Print html script from website

I would like to order a custom script that will give the ability to print and generate a pdf

Print and pdf of product card and blog article with all html formatting

Something like https://www.printfriendly.com/

However, there can be no links to external scripts in the code, it must be a completely original solution, tailored to our website

For the product, there must be at least the main photo, net and gross price, product code and product description

For the article, the title of the article and the whole content of the article including photos
