If you are talking about HP Apollo series. The driver should be there. I have a
old Apollo p-2250 and the driver is there under System>Printers. Make sure your
printer is on and hooked up to your box. Once at the Printers window. Go to
Printer>Add Printer. It should auto detect it. Printer port should say LPT#1.
Then click on the FORWARD button and find the printer under Manufacturer>Apollo.
You'll see P-2100. That is it.
In synaptic you can install
hpijs, hplip, and hplip-data and give some extra cups tools for the hp.
If you want to save some cash on print cartages. You are better off getting a HP
DJ 3940 for less than 30 bucks and works freaken better than the Apollo. The
cartages are not cheap and the reman one are not that cheap either. I came
across that it was cheaper to buy a brand new printer with cartages than buy two
for the Apollo. This is why the Apollo is now collecting dust. Besides you only
can refill them so many times before it prints %100 crap.
