Printing lettered notehead problems

Aug 10, 2019

I can't seem to be able to print lettered noteheads legibly on an A4 page. It shows 150% which makes it legible on my laptop....but once printed on an A4 page (has to be A4).... you can't read the lettered noteheads at all. I'm a piano improvisation teacher and really need this facility. Any ideas on how to print on A4 page legible noteheads?
