problems setting up hp color laserjet 4500N

[Kamaraju Kusumanchi <kk288@cornell.edu>]

Hi all
  I am having trouble setting up HP color laserjet 4500N from a debian 
unstable. The problem is that the page to be printed is shrinked to 1/4 
of the letter-sized paper. Something like

----------------
|  i   |       |
|  m   |       |
|  a   |       |
|  g   |       |
|  e   |       |
|-------       |
|              |
|              |
|              |
----------------

I am using KDE control center to set up this. The steps I followed are
peripherals -> printers -> Add printer/class -> network printer (tcp) -> 
HP color laserjet series -> test

If I choose HP laser jet series instead of HP color laserjet series, the 
output is coming on a full page (without color).

How can I get color + correct sized output on a letter-sized paper for 
this printer?

thanks for any ideas
raju
