When you cancel a print job in the Terminal window, PC Access temporarily ignores further print commands from your current host. PC Access has to do this because the host may continue to send additional print commands as part of the job you just stopped. After the host settles down, you can re-enable printing in the Terminal window. You should re-enable printing before you tell the host to print another report.
To re-enable printing, click the Enable button or Printing | Enable Printing menu item on the Terminal window.
