Why can't I get chooser to let me print on the Imagewriter?  There
must be something obvious that I'm missing but I don't know what.
Here are the details:

I just hooked up my home SE with a Grappler (connector which makes an
Epson-printer look like an Imagewriter to the Mac).  I have not been
able to make the Mac select Imagewriter for output.  Chooser gives me
a choice of Imagewriter and Laserwriter, when I click on Imagewriter,
then it asks me to select among printer and modem ports.  I click on
printer port, chooser does nothing, and I close chooser.  At this
point however, finder does not let me print: printing options such
as "print catalog" are grayed out, and set page layout (I forget
exactly what it is called) tells me that a printer file is missing.
In my system file I have a file called ImageWriter of type PRES
creator IWRT, and LaserWriter of type PRER type LWRT.  Are there some
other imagewriter files I'm missing?  I did have ImageSaver
(superglue) in earlier attempts, but moved that away because when I
would select Imagewriter under Chooser (as described above) the print
dialog boxes would still be for SuperImageSaver.  I have checked cable
connections: it is plugged into the printer port, etc.; Grappler seems
to be getting power (it gets warm), printer is turned on, etc.  
I have the usual collection of Suitcase, Popkeys, various inits like
Saratoga, etc.  The printer is a Diconix, which is an Epson-compatible
expecting 9-pin input (which Grappler produces).

Any help appreciated,
