Default printer keeps changing - second request ...

When we originally setup one of our computers it did not have a local
printer. Therefore, we assigned one of the network printers as its default
printer. Since that time, we have connected a local printer and designated
the local printer as the default printer. However, whenever we go to print
a document we find that the default printer has automatically changed back
to the network printer instead of the local printer! Any thoughts on why
the default setting is being continually changed back to the network
printer?
