Error using mike42/escpos-php library

[malihaz]

Im working on PHP based web application for booking. The guest room owner wants to use Black Copper BC-90AC thermal printer, which is USB printer for guest receipt. So I want to use mike42/escpos-php for the purpose. I have included the library into my project using composer, however when I run a test page, I get following error.

Warning: require(E:\XAMPP\htdocs\test\vendor\mike42\escpos-php\example/vendor/autoload.php): failed to open stream: No such file or directory in E:\XAMPP\htdocs\test\vendor\mike42\escpos-php\example\demo.php on line 11

Fatal error: require(): Failed opening required 'E:\XAMPP\htdocs\test\vendor\mike42\escpos-php\example/vendor/autoload.php' (include_path='E:\XAMPP\php\PEAR') in E:\XAMPP\htdocs\test\vendor\mike42\escpos-php\example\demo.php on line 11

Any suggestions would be appreciated.

What you're missing is running composer install, which will import your packages and create the vendor folder, along with the autoload script.
