I just downloaded the latest version, and from Summary tab I choose the print option.
After a while my super-fast printer printed more or less 50 sheets of data (mainly windows defender definition and malware removal tool updates). IMHO an option to print ONLY summary is required.
Yes, you found the only one who printed something :D
This would be more commonly intended for use with Print to PDF or similar, I believe, which is why there isn't a Summary option. I'll be happy to let our development team know about your interest in this functionality.
In the mean time, I believe you could use Save to Text File, remove the unneeded section(s) from the text file, and then print that, as a bit of a workaround for this.
