Inverted colors in Printouts

Hi All!

In a particular machine connected directly to a printer, when taking printouts from SAP B1 the colors are getting inverted, like the areas of White are converted to black and Black to white.

This happens only when taking printouts from SAP B1 irrespective of users login and specific to a particular machine.

Not happens in the machines connected in the network when the printouts are taken from the same printer.

Guess any reason??

Thanks,

Raj,.
