Begin by plugging the USB cable from your printer into the back of the DNS323

Connect
to the DNS323 Network Storage device and check the
status information, you can see that
the printer has been recognised and correctly identified.
[It turns out that my printer (HP PSC1210) is not a network printer, so it can't actually be installed, however, these steps should work for a networkable printer. What I did was install a similar driver to show how the process works. ]
Next step is to go to the Windows 'Add printer' mechanism.
Windows
add printer Wizard started by going to the Printers and Faxes folder first.
Select the radio button for network printer
Now select the button to browse for the new printer
Care
is needed at this point because the printer is already installed to print
directly from my computer. That's the top one that is highlighted in green.
The network printer is attached to the DLINK and is highlighted in pink.
Click the DLINK icon to open it and show the attached printer.
Once
you get the DLINK open and showing the attached printer you can click on
the printer to select it.
The
network path to the printer should appear in the top box labelled Printer,
now you can click Next to move through the installation.
Windows
XP gives you a message about the possible hazards on installing software,
if you are happy that you know where the printer driver is coming from click
Yes.
In
my case the driver was not found, so I have to go and find it.
