How to print printer model on a PDF file when I print the file?
Anyone know the correct Javascript to obtain this result?
I don't think you can do this. Once the user has a PDF open on your site, it's a bit out of your hands: they have the PDF, and when they go to print it, the dialog box to choose a printer is provided by the system--not by your site, and maybe not even by the browser, really. I don't see how you can influence the content of the about-to-be-printed PDF between the time that the user chose to print it and the time that it actually is committed to paper.

I´m making a simple webapp, I want that when it is open in mobile phones print some data using the user´s wifi printer which most of cases will be an Epson L355.
Can anybody give me a clue or sample to achieve this?
Thank you all.
You won't be able to do this because you don't have access to the user's printer. Instead, you can just generate a pdf and redirect user on it.
The user will then be able to download / print the pdf via his inline PDF viewer.
You can do it by following this :
How to force files to open in browser instead of download (pdf)?
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.

I want to send a html text request to printer using PHP.
What I did was
window.print()
in JS, which is showing me a print dialog box, which is something I don't need. I
have used browser config:
firefox always_print_silent
I want to send the print command without changing the config on the client. I need a solution for any popup or dialog box and one that will work on any browser.
If anyone has a solution for this please reply.
If a web page could just send something to the printer without the user confirming it in some way, we'd have a wave of nasty spam and jokers that would print NSFW pictures until you run out of paper. I think we all agree that would be bad. So no, you cannot have a web page print without the browser showing a dialog box… unless the user knows what (s)he is doing and is explicitly disabling that like with the always_print_silent option.
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.

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.
