yes and no. it depends on what renderer option you are using.

in this case your resolution is restricted by the resolution of
your screen. you can make the OpenGL window as large as possible
to increase the number of pixels. with other renderers this using
a correspondingly scaled up number of pixels is needed as well.
once you have generated a (bitmap) picture you cannot zoom in
without losing resolution, this is just the nature of bitmap data.
there are some vector output formats, but they are somewhat limited
and for printing you still need to convert those into bitmaps
at some point (in the printer at the latest).
cheers,
axel.
p.s.: please have a close look at the VMD (mini) tutorials. there are
examples to teach you how to do stunning images with VMD using external
renderes.
