What operating system and web client are you using? I did something like
this a few months ago. Opened the content in a separate hidden window
then used javacript "window.Print" then closed the window after it was
done. It's not completely reliable. If I remember correctly, it worked
with some versions of IE (circumventing the printer dialog box), but not
Firefox or Opera browser.
I think what we ended up doing was (and this is on a windows system),
creating a unique mime type and configuring windows and the browser to
run a batch file. When that mime type was detected, a batch file was
run which copied the downloaded file to lpt1. Essentially dumping the
contents to the printer. You could probably use the DOS commant line
"print /d:LPT1: c:\temp\temporary file" to do the same.
This will work if you are dumping something like raw data to a label
printer.
Other odd situations arose also. On some machines, the default mime type
stuck after the initial selection and we were not able to change it
back. It's been a while so I don't remember all the problems, but at
least you have a general idea in which direction to travel now.
Good luck,
Rolan

Ok so i misunderstood the actual requirement.
THe page would have to print on the client machine as there are
many machines running the scan guns. I am assuming i would need
Javascript for this task but i am not sure if there are any
libraries out there for this already.
We would want to print the page to the default printer completely
bypassing the print dialog that pops up.
Any assistance will be appreciated.
Thanks,

Ok Guys & Gals,
I know i have seen talk on this subject before (or similar)
but i never had a use for it until now.
My fulltime employer has their warehouse application written
in PHP controlled with scan guns, etc.
When they pack an order they scan the barcodes and it
processes the order. The script then generates a PDF and
currently redirects to the PDF so that it will
open in the browser. They can then hit print to print the page.
We would like to streamline this a bit more. Rather than
redirect to the PDF we would like the PHP script actually send
the PDF directly to the printer. I know you can
do this as i recall someone doing it with a DYNAMO labeler.
The question is where can i read up on this topic. We would
need to send this off to the default printer port.
Any insight would be a great help.
Thanks,
