35. NG HINTS When using Print Master in a plotter sharing application it is recommended that you send plot files to the Print Master rather than plotting dynamically from within your plotting software You would typically have the application software direct the plot to a file and then copy the file to Print Master This method eliminates the requirement for full duplex communication between the computer and the plotter which allows multiple computers to copy plot files simultaneously The DOS command to copy the plot file to Print Master typically adheres to the following format COPY filename B COMy where y is the number of the appropriate com port and filename is the name of the plot file 32 It is still possible to plot dynamically through Print Master if required When plotting in this fashion you would probably need to increase the input inactivity timeout value to a higher number than factory default 20 seconds Plotting dynamically would not allow you to utilize the buffering capabilities of Print Master because the data stream from the computer is not continuous The dynamic method of plotting would allow only one user at a time access to the plotter due to the fact that the plotter can only respond back to the user who is currently connected through Print Master 6 3 LED INDICATORS All Print Master models have a green power LED and either six eight or ten red activity LEDs The green power LED will illuminate wheneve
