When I send reports in a Hp 840C printer, I'm getting, in some occasions the error :

Exepcion grave 0D en 0D 0028:C00559820 EN VXD VMCPD (01)+00000360

with others printers I dont have problems.
I'am working with VFP 6.0 and windows 98 2a. edicion.

how to resolv this error ?

Thanks very much for help me.
