How To Print Directly to Printer

Expand Post »
Hi all,

How can we gain control of printer using php? I mean gain control as in, choosing the right printer from our php page and send the document directly to printer. I want to bypass the print dialog box that will appear when we print from web browser.

By the way, I've checked the PHP.net to check on printer functions (http://my.php.net/manual/en/ref.printer.php), it contains outdated links. I am really not sure how to get about using the function. I've already tried to download the php_printer.dll file from some website and unquote the extension in the php.ini file but can't get the printer_open() function to work, Perhaps someone can point to me where to download the right file or the right steps to do in order to use it .

I know we can't do this with Javascript, or can we?

Really appreciate all the info i can get. Thanks

Re: How To Print Directly to Printer

I don't believe this is possible as PHP is a scripting language, and therefore doesn't have the ability to gain control of hardware directly. For example, you wouldn't be very happy if you were surfing the web and various PHP-driven sites had direct access to your hard drive and hardware! What you're looking for should be possible through ActiveX controls. ActiveX controls are mini-programs (??) that are downloaded automatically over the Internet ... such as the way that the Windows Update website has control to install software to your hard drive automatically. Not sure how they work though ... that's a Microsoft thing.

Re: How To Print Directly to Printer

hi hi,

well, i think i;ll explain the scenario that i'm in. i'm doing a system whereby the client PC will request to print a list, and the list is of course sent to the server. On the server, it will analyze the list and dispatch the list to the correct orinter to print. Or maybe dispatching the list to several printers that I pre-set.

I want all of this to be done without the client PC having to select which printer to print to. Thus, I don't want the print dialog window to appear on the client PC.

Re: How To Print Directly to Printer

I'm not sure if there is a way to send files to the printer without the user's consent. That would be like hacking the enduser. The best you can do, from what I know so far, is that you can use Javascript to show the print dialog on a page (you can easily find the code for this online.)

Re: How To Print Directly to Printer

no,definitely not hacking. All I want is just this. The user on the client PC will click on a print button and the content of the page/form will be sent back to the server. The server will then dispatch the content to the appropriate printer. I just want to eliminate the step where the user needs to use the print dialog box. By the way, i need this for to do a web based application.

Re: How To Print Directly to Printer

I didn't suggest that you were hacking, but this SOUNDS like it. What I mean is that, since it seems like hacking, I don't think it can be done. But I'm sure you can do it in a similiar method.

Re: How To Print Directly to Printer

I guess the very first issue here is, PHP will be installed in your server. And there might be 2 issue, one is using WIN OS, and the other might be unix based os.
I know you can make use of LINUX command in PHP to trigger the printing. You can alos use normal DOS COMMANF in PHP if you are running WIN OS. It is simply the lineprint command or copy to lpt port. but I wouldn't know how can you track with the NETWORK Printer is ready, and able to print. Hope this does help. regarding the phpprinter command, it is only able to run in WINDOWS environment.
