# Space in while printing but not viewing PDF [closed]

I am trying to write in a IEEETran class of latex. I have a very strange problem.

The minimum stripped code is as follows -

\documentclass[conference]{IEEEtran}
\def    \b      {\beta~}
\begin{document}
consumed, so the first $\b$ tokens $v_0$, then the next
\end{document}


Now when I generate a pdf using pdflatex, my PDF output looks like this -

However, when I try to print this PDF, the output looks like this - I do not understand why there is a space between v and 0. I grabbed this image, using the "print preview" of the printer. Just for complete information, I tried using HP LaserJet p4015 and HP Color LaserJet 4650 pcl3 printers.

Your definition of \b is wrong; why would you add a non breaking space after "beta"? –  egreg Jun 14 '13 at 17:16
it is because, i need a space after beta. if I don't do it, the result is beta and tokens get mixed up. –  Raj Jun 14 '13 at 17:18
I haven't observed this on my printer. However why \def \b {\beta~}, not \def\b{\beta~} (without spaces around)? –  Przemysław Scherwentke Jun 14 '13 at 17:22
I tried this, but it is the same problem. :( –  Raj Jun 14 '13 at 17:24
I found the problem with the PDF. It is the evince viewer. I am using version 3.6.0. I printed the document using acroread. And now the problem is gone! –  Raj Jun 14 '13 at 18:37
