I can't think of any publishers that are also in the business of printing and distribution. Those are entirely separate industries. There is almost no way for publishers to lose money because of tech that makes it cheaper and easier than ever to get books to consumers while retaining unprecedented control over pricing (fixed, never discounted or remaindered), resale (prohibited), and lending (also prohibited). Publishers sell eBooks for the same price as print books but pay almost nothing to produce them. That's a big bump in profits.
I don't see how any publisher is losing money on their back catalog due to scanning by Google, either. Google doesn't sell or even offer access to the full text of most books they scan, certainly not any that are under copyright and still being sold by publishers. Out of print books are by definition not earning money for publishers, so it wouldn't make any difference there.
Notwithstanding what I understand about the publishing industry, I'm talking about the marginal cost of distributing a .mobi or whatever versus manufacturing a printed book, not the entire cost of publishing an eBook.
That's only a dollar or two of difference per unit in costs to the publisher. The majority of their costs are exactly the same for ebooks and printed books.

You're right that publishers don't handle printing, but they do need to handle distribution. Amazon won't help if you want to get books on shelves of retailers, and printers don't distribute. Smaller publishers will usually use the distribution network of a larger publisher. For example, HarperCollins and PRH both handle distribution in the UK for themselves and others.
