Strictly speaking, the distinction between pure and applied mathematics is
an older one increasingly less usable today.

But pure mathematics is really the most complicated form, both graphically
and logically, so that is why one tends to return to it.

You put in this word "happily" here again: I myself try to avoid printing
out the (PS, DVI, PDF) documents I need to read because I do not know were
to store them, but I do not think the words "happily" is correct here,
since it is clearly cumbersome to read it on screen:

Experimenting with laserprinting showed that 300 dpi is too low for
displaying fonts correctly, so one needs at least 600 dpi for that. But to
be on the sure side, laser probably want 1200 dpi.

So, before that happens, it will not be possible to design documents to be
read on the screen if that is to contain the (graphical) information we are
used to on paper.
