Everytime I look back on this thread I see more layers added in and
things getting more complex. We're just making this app extremely
fragile and difficult to maintain.
So looking back at things. Correct me if I'm wrong. You have a Flex or
Air app which has to do a print operation (with no pop ups) to 1 or 2
prints depending on the item being printed. I'm assuming the printing is
centralize in the office and these print jobs aren't going off to
external (client side) printers.
Since the printers are centralize, then the server processing the print
job can also be centralize. Have a simple CF component using the cfprint
tag to direct print jobs to either of the printers. In the cfc you can
also build out the pdf to be printed. Then simply have your Flex or AIR
ping the CFC when it needs an item printed.

To do that, I'd have to move the code that builds the FlexPrintJob object to

it'll just have to be a part of the AIR app, then...
Or, if I were choose the serialization option -- I have no idea how I would
go about serializing a FlexPrintJob object... LOL Is it possible to save
an object to a file and pass the file's URL to the AIR app? Maybe that'd
work? How does one serialize an object, anyway?
Thought it was gonna be so easy -- just build the FlexPrintJob like I'm
doing it now, and pass it to the AIR app... But I guess it's not going to
be quite as easy as I first thought.

you can send some info. I'd expect the AIR app to except a couple bits of
info to build your FlexPrintObject. Another option, and wow we keep adding
layers to this, is to have the Flex app send the serialized FlexPrintObject
to the server, retrieve a GUID of sorts for it, pass this GUID to AIR, then
have AIR retrieve and de-serialize.

You can pass variables if the Flex app is a child of the Air app.

So I cannot send a FlexPrintObject over an L.C., is what you're saying?
Hmmmm... Is there a way to send a FlexPrintJob object directly from the
Flex app to the AIR app?

The local connention idea will only work if you can serialize your data
to a
string (XML). You cannot send serialized data over an lc. If you can do
that, then compose the XML and send it in chunks w an anknowledgemenr
each
time from the reciever sent over a 2nd lc. When you are out of data to
send,
the flex app calls a secondary fn that starts tearing down the 2 LCs.

The launching of the AIR app from the Flex app sounds like a better
idea,
actually... Then the Flex app has the control over the AIR app, which
is
what I want, it would seem...
I'm thinking the AIR app would be just a simple thing, taking the
FlexPrintJob object and a printer-name of some sort, and just sending
the
job straight to that printer...
So, once the AIR app is open, Flex wouldn't need to open it again,
obviously. It would seem that I would need to make a LocalConnection to
the
AIR app -- but documentation on that is pretty spotty, it seems. And
there
also seems to be a limit on the amount of data you can pass over a
LocalConnection -- 40KB, I think? How do I pass a large FlexPrintJob
through that, with that kind of limit on it?
Any ideas or suggestions?
Thanks,

Yet another possibility is to create a Air based app for the printing
and
have the Flex application open it, passing needed data to it for the
printing.
A example of opening launching a AIR app from Flex can be found here
http://www.medoix.com.au/2009/11/06/install-launch-air-application-from-flex-web-page/
Note there is a way to do this without the Adobe air.swf, but its no
documented :)

Another approach would be to create an AIR wrapper that encapsulates
your
print functionality. The AIR wrapper then loads the Flex app
(mx:Application). You simply put together what you want to have
printed
(FlexPrintJob) and then pass the instance up the parent chain. That
way you
can continue to maintain your Flex app as you are currently while
slowly
getting your feet wet in the AIR world w/o committing the entire
application
to AIR. (Additionally, you can continue to host the Flex portion
online for
update purposes; you just point the AIR "print client" at its URL.)

As (now) a desktop app. vs a web served swf:
If you want to do it by hand, you'll have to change the main file
from
<mx:Application> to<mx:WindowedApplication>; do a diff on the "."
files in
the project folder (compare to a generic Air app), 'cause there are a
few
changes.
If you want to add network sensitivity there is a bit more coding,
otherwise have your "not connected"/"fault" errors handled
appropriately.
That's about it! ... of course there is digital signing, update
awareness,
@etc;.

To clarify, I'm aware that FB4 has a "convert from Flash to AIR"
wizard... I don't trust wizards to actually do the right thing, in
most
cases... In fact, I generally find that they break more than they
fix...
So, I guess I'm asking for your experiences with this wizard, if you
have
any...
Thanks,

So... With all this discussion of printing from Flash Player and
whatnot, it seems almost certain that we're going to have to switch
to
AIR...
Has anyone here ever taken a fairly mature app from Flash Player to
AIR? I'm certain it can't be as simple as checking the "AIR App"
button in
the FB4 Project Properties window -- there must be something else
(or many
things) that I'm going to have to change/adjust/re-write... The app
currently interacts a great deal with our CF server, and I'd
imagine that's
going to have to change somehow, yes? User authentication would
probably
have to change as well, I would assume?
Can anyone offer any advice along these lines? If anyone here has
ever
done what I'm thinking about doing, please let me know about your
experiences.
