I am trying to get dompdf running on an in-house server. With the default config.inc.php settings, I get the following when running the equivalent of the demo \'Hello Wolrd\
We will use dompdf in codeigniter BUT the file that I’v downloaded from GitHub doesn’t has all the files that we need. Is missing all the files of php-font-lib. So we had to download it and uploaded to the respective folder. So, to have dompdf working in codeigniter you might have to download it.
