We are trying to troubleshoot why several of our computers with "SNBC BTP-2002NP" thermal receipt printers randomly print out PJL commands. The printers are connected to POS computers that connect to a terminal server. The printer is not installed it is just connected to the com 2 port. The POS software runs from the terminal server and prints to the com 2 port. When this happens it causes the application to freeze up on the RD Web Windows Terminal Server for the individuals session. Does anyone know how LANDesk polls for printers to add them to inventory? Would LANDesk send the following commands to the com port during inventory to determine information?
