print pdf page without opening

[rlu]

Is there a way to print a pdf document without opening it, if user just select the pdf files in the checkbox and click a button?

I tried the following two methods, but both fail.

1. open a new window:

[CODE=javascript]win=window.open ("","","widt h=5 height=5");
win.blur();
win.document.lo cation="http://www.mydomain.co m/mydoc.pdf";
win.print();
win.close();
[/CODE]
2. use iframe:
[CODE=javascript]iframe = document.create Element("IFRAME ");
iframe.setAttri bute("id","test iframe");
iframe.setAttri bute("name","te stiframe");
iframe.setAttri bute("src", "http://www.mydomain.co m/mydoc.pdf");
iframe.style.di splay = "none";
window.document .body.appendChi ld(iframe);

var x = document.getEle mentById("testi frame");
x.focus();
x.print();
[/CODE]

Did I miss anything? Or it is completely impossible to print pdf without opening it. Thanks a lot!

P.S. I found this forum is very helpful. It helps me solve many problems, so I posted this message first time here. Thanks for your answer in advance!

I don't know if what you're trying will be possible (never tried it myself), but what I can say is that you should wait for the iframe to enter the DOM before trying to access it. It's not available immediately, so you could use a setTimeout and check its existence before attempting to access and print it.

Mission impossible
The window.print() is not propagated (inherited) in your object pdf !!!!
The pdf objects has own print !!!
