The 23Sep90 version of modes.mfj (the current one, I believe) says:
 
def lj=[mode=hplaser[300]; output=pk[c:\newfonts\pixel.lj\%rdpi]; tfmlog];
 
Remember that, once upon a time, emTeX *did* use .pxl files.

The problem with using % in a batch file is that COMMAND.COM uses it as
a metacharacter.

No.  The whole point of running METAFONT is to create the .tfm *and* the
.gf files.  The input needed for METAFONT is generally a .mf file.

They shouldn't be machine dependent, but unix and/or vms and/or etc.
transfers have been known to mess files up.  The easiest way to see
if it'll work is to do it and see what happens.

All the bigger archives should have the parameterized version of CM
files, allowing you to make up fonts in arbitrary sizes (within reason).
