html - Print embedded PDF from browser with Javascript, HTML5, AngularJS -

-

i'm loading base64 encoded pdf string javascript server. client application using angularjs, html5.

my html looks this: 

<div id="printablepdfcontainer">   <iframe id="printablepdf" width="100%" height="100%"></iframe> </div>

my javascript looks this:

var pdfname = 'data:application/pdf;base64,' + data[0].printimage; var embeddedpdf = document.getelementbyid('printablepdf'); embeddedpdf.setattribute('src', pdfname); $scope.printdocument(embeddedpdf);

my printdocument funtion looks this: 

$scope.printdocument = function() {       var test = document.getelementbyid('printablepdf');       if (typeof document.getelementbyid('printablepdf').print === 'undefined') {          settimeout(function(){$scope.printdocument();}, 1000);        } else {          var x = document.getelementbyid('printablepdf');         x.print();       }     };

the printdocument function has been taken pre-existing question in stack overflow (silent print embedded pdf) gives answer print embedded pdf. however, doesn't seem work anymore. i'm getting 'undefined' 

typeof document.getelementbyid('printablepdf').print === 'undefined'

check. seems .print doesn't exist or something.

so, questions this: how can print embedded pdf in html5, using javascript, , without opening popup window?

regards, phil

i'm going post learned here after lot of research in future might find this.

pdf's displayed differently based on browser, browser version, browser configuration, , operating system. there lot of variables i'll talk common situations here.

  • on browsers unable call sort of print() method through javascript, able use pdfactions. openaction call print. embedded these pdf using itext.

  • chrome uses adobe's viewer, doesn't give access sort of print() method execute pdfactions embedded in pdf. can embed 'openaction' in pdf , have pdf call print whenever it's opened application looks @ actions.

  • firefox (above version, recent versions though) uses adobe viewer in windows, recognizes pdfactions. however, in osx loses support adobe viewer , switches baked in firefox viewer (pdf.js). not support pdfactions.

  • ie: didn't test on ie. because gave on printing pdf's javascript after firefox didn't work on osx (a req. me).

my pdf's being generated server control ended making service changes in server , adding png service generated png based on same markup pdf generation uses. browsers handle images better pdfs, knew going in, hoped able re-use pdf generation service since it's used elsewhere in code.

it doesn't answer question, it's information have. suggestion might find in future: ditch pdf if possible in case , go simpler. otherwise, please update question if know how call print() through javascript in ff preview pdf viewer in osx.
