Need some advice on Print'n'Play

I avoid print and play games because I don't have a printer, but so many games I want to play are only available as P'n'P. Of course I can just use a print shop, but I have a couple of questions about the process.

For roll n write games like the Waymark games I can just print on A4/5 and have it laminated and then replay all the time, easy enough.

But what about for card games like Iron Helm? Do people print on card and then just use scissors to cut them into the right shapes? I'm not sure how to print it to make it a nice, playable game rather than just scraps of paper?
