The Specific example this was found for was an XL206CLFP with switch 80-0. Press five had a Press Reaction time and no other presses did. If the P option was not present, the parameter would not be present.

This was tracked down to some code that was trying to ensure the Printer Press would have a reaction time. However, it was implemented incorrectly.

The logic was corrected and simplified, which rectified the issue.
