How to send the string data for printing to the printer or virtual printer ?During testing ,instrument is connected to the printer by GPIB card or port 232 ,after pressed "print" on the panel of instrument ,it sends the string data to the printer.can the process been simulated in labview?
I'm not sure if you really mean automated instead of simulated. If you want to issue the print command from LabVIEW instead of manually doing it, you need to read the instrument manual to see if such a command exists. If it does, do a VISA Write of the command.
You might also want to watch where you post. This question has nothing to do with NI switches.
