If you print an address book card, you get a blank page. I guess that XUL doesn't

How do you print it?

we're trying to run a url, like:


that causes some assertions in the print engine code, as it first tries to 
figure of the message service for that url. 

then, we'll try to load it

rv = webNav->LoadURI(uri->get(), nsIWebNavigation::LOAD_FLAGS_NONE);

we never get back to the nsAddbookProtocolHandler.cpp, so we need to start 

but if we get working, the protocol handler does some scary stuff to turn that 
url into a card, and then turn the card into html.

I think we're going to have to revisit how we print address books cards, and 
entire address books.

not being able to print is pretty bad, let's say 0.9.9 to get it on the radar.

is bug 54527 a dup of this?

It can't find a protocol handler whose scheme is "addrbook" and here is the 
stack trace. We only cache "chrome", "resource", "file" and "http" handlers.

Didn't mean to commit the comment as I was debugging the problem. Please ignore 
the previous comment.
here's one place to start, nsAddbookProtocolHandler.cpp:

NS_ASSERTION(0, "fix me, FindPossibleAbName");

I noticed other issues, like how we use nsAbCardProperty and how we call
GetMessageServiceFromURI with the addressbook url when we are trying to print 

last time I looked, the way we printed addressbook card and how we contructed 
and ran the urls to do it looks very brain dead to me.  we should re-examine 
how to do this.

ok, I've made some progress on this.

at least, I've gotten it so that cards in the personal addressbook should print 
(but you'll get a few assertions).

I'll attach my patch, but there's still a lot of work to do to clean this code

start of the patch, still working on it.
those changes will be needed when printing an entire addressbook is supported, 
but I'm working on changing the way we print single cards.

here's how it works now:

from the selection in the results pane we get the nsIAbCard and we create a 
addbook url (which isn't even a valid URL or URI), like this:


when we run that url, we try to find a card in the "Personal Address Book" with
the email "".  if we find it, we get the fields out of it, generate 
some html, and then that's what gets read on the stream.  Some problems with 
that are what if you have more than one card with the same email?  also, there 
are bugs with determining the proper directory (see #54527)

here's what I've got working:

I've added to the nsIAbCard interface:

  wstring convertToHTML(in boolean aBase64Encode);

from the selected card, we call card.convertToHTML(true) and then the url we 
create is:

var url = "data:text/html;base64," + card.convertToHTML(true /* base64 encode 

the impl of ConvertToHTML() will generate (and base64 encode) the html for the 
card, for printing.

when we run that url, we don't have to look up anything, we won't be going 
through the addbook url handler at all, since mozilla can already handle data: 

for printing addressbooks, I'm going to rework it so we do this:


<foo> will be the same thing we currently use for our addressbook uri paths.

then, on the backend, in the addbook protocol handler, when I get one of these 
printall urls, I'll get the addressbook, enumerate all the nsIAbCards, 
call card.convertToHTML() for each of them, and put that on the stream.
moving back to 0.9.8, closing in on a fix.

implement card printing with data: urls

items left:

1)  generate all the html for the card (not just the primary email)


2)  clean up more of the addressbook backend code
3)  implement printing entire addressbooks
Attachment #63642 - Attachment is obsolete: true
cool, mozilla can print xml.

so instead of generating html, I'll generate xml, and provide a default .css 
file for the default styles to make the output look good.

then, we can restyle by modifying the output, or the user can style by 
modifying user.css

providing a way to generate xml for a card will be useful for when we add XML 
exporting of addressbooks.
blocked by #118613

printing data urls works, but only if the url is < 64 chars long.  rods is 
working on that.
