Printing problem with file

[Salman]

I want to print to a file and wants that it should be
appended when next print job is sent instead it deletes
the previous print

You can append data to a single "log" file using
Virtual Port Monitor. It can be a static filename, daily,
monthly, or annual log file renamed automatically.
