Printing colored read only files.

Greetings,

 

I receive .dwg file types that I open in Draftsight. Often these are read only drawings with black backgrounds and yellow and pink dimensions.   They do not print well at all!  What options do I have to change the drawings to all Black bold lines? If I just set my printer to use black ink only I get faint dotted gray for the colored dimensions.

 

Thanks,

Tim Johnson
