Printing in UN*X is possible too:



<?php

function lpr($STR,$PRN) {

  $prn=(isset($PRN) && strlen($PRN))?"$PRN":C_DEFAULTPRN ;

  $CMDLINE="lpr -P $prn ";

  $pipe=popen("$CMDLINE" , 'w' );

  if (!$pipe) {print "pipe failed."; return ""; }

  fputs($pipe,$STR);

  pclose($pipe);

} // lpr()

?>



You pipe the stream/string/char/sign whatever to the system. In the example shown above you have to add at least the string for printing in the function call. The second arg is a printer name which if you don't set will be set to the C_DEFAULTPRN. This is a constant definition from an ini file.



Hope this will help to save a lot of time ;-)

You can print in XP. AND, you can print to a shared printer with XP. The drivers for the printer MUST be installed on ther server as well as on the computer you wish to print with. Also, the printer must be shared on the client computer.



I am using a Zebra LP2844 Thermal Barcode Printer in my application. I am running XP Pro,Apache 1.3.27, PHP 4.3+.



Here is a function I use in our churches checkin system.  I use this to print directly to our printer with out having to use any Javascript.



First, i give the function the name of the shared printer. 



Second, I get the client computers host name. You could use just REMOTE_ADDR too I suppose.



Then I return a correctly formatted Windows path to the shared printer for the 



function getPrinter($SharedPrinterName) {

    global $REMOTE_ADDR;

    $host  =  getHostByAddr($REMOTE_ADDR);

    return "\\\\".$host."\\".$SharedPrinterName;

}



$handle  =  printer_open(getPrinter("Eltron"));



So, as long as you KNOW the computers are suppose to have a shared printer called "Eltron", you're all set to start sending info to the printer with the other Printer functions.

Please notice that what is printed is NOT measured in pixels, it is measured in pronter's dots.

Apply to fonts, coordinates and bit maps.

Should be pretty obvious, but in case there is any confusion...

The printer in question is one that is connected to the _server_, not the _client_.

I have noticed the for unix based systems you can also do this:



system("lp $filename")

[Editor's Note]


There is another free one available at 


[/Note]





As Bert said, a pdf generator wouldn't be bad. There is a free one at  , which can do the job. Inspite of the fact it is a little bit rough, it works fine and quite fast. It's just a matter of throwing the pdf file to ghostscript print it.

If you want to address the printer from your PHP-application in a Un*x environment:

This is possible if you use a different method.

In Unix it would not be logical to address your printer directly from php, but you could for instance generate a PDF-file with PDFlib (or a textfile, or a PNG/JPEG image with GD or what have you) and write it from your php-script to a directory that you use as a "printer-outbox."



Next, you write a shellscript that calls some unix tool to print all pdf or other documents in your "outbox" directory and then deletes all files in that directory.



Then you use crontab to run this script every minute or as often as you think it's neccessary.



You could of course also call the shellscript from your php-application with exec() but you'll probably want to avoid using exec() and the like for security reasons.

The X and Y co-ordinates are in dots.  



Get the printer resolution BEFORE printing anything and convert all co-orditantes to dots in the current resolution.  



Trying to change the resolution does NOT work in Win2000.



Anybody know where the source to php_printer.dll is kept?  I would like to fix some of the bugs that I have found.
