That works very nicely, but requires a PPD for each printer in order to
specify the filter and/or mime-type for that printer.  In my case, we
print text only to some OKI ML390 printers, for which none of the supplied
raster drivers work.  We don't care, since we only use the printers for
multi-part forms with text - so I copied the OKI 380 PPD, and modified the
cupsFilter.  The problem with this solution is that my PPD modifications
get wiped out whenever someone modified the printer with any of the admin

o Is there a minimal PPD that can be used for "raw" printers to specify
filtering for that printer without specifying a bunch of other stuff that
doesn't apply.

o How can I make a manually entered/modified PDP permanent - i.e.
protected from being overwritten by the admin utilities?
