Solve this problem (and I'll send you some money :)

I've asked around, I've placed posts, I've read everything I can find,
but I still can't get this problem solved myself.

Your turn.

$200 to the first person that can enable my Mac to print RAW Ascii data
to the USB port and have it drive my Prolific (PL-2305 chipset) USB to
Parallel adapter.

Must provide turn-key, repeatable, easy to use solution.
(either direct printing from an app or drag and drop to a printer queue
using a text file.)
Must not require plugging or unplugging of adaptor or any manual set-up
other than initial configuration. (plug n play, play, play)
It may be as simple as pointing me a raw printer driver online that
works or as difficult as programming a specific application just for
printing of text files raw.

I have already attempted all obvious paths including changing CUPS to
raw, terminal programs, various drivers.
I would also prefer not to use Gimpprint, but would consider it if a
turn-key setup was provided.
I am now using MS Notepad running on Bootcamp/XP and it works, but want
it to do it from the Mac side only.

But whatever solution is provided, it must work, be simple, reliable
and hopefully not break upon later OSX / CUPS releases and updates.

Mac is Intel Imac
OSX 10.5.2
Cups vers: 1.3.5

Data being sent is raw ASCII text representing HPGL code.
No Postscript, PCL coding or filtering allowed. Just 8 bit data.
If this sounds simple to you and you can explain it or provide an
installation package, you get paid $200.
I'm a serious person and easy to verify.
Payment will sent via cash, check or Paypal.

I don't own a Prolific USB/parallel but my Prolific USB/serial creates
an entry like "tty.PL2303-1B1" in /dev. Sending raw data to the serial
is as easy as a "cat yourfile > /dev/tty.PL2303-1B1" in Terminal.

I would guess that your converters driver has a very similar behaviour.
Plug in the USB/parallel adapter and do a "ls -ltr /dev". The right one
is probably among the last 10 or so. (Unplug and redo the "ls" to see
which entry it was ...)

Once you have the right entry in /dev it should not be to hard to write
an AppleScript to execute the shell command on drag & drop.

Sound like a formula that works during full moon only ...
