Hi Martin
Thanks for your reply - I did as instructed and tested it again and, unfortunately, it makes no difference.
Also, I've been told that when printing multiple copies from Excel, using the PCL5e drivers, any underlining is ok on the first copy and disappears from the other copies.
We have got the latest copies of the PCL6 and PCL5e drivers on the system at the moment.
Do you have any more ideas? Thanks.
