 PN directs printing to the line printer. See also PD, PF.
+Historically magnetic media had limited space.  So, in order to save disk space only the raw data was saved.  The more easily read "D" file was printed on paper.  To save paper, only diagnostics or measurements to ensure proper instrument function was printed.
+As magnetic storage became larger, space was no longer a concern and this command was no longer needed within the Canadian Brewer Spectrometer Network.
+The PN command has been omitted from the Canadian Brewer Spectrometer Network master program directory, as accidentally running this routine may cause the instrument to suspend measurements while waiting for a non-existing devise.
