Sharing a local printer on a home network...

For some reason I can no longer print from my laptop to a
shared network printer. I have properly setup the printer
but cannot access the properties. When I try to print
something I get the following error message:

You do not have permission to use the selected printer.
If you need access, contact your network administrator.

Can anyone help me with this problem? I had it working
several months ago but am wondering if I messed something
up with the network settings. Thank you.

Sincerely,

Dennis
