the printer functions like printer_open() etc are not working in my windows 7 . I use php 5.0 and it says call to undefined function. can anyone help me on how to print receipt or first of all sending print jobs to printer.
It the undefined function error message means the printer extensions are not installed.
The docs contains instructions for installation:
php_printer.dll is not supported anymore in PHP > 5.3.x. so make sure you have PHP 5.3.x, not 5.4.x and go here to download the associated dll http://likepie.net/2012/php_printer-dll-and-php-5-3-9/
