jetpipe is the upstream standard for printing.  Debian/Ubuntu developers 
confirmed that jetpipe can't do serial printing.  Both said they 
evaluated it for Debian or Ubuntu but they cannot ship it because the 
copyrights on the source files are unclear.  They were unable to contact 
the author to clarify the copyright thus both are unable to ship it. 
Fedora tends to have as-strict or stricter copyright/license compliance 
requirements than other distros so we likely cannot ship this either.

While lp_server cannot be shipped in Fedora directly, perhaps you could 
convince upstream to make a standard lts.conf option to allow using 3rd 
party print servers other than the standard jetpipe.

Otherwise, I personally cannot prioritize working on it.  Notes about 
your packages and how to use it should be added to the K12Linux wiki though.
