Hi Im building a new XenApp 5 farm based on Windows 2008 R2 (64bit) as soon as Citrix certify Windows 2008 R2. We have had lots of issues in the past with Printing in our Citrix 4/Windows 2003 environment where spoolers would crash or spool jobs were very large often flooding our WAN. Does the new Printing architecture in Windows 2008 fix these issues when combined with XenApp 5? For Optimal Printing should I invest in Tricerat ScrewDrivers or ThinPrint or is Native Windows 2008 sufficient in combination with the Citrix Universal Driver? Any gotchas or issues with x64 Printing on Windows 2008/XenApp5? Thanks Ang _________________________________________________________________ Shopping Trolley Mechanic If It Exists, You'll Find it on SEEK http://clk.atdmt.com/NMN/go/157639755/direct/01/
