When printing a paper space viewport in Conceptual Visual Style mode, text objects are visible in the print preview but not in the printout on paper. Why are they not hidden in the preview if they are not going to be printed?
Are you using TTF? Change to SHX fonts and see if your issue goes away.
What are you printing to? Using what driver?
SHX fonts do not solve the problem.
Printing to various printers/plotters, all have the same problem.
