Mozilla-firefox printing menu non-working entries

[Mitchell Laks <mlaks@verizon.net>]

Hi,

I print using the cups printing system.
However when I try to print from mozilla-firefox and invoke print i get a 
dialog with a drop down menu that includes

hp_laserjet@:64
xp_ps_spooldir_HOME_Xprintjobs@:64
...
Postscript/hp_laserjet 

now the first ones (until Postscript/hp_laserjet) don't work and are 
incomprehensible to me.

What are they? Can I get them to work in addition to cups? 
Or else Can I at least get them  off the menu so I dont have to hunt for the 
Postscript/hp_laserjet 
in a click down menu? Where are the setttings in the mozilla-firefox package.

Clearly they seem (at least) to be related to my cups printer name.  

What is Xprint anyway? I just have figured out cups (so to speak, at least it 
works now...) .

I see Xprint on the google of mozilla-firefox. will it conflict with cups? 

Thanks,
