hi @Jas as this question is related to specific topic use your favourite browser and keywords you are looking for are “prepare website for print”. You will find many articles that will walk you thru this process and reveal possible issues and how to solve them. There are also online services that may do it for your client based on URL. Or your client can just simply use any text editor as MS Word and export PDF of JPG and upload to his/her website as restaurants do.
