The idea was not to dictate from HTML how the printer should behave 
(number of copies, color, etc.). This should be up to the visitor, who 
can manage that in the print prompt. The request was about an 
alternative to javascript:print() where there would be no need for 
client-side scripting.
I probably gave this discussion a wrong turn by saying that a 
print-pseudo-protocol would perhaps be a good solution. I guess i should 
not have done so as my knowledge about such things is minimal.

I wasn't talking about an anchor, but about an id, which can be any kind 
of element, with any kind of content. This is how bookmarks work 
nowadays and it is quite similar to CSS id-selectors. As this "fragment 
printing" would be new I don't see any backwards compatibility issues.

It would be the same as it is now. Even with unobtrusive JavaScript I 
can not check whether a printer is installed and connected.
