Problem with installing a printer

I have been trying to install a printer on a windows 95 based desk top which has already got some few other printer drivers installed. So as usual,I followed the folowing steps;
Start|Settings|Control Panel|Printers|Add Printer
But upon double clicking the Add Printer icon
nothing happens

I tried double clicking on other icons in the control panel but realised that a few of them
donot also open.

Any help on how to get over this problem without re-installing windows?
