[10pt], {times} and tetex-3.0 : `jumping' letters at printout but not in PDF viewer

Hi, 

this seems to be really a hard problem. My document looks like this: 

\documentclass[10pt]{article}
\usepackage{times}
\begin{document}
Problem with uniform intensity. The input
data are not funny either.

Watch the words {\em uniform} and {\em input data are} above.
\end{document}


The PDF generated by pdflatex looks OK, but printed on HP LaserJet 2200 DIN
the letters start to `jump' (once again, this does not happen in the PDF itself)
: the words "input data are" almost form an arc (bridge). 

This does *NOT* happen when: 
  * using previous installation of tex
  * using [12pt] option instead of [10pt]
  * printing on other printer.

One might think this is marginal but I am just not very confortable with the 
idea that documents created by different versions of tex will look differently 
on different printers .... 

Be sure I will be most grateful for any hints.
