I believe if you have BRMS you should be able to use that for it.
If you don’t have BRMS, you can copy your spooled files to a physical file, save/restore the physical file and use a small program to read and print the physical file to a spooled file. If you use the forms control characters, you can also get the line/page spacing correct. You should be able to find some examples of how to do this on the web. You may even be able to find some utilities for it.
Alternatively, if you have SNADS set up between the two systems, you should be able to do a SNDNETSPLF (this is option 1 on the WRKSPLF display panel). This should keep all the attributes of your spooled files.
