Cannot print Duplex pages from CS3, Need to Upgrade ID?

Question

I have been working with CS3 InDesign which meets my needs fine, until now, maybe...
I just purchased one of the new "all-in-one" Epson 635 Workforce Printers and was not able to bring up 'Duplex Printing' for two-sided printing, in the print dialog box where is should show up under output options. I'm using a newer MacBook Pro with Snow Leopard 10.6.7. I've also gone to the Epson site and updated the printer drivers for Snow Leopard.
In working with Epson technical support, we were able to get Word to print a duplex document from my computer, but when I go to InDesign, the print dialog does not contain the option for duplex printing.
Are there any solutions to this or is my only option to go for the expensive upgrade to CS5?
Thank You,
Ken

I'm not sure everyone reading this thread caught the subtlety: the spool time when you print from ID is in the foreground where you cannot work, whereas if you export to PDF that can happen in the background (for most of us), so it doesn't prevent work in ID.
Your PPD file does not demonstrate the "Xerox problem" I was referring to -- indeed, as you note it has:
*DefaultResolution: 600dpi
*ScreenFreq: "200"
So I draw a blank. My best guess is your problem is something else, or that InDesign isn't finding your PPD file. Since PPD files aren't [usually] the norm under Windows, well, I dunno.
As for the linescreen question, see the PPD Spec but yeah:
*ScreenAngle: “real”
*ScreenFreq: “real”
*DefaultScreenProc: spotOption
These keywords provide the default halftone screen angle, frequency, and
spot function, respectively. On Level 1 devices, these values are the angle,
frequency, and proc arguments returned by the currentscreen operator after powering
on the device. On Level 2 devices, only a type 1 halftone dictionary can
be easily represented by these keywords. Therefore, if the value of
*DefaultHalftoneType is 1, or if *DefaultHalftoneType is not present, these values are
the Frequency, Angle, and SpotFunction entries in the default Halftone dictionary.
If the value of *DefaultHalftoneType is anything other than 1, the values of
*ScreenAngle, *ScreenFreq, and *DefaultScreenProc may be meaningless and application
authors may not want to rely on them for anything important.
Note
To builders of PPD files: Although these are not required keywords,
*ScreenFreq, *ScreenAngle, and *DefaultScreenProc should be present even for
contone-only devices, because many applications have come to depend on
their presence, even though their values may be useless on a particular
device. You should assume that some applications will execute setscreen with
the values provided by *ScreenFreq, *ScreenAngle, and *DefaultScreenProc. To prepare
for this, if the value of *DefaultHalftoneType is anything other than 1, you
should put reasonable values for angle, frequency, and spotOption in the keywords
above. If you don’t know what values to use, try 45 for angle, 60 for
frequency, and Dot for spotOption, and make sure that *ScreenProc Dot is defined in
the PPD file.
I don't know if its completely ludicrous though. 1200dpi/220lpi is something I think of as normal, as is 300dpi/60lpi, your printer is 600dpi so 200dpi seems high but no more than 2x as high as what might be reasonable... "It's only off by a factor of two, the engineer said."
