We have a single print server running Server 2008 R2 64bit (virtual server running on Citrix XenServer 6.1). Everything has been working fine before they went on summer vacation. Coming back we have certain printers that no one can print to *except* the print server itself can print just fine. This includes their RDS farm (Server 2008R2 64 bit VM's) and individual systems that install drivers too (like laptops and desktops that use the print server, they all run Windows 7 Enterprise 64 bit.) Any ideas where to look? All printers are supported on server 2008R2 (and 2012), fairly new (2 years old at most), and all IP connected.
