If your printer in Windows Server keeps going offline even if its status says 'Ready' and you know its online try disabling SNMP on the Server.
Right click the printer and choose Properties. Under the Ports tab click Configure Port... and uncheck SNMP Status Enabled.
I have Windows 7 x64 and a 1.5TB hard drive. Whenever my PC was resuming from standby I would get a BSOD. I initially thought it was a driver issue but I came across this KB article.
"You receive various Stop error messages in Windows 7 or in Windows Server 2008 R2 when you try to resume a computer that has a large SATA hard disk"
