I had the same problem with my Lexmark X6170 Printer. Here is what u shoul do..
Go to the properties tab for your printer and click on the tab <Advanced> and on the button <Print processor>, select the [winprint] processor instead of the manufacturer processor (lexmark...). In the right pane select one of the [NT EMF... i have 1.008 selected] processors and this should do the trick.
ALSO disable the bidirectional support on the <Ports> tab...
This should do the trick... i have mine working for about a year now...
