After installation I got folowing error:
Error - mPDF requires mb_string functions. Ensure that PHP is compiled with php_mbstring.dll enabled.

PDF maker uses MPDF as PHP class to generate PDF files from HTML. MPDF requires the mb_string module to be enabled (see http://uk.php.net/manual/en/ref.mbstring.php) which means that PHP>=4.3.0 will be required as a minimum, and PHP 4.3.0 to 4.3.3 need --enable-mbstring=all. For Windows users: Enable the extension(s) in php.ini you want to use by uncommenting the extension=php_*.dll lines in php.ini. This is done by deleting the leading ; from the extension you want to load and restart Apache. http://php.net/manual/en/install.windows.extensions.php

System requirement

Please check your php variables. Our recommendation:
  • PHP up to 5.6 (we do not recommend PHP 7 because vtiger is not fully compatible with PHP 7 and you can have more issue with using)
  • max_input_vars 6000
  • max_execution_time 30000
  • memory_limit = 512M
  • post_max_size = 128M

    We use mPDF framework as HTML to PDF convertor. mPDF supports Truetype fonts, reading and embedding directly from the .ttf font files.
    How to easy add new fonts
    • Upload the Truetype font file to the fonts directory (/PDFMaker/mpdf/ttfonts)
    • Define the font file details in the configuration file (/PDFMaker/mpdf/config_fonts.php)
    • Access the font by specifying it in your HTML code as the CSS font-family
    • To use the font with specific languages, you need also to edit the configuration file (/PDFMaker/mpdf/config_cp.php)
    • Define the font type in the FCKEditor configuration file (fck_config.js)
