Re: gEDA-user: gschem font scaling

[Stefan Salewski <mail@xxxxxxxxxxxx>]

I really think it is too large in printout.

You may compare a recent printout from gEDA 1.6.1 at

http://www.ssalewski.de/tmp/AmplifierCh1.pdf

with old 1.4.3 printout at

http://www.ssalewski.de/AmplifierCh1.pdf

Whenever possible, we should have access at runtime to default screen
and printout font size.

Best regards
