The client is using the "windows default printer" for everything but the packing slip. It is the invoices that are being redirected to other printers on the network.

It is worth noting that when launching an RDP session (remote desktop) each user has the option of having the terminal server pick up their windows default printer or having a specific printer listed on the terminal server that is always to be used for that user. I have all of the users except one using the first method. The other user has a default printer defined on the server that is to be always used for them. This printer is a network porinter and the name never changes (nor does it for any other users). This user is experiencing the same problem and they only have one printer choice available to them when logged in to the terminal server.
