I am on Mac, OS 10.6.8. I am unable to print consistently from my 8560 DT, connected to a network. My firmware and drivers are up to date. There are several problems, but they all boil down to the fact that my computer has trouble communicating with the printer. If I restart the printer, I can usually print one or two copies, before it gives me the message "network host '188.8.131.52' is busy; will retry in 30 seconds..." or 5 seconds, or 20. But it never connects.
Latest patches & drivers installed, USB Wait Timeout =999, dragging USB_PostScriptTBCP_rev2.ps & TEST_USB_PostScriptTBCP.ps to print queue window solves problem for the next few documents but then the errors creep back in again.
Today, even dragging & dropping the .ps files gives me "error:undefined (command type:nametype)" pages.
If I could send this printer back I would at this point.
