Roman,
  It's not really a photo-copier versus laser printer issue.
  Any toner based system is going to to use the same basic principle to put
the toner on the paper.
  Whether the image gets on the drum from a laser or from a mirror
lens/optic system does not really matter.

  However, there is a large variation it the effectiveness of the different
toner engines out there.
  I'm sure there are photocopiers out there that do a much better job then
my aging HP LJ-III. I'm also sure there other laser printer out there that
do a superior job. But you just have to test them to see what works.

   My laser printer puts plenty of toner on the paper (even with the
contrast dial in the middle).

   It's just those large solid block areas. You can see this easily by
doing a test printout and holding it up to the light. The edges of the area
will be black, but as you move towards the center of the filled area it
starts turning grey. I suspect it's an issue with the printer having
problems with transferring large areas of charge on the imaging drum. All
of these systems are primary designed to print/copy text. Which they do
quite well.

  As it is the system works well, it could just use a little improvement.
