Are we saying that the green fringe that inshaala saw on prints that were
returned from Bonusprint were because the jpeg images were coded using
color space "Adobe RGB (1998)"  instead of sRGB -- even though there was **
no** *color information present in the jpeg files?????

Very probably !

For the mass production printers like Bonusprint you need to convert to sRGB their laser printers won't do it.  Only use aRGB for printers who specify they can use that profile.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
