Net Use LPT3: port disconnects

Hello,
A program that we use prints only to LPT pritner ports. To create such port we use the command “Net Use LPT3: \\\ /Persistent:yes”

Now, we use computer name instead of server name because the computer is installed on the local computer and shared. The problem that we are having is that within a couple of days the port gets disconnected. When the NET USE command is used, the status of the port is “DISCONNECTED”. To fix this problem we have to delete the port and recreate it.

Is there something that can fix this problem from ocurring?
