Is anyone has experience with Microsoft printer drivers for Vista? Our server team would like to update drivers on all Windows print servers. As we use session printers we have to be sure that the new printer drives will not crash our Citrix servers. For example we have been using "Lexmark T620 PS3" without any problem. Now server guys would like to update the driver and replace it with "Lexmark T620 PS (MS)" which is new Microsoft Vista compatible driver. Should I expect any problem with new Microsoft printer driver or they are safe for Citrix? Thanks for any advice Zygmunt Cwalinski, System Analyst Network Services
