , user cannot select A3 paper format and they cannot select mailbox output. Both server and clients use the kx driver.
