This is very easy way for generating pdf reports from html files using PHP language, I have used it in my project as well which was quite helpful when we wanted some specific layout or format like table data etc., The only thing that i don't really enjoy about this service so far has been its pricing structure where there are certain limits if you use more than 10 users per month then your price increases but nothing majorly bad yet still not too much dislike either! So yes definitely go ahead & try out their services once at least they will be good enought choice since most other companies charge higher prices compared even free offerings by others!! We were solving our problem regarding generation multiple Pdf report within one page without having separate pages/files needed just single file generated all those different formats together.
