Music Printer Plus MP1 files
I have spent more than 10 years compiling more than 1500 lead sheets in the DOS program "Music Printer Plus". They are American standards and Jazz standards. This program supports transposition, printing, and file operations such as appending one file to another. Is there any way my mp1 files can be used by musescore?

See this handbook page https://musescore.org/en/handbook/3/file-formats which describes the file formats MuseScore can deal with. In particular look at the section on sharing with other music software. If you can get your music into one of those formats then Musescore can do something with it. But be prepared for some or much "retouching" two get the scores into an acceptable form. It depends how well matched are the assumptions made in the export and import processes and the type of information that is actually exported. For example, midi is very commonly available as an export option but midi contains little of the information needed to create notation, basically just pitch and duration as timed on and off events.
Good luck!

No, because the *.mp1 format dates back to 1982, nearly 30 years before MuseScore was released! The days of DOS, before the launch of Windows in 1985.
If you have the original installation of Music Printer still running, your best bet is to export each file in MIDI format. There is an interesting thread dating from 2013 about exactly this problem:
