After some investigating I found that it is fixed and predefined in
libgeda/include/libgeda/defines.h in the gaf sources. You can change
the variable JUNCTION_CUE_SIZE_NET there to achieve your goal. This is
probably the simplest way to do it because there is no special
configuration variable to change the junction size. The difference in
size between printed and displayed junction cues was intentional, AIUI
after reading 'git log' and NEWS in the sources.

> 2.  (I asked a similar question before.)  gschem displays UTF-8 characters faithfully, but does not print them.  I do not understand how that can happen.  Does gschem use different character sets for displaying vs. printing?  Currently, the UTF-8 characters are just skipped on the printed output.  I would like to be able to print them.
The problem is outside of gschem. X fonts and printing fonts are
different and usually the printing system (ghostscript) tries to find
appropriate fonts for printing which would correspond to screen fonts.
Under some conditions (e.g. if you haven't the corresponding printing
font) your screen output and your postscript output would differ. OTOH,
the printing fonts usually contain the strict set of font symbols, and
some UTF symbols may not be presented there. There are two ways to solve
this issue. The first way is to try to change your used font in
outputted postscript file and see the result in some previewing program.
You can use this way constantly, but there is another way. If you have
found what font is appropriate for you, you can write its name to the
libgeda/src/f_print.c in the gaf sources. Look for Helvetica there and
change it to another name. The first way is simple, I use the following
command in Makefile to change outputted ps files:
  sed -i 's/Helvetica/${font}/' $(postscripts)
where my preferred font is LiberationSans-Italic.
In general, you need to find a font which meets your requirements and
use it.
