I have a Lexmark x5150 printer, getting error message Prop Res DLL not located when trying to print, just in Black. Contacted Lexmark, determined the Problem is Firefox 4.3 doesn't support this feature, although my browser internet explorer does.

I print shipping labels through Paypal, I want to print just in black ink, but when I use the Lexmark properties to change the printing to just black, getting message Prop Res DLL not located. Spent some time with Lexmark Chat to try and find out what I needed to do to fix this. As they walked me through a couple of things to try, one was to go to Internet Explorer, found I could do the necessary printing, with no problems of getting that error message. So it appears the problem is with Firefox 4.3
