Open a printer emulation session.
From the Setup menu, choose View Settings.
This setting specifies the maximum size for a trace file, in megabytes. If the internal trace file exceeds this amount, the oldest data is overwritten by the newer data, a process called wrapping. A setting of 0 (default) means that the trace file does not wrap but continues to get bigger for as long as the tracing lasts.
Change this setting from the default value to trace problems that are intermittent or not easily reproducible.
