Subject: RE: [flexcoders] Printing
directly to a printer
Hello Jester,
Not sure if I'm the one to explain it. Here's the website
where I downloaded it:
They have lots of controls to be used. In my application,
I have 2 web servers running, one server side and one local to the client, I
set it up on the client site and works great.
James
Could you elaborate on how this works? I
thought ASP, the code part anyway, ran server-side? Does it print
directly on the client?

I thank both you and Jester for your responses. As soon
as I read Jester's response, I went in search of an ASP solution and came up
with a module solution to the problem. They have a solution that will allow me
to print directly to a printer (in this case a receipt printer) . I have been
testing it and it seems it will do as I expect and the cost is under 50.00. It
comes with a quick install, that allowed me to get it up and running in 10
minutes.
Thanks again
James
James,
You touched on taboo subject
of Internet-enabled applications. Basically, printers and other
local resources like file system seem to be out of reach of developers - the
reason being that with complete silent control of the printer you are asking
for rogue page can send thousands of pornographic images throughout the
enterprise. So, in order to get the access to the resources like disk or
printer you need to be "trusted" - and over the years it was getting
harder and harder to get these credentials in Internet enabled
envitonments.
Second, you really need a
whole lot more then being able to bypass printing dialog for the application.
Honestly, aside from usability, I do not want user to select the paper size -
the application in most cases knows better (or can make better decision) if it
should use landscape or portrait mode/request paper size. Printers are quite
intelligent and can provide all the options to the application if they are
given a chance. Essentially, printer API should be far more extensive then
paper size (duplex, paper bin and paper type are few obvious ones) and
should have read/write access.
Flex positions itself in large
as front office development platform. As such business printing is
essential. I hope that Flash8.5 will address these issues under more
flexible security model. Other alternative of course would be to go along
PDF/FlashPaper solution - with well known interoperability benefits and
business application usability issues.
In meanwhile, you do not have
too many options. If you are deplying under IE you can get source code version
of our browser activeX (www.htmlprinting.com) as a starting
point to provide you with back door to the printing functionality while
maintaining complete security. After that you can "subclass" the creation of
PrintJob and expand the properties/methods via reasonable amount of C++ code.
That might be about 1 man/month project for proficient C++ programmer - assuming you can live with IE-only solution.
Breaking Mozilla to add printing, while possible, has not prove to be viable
for commercial products.
Hope this helps
Anatole

Subject: [flexcoders] Printing directly

Hello List!
One more problem for
you...Is there anybody out there that is currently
printing directly to a
printer?
Without the dialog boxes and previews, I mean straight to
the
printer...Example code would be appreciated, thoughts on the subject
are
welcomed...
James
