Did you go to HP and get the drivers for Linux? HPLIP. I have a similar setup,
but a different HP Printer. After I installed the driver, it found the printer.

How do you install drivers using Gnome?

You dont install wireless drivers to print wirelessly.

Your printer or your wireless print server is just like your laptop in
that, it has a wireless card. It receives wireless signals. You set up
the printer to communicate with either your wireless router (which
presumably connects to your DSL line) or you set up your computer to do
so. The printer will put off a signal which in your wireless screen on
your computer should say something like "Epson310" or something similar
identifying it.

Wherever possible it is best to use the repositories because what can be easily
installed can be easily removed. HPLIP is in the repos. Many drivers are
included with the kernel, but if you install Gutenprint and Foomatic, along with
CUPS you get most of them. Some are also found in the miscellaneous text based
sections. For example, my Brother laser printers are there. It is rare to have
to go outside to get them with any distribution and especially with Ubuntu which
has such large repositories.

Always check out the repositories and search there before going to an outside
source. It is the Linux way. Searching the net is the Windows way.

I have gotten most of my info off this list or from the Ubuntu sight. Gee I
didn't know about that it was not the "thing" to do to get from the retailer.
Oh, well. Isn't it a good thing that companies are making drivers for our
hardware? Still trying to learn.

That's great that you are learning and posting here. I just want to keep us
all on the same page. Linux has its own way of doing things. When you
install Windows you need to feed in driver disks afterwards and Windows
users expect that this is universal. But, Linux includes most drivers with
the kernel. Some are provided by manufacturers like HP and others are
provided through reverse engineering by the open source community.

There are a few exceptions. If you cannot find a Linux driver for some
wireless cards and some printers there is a workaround that allows you to
use a Windows driver.

It is the same for applications. Most Windows people go to the store or
search the internet for programmes. We don't, partly because the store
option is not available and partly because Linux users expect controls. So
software is stored in repositories that are maintained and free of malware,
viruses and trojans. If only the Windows world worked this way, then those
users might have fewer problems. When Windows users come to Linux they bring
Windows habits and thinking. We expect that and so we try to show them that
things are done differently.
