>>This sounds suspiciously like a problem related to an ill-behaved printer driver; there's been an ongoing problem with drivers from certain manufacturers, notably HP, which do not handle the floating point/MMX registers of the CPU in a consistent and predictable fashion. The symptoms are a wide range of errors immediately following actions that invoke the printer driver, in many cases at the start of a subsequent call.

Yep - the HP PCL6 driver is a known problem child. I believe that there's an updated PCL6 driver available now, at least for the 4050 series, that may have addressed the FP situation.
HP didn't write the PostScript engine driver for the 4000 (thank gawd...)
