I am developing a web application which is displaying pdf files in web browser and i want to put restrictions on printing this document.Is there any way to stop printing to file as i need to print through physical printer only.
Since PDF can be downloaded to computer and than opened with any PDF reader, it means you can't prevent certain functionality of ALL readers.
You still can have your own interface that allows or disallows some functions, but I think printing to file is also browser stuff that can't be controlled using JS.
go through css3 media queries in MDN. You must find print media type in the page. It has some restrictions on page printing. https://developer.mozilla.org/en-US/docs/Web/CSS/#media or https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Getting_started/Media

My problem is the following:
I use PDF.js to display a .pdf on a website. However the .pdf must be included from some url. That means, that if one downloads the website for offline purposes, the .pdf will not be included and therefore can not be displayed. Thus I wonder, whether it is possible to embed the .pdf (e.g. in an html-container), so that it can be found by PDF.js. In this case, offline mode would be easy to achieve.
I think this can't be achieved without using a localhost (or a browser plugin etc.).
Is it possible to embed a piece of javascript in a .pdf doc, and have the script fire when the .pdf is opened in a browser? ... It should not require any user interaction inside the doc (like a click, etc) -- just fire the script when the .pdf is opened in a browser.
I would like to embed some analytics beacons or conversion tracking tags inside .pdfs, if this is possible.
Thanks in advance if you know any possible solutions! :)
Acrobat JavaScript has a method (launchURL()), which would send the message to the URL. You can run the according command in a Document-Level JavaScript (which is embedded in the document, and gets executed when the document opens). More to this method and its implication can be found in the Acrobat JavaScript documentation, which is part of the Acrobat SDK documentation, and downloadable from the developer section of the Adobe website.
However, it requires that the PDF viewing component of the webbrowser supports Acrobat JavaScript. And that limits you pretty much to Acrobat (Reader) using a browser which still supports the Acrobat Browser Plug-in, and the Acrobat Browser Plug-in has to be active. The PDF viewing components built into the browsers are too dumb, and your code will not get executed.
On the plus side, this approach also works when the document is opened outside of a browser; sole condition is that the PDF viewer does support Acrobat JavaScript, and the launchURL() method.
Aside the interesting Acrobat answer of Max, AFAIK it isn't possible to run JavaScript in a PDF without user interaction.
To track these interactions with PDFs in the past, we have instead relied on event clicks on the PDF view link instead.
However, these days consider server side tracking by sending a Measurement Protocol hit when the PDF resource is viewed, ideally taking the same cid from a cookie in the same session.
Good day,
I have a system that renders large amount of data through pdf ( 30mb + ). Now I want the user to view pdf first so he can either download it or just print it right away. as of the moment I am forcing the user to download the file since open( 'datauri here' ) wont work with larger files.. the problem with downloading is that files are multiplying and consumes space over time and also its not necessary for me to download all files that that they want to print right away.
I need a functionality that is similar to chrome's preview when using windows.print
can you please suggest any ideas or other things to do this?
I am currently using javascript library to create pdf (pdfmake). I am also using chrome as my main browser
You would have to make sure that the PDF is optimized for fast web view, and that your server is using the byteserving protocol for serving the file.
If that is the case, a useful PDF viewer (such as the web browser component provided by Acrobat/Reader) understands this protocol and requests (after the first page plus overhead of the PDF) only the data for the pages which are to be displayed.
A quick search did, however, not reveal whether the Chrome PDF viewing component is smart enough to understand the byteserving protocol.
I have web application that dynamically generates XHTML. The XHTML is then converted to PDF using Flying Saucer. The document is then streamed to the browser and served inline.
Part of the requirement is to automatically print the generated PDF without user intervention and then closing it. I have never come across such a feature before. Can I print the PDF from a web page using JavaScript? considering I don't have a physical file location!!
Any thoughts on how to tackle this issue would be appreciated
I need to set up a print button in HTML that will print a certain PDF file, hopefully without having to download the file first. I've tried a few things but some only work in IE. and some require downloading the file as an embedded object which also is not acceptable. Embedding javascript in the PDF sounds the most promising, but I'd rather avoid that if possible for other reasons.
Any other ideas?
Unfortunately it really can't be done... PDFs are not handled naively by any browser, and as is such they can't be printed using the browser's print dialog.
Your users will have to download the pdf and print it with whatever PDF software they use (Even if it's just a plugin for the browser) unless you convert it to boring old html or an image or something.
You cannot print something without the user downloading it first.
The printer is located on the user end of the connection. The PDF is, at first, located on the server end.
The PDF must thus travel across the webs to reach the user end before the printer will know which ink to put on paper. In other words, it must be downloaded.
I think the best you can do is download the PDF into an iframe element, and advise the user to click the "print" button in there. To my knowledge, no tighter integration than that is possible. The PDF viewer's print button can not be accessed via JavaScript.
