It's often a problem with Printer Drivers; specific problems involving HP-supplied drivers that do not restore the state of the FPU/MMX registers on return from calls to the GDI. The solution is to use an MS-supplied driver from an OS distribution for a compatible printer rather than the HP driver, or to call _fpreset in MSVCRT20.DLL after each and every call to the GDI involving the printer driver, including report previews.
