But under printer permissions its set to allow "everyone" to print.

I don't know enough about Windows security to be much more help here, but I will say that if you're using IIS then the IUSR_machine user is 'special' and lacks a lot of the permissions that normal users have. Probably worth checking the result of printer_open - I'm guessing it's failing. You may also want to search the archives of this list as problems with printing come up fairly frequently. -Stut

Im having a few odd issues with printing and im hoping someone can help me. I can manually print to my barcode printer just fine (FILE<PRINT in a web browser). However if I try and print using PHP printer_write it doesn't print. Yes I have the php_printer.dll installed. My code: <? function getPrinter($SharedPrinterName) {

    global $REMOTE_ADDR;

    $host  =  getHostByAddr($REMOTE_ADDR);

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

} $handle = printer_open(getPrinter("ZebraZ4M")); printer_write($handle, "Text to print"); printer_close($handle); ?> Gives the following error: Warning: printer_write() [function.printer-write <http://localhost/test/function.printer-write> ]: couldn't allocate the printerjob [1804] in W:\www\test\print.php on line 19 And it doesn't print. I'm quite lost. Also, im using uniform server on windows XP and I do have my printer drivers install since I can print manually just fine...

It's almost certainly permissions-related. The user that your web server runs as needs to have access to the printer. -Stut
