Roy,

Here is a bit of additional information I've picked up from a very reliable colleague. 
Thought you might like to comment:

The deeper explanation going on here has to do with printing interfaces on OS X changing 
over time. In the past, some printer drivers (notably Canon, with its older iPF series 
printers) did not interpret the image data appropriately and thus had incorrect driver 
settings that could not be reset by the user. Photoshop CS3 worked around some of these 
issues for specific drivers, but did not conform to Apple's OS X specifications for how to 
pass image data to the print driver, leading to problems elsewhere. With CS4, Adobe has 
taken the approach of conforming to Apple's latest print driver interface specifications, so 
CS4 now has the same behavior as LR with regards to printing on OS X.

However, many print drivers have not been updated to conform to the OS X printing 
interface, and thus some folks are experiencing printing issues, such as double color-
management. This is unfortunate, but it really needs to be addressed by the printer 
drivers.

Now, back to the ABW situation: I don't know if Epson has a glitch with the ABW driver 
under the latest OS X release. I have occasionally seen what you've seen: i.e., I hit "Print" in 
PS CS4 and nothing comes out. But then I mess around a little with the Epson printer 
driver configuration and then it works.

In particular, I found that if I had an older "saved setting" or preset within the Epson driver 
that I used to recall a particular ABW driver setting, then it would fail. So I deleted all my 
Epson driver presets and started again from scratch (manually selecting media type, color 
mode, ABW settings, paper config, etc.) Then I haven't had any trouble printing ABW 
images since.
