Is there any JS solution to download the PDF generated by window.print() ? I need not to open the print window, but simply download the PDF.
I have tried other plugins but the PDF generated by window.print() is the exact thing I needed.
Any ideas how to achieve the same?
i think window.print() function gives pop-up to print your html page..noting more, one alternative solution is you can use jsPDF library to generate pdf.

window.print() invokes the print dialog or printing process of the browser. Depending on the device, it either physically print a paper or write the output to a PDF printer.
Both these actions happen in the client side and the printout or the PDF is already with the client as of the end of printing.
There is nothing to be "downloaded" as a result of this.

And to select the PDF printer directly without seeing the print dialog, mostly a user action is needed. JS has no method to replace this user action.

There are some libraries which can turn your web page in to a PDF and let you download it. But none of them are as perfect as the browser default printing.
There are some server side solutions available. Those can generate the PDF with 99.9% perfection and send the result to the front end for you to downlaod.
Please see DOMPDF

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.
On click of a button, without doing a round trip to the server, can we save a HTML5 page on clients machine as PDF.
Check out PDF.js. This lib can create pdf in the browser (or serverside on node.js).
Using chrome you can print the page to a pdf file.
You need something like this, maybe server-side you can start a browser and print the content to a pdf file and send this to the client.
Disclaimer: i work for ByteScout
If you have simple HTML formatting and want to generate PDF on client side and if you have non-commercial project, check BytescoutPDF.js - it supports simple HTML formatting for text (font name, size, color) plus simple drawings and images, should be enough for simple reports
While using browsers like Chrome and Firefox, there is an option to print the page to PDF (that is saving the webpage as a PDF file).
Print this page
This code opens up the print page from where the user should manually choose print to PDF. Can this be done automatically? If so please help.
You can not print page to pdf with Javascript. You have to use server side script to print page to pdf. In PHP, you can use 3rd party PDF library like http://www.tcpdf.org .
There is not much available to print to PDF in Javascript.
The most supported option is indeed to generate it server-side using a library such as tcpdf (as shown by Thein Hla Maw).
I don't think Mark's solution is the correct one, since it requires the users to have some software installed.
For pure javascript PDF generation, there is this.
NB : thanks SO :-)
Yes... provided that your users have a few things installed.
They need a PDF print driver, such as PrimoPDF
If you want to automatically print to this driver, they need to have a plugin installed, such as JS Print Setup (for Firefox) or MeadCo ScriptX for IE
Then, using the API of said plugin, you can choose which driver to print to. You can even skip the print dialog.
A better option, however, would be the generate the PDF server-side, stream it to them, and then use JavaScript inside the PDF to automatically open the print dialog as soon as they view it. This way they don't need any plugins.
I have an app that generates PDFs and I want it to be able to print the PDF to the client default printer. How can I accomplish that?
Thanks
Edit: Javascript link could also work.
You could embed javascript in your pdf.
http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/Acro6JSGuide.pdf
So when you generate the PDF, use this.print() when the document is opened.
Rails only sends the PDF to the browser, and the browser/user handles printing. You really can't control what printer it gets sent to...
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.
