Setting PageMediaSize property of a printticker doesnt scale contents inside the page

[Legendary_Agent]

Hello, my current issue right now is when i send a file to a printer (lets assume its ISOA4) i want to scale it to A3 for example, when i use the pagemediasize = new pagemediasize(pagemediasizename.isoa3) indeeds sends to the printer to print it as A3 however it prints in that page as if its still A4 which means that the content inside it doesnt scale, ive been searching around the net and only found one article talking about a function which takes as parameter Visual class, i have no idea how to work with that or if even is what i am looking for, i simply want to scale an a4 page to a3, both paper and content written on the paper, as if it was amplified if you get what i mean, any info regarding this is appreciated as usual, thanks in advance!

EDIT: here is the only thing i actually find about it and its still a bit vague for someone who doesnt know if this is trully the only or the best way to print an a4 document to a3.
