We are using ACAD 2002 and have Tahoma true type font in the title block. We plot to several devices most HP LaserJet 8150 or one Cannon iR 5000. Sometimes the font plots bold (or thick). Nothing else in the drawing is effected. It seems to be hit-or-miss and is happening on several computers but not with every drawing. I have plotted the same drawing on another machine without problem. I have checked the textstyle and it is set to normal. Any suggestions would be greatly appreciated.
