Does this sound right - printer installation

I contacted HP (via live chat) about where I can get drivers for my
psc 1210 all-in-one printer.  They told me to use the printer
installation wizard, select USB001 or DOT4_001 port from the list, and
then select HP Deskjet 990c from the printer list. Does that sound
right?

I just want to know if those drivers will work with my printer.  Any
ideas? I know a lot of people have had problems with the psc 1210 so I
just want to make sure things don't get screwed up. I'm not really
sure I can trust HP, the person I chatted with seemed more like a
robot than a person. And if it's as easy as using the 990c drivers,
why don't they just tell people that on their website? Seems odd to
me.

Also, I forgot to ask HP, but when should the printer be connected?
I'm supposed to use the add printer wizard, so do I connect the
printer before I start the wizard or after?
