View instructions. If it is a brand-name computer, it will usually come with a computer manual or a detailed hardware configuration list, from which the memory model can be determined. Check the actual memory.

Steps to check the generations of notebook memory modules: Check the manual. If it is a brand-name computer, it will usually come with a computer manual or a detailed hardware configuration list, from which the memory model can be determined. Check the actual memory.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements.
