You'd have to print out your own, you can't actually buy a hard copy of any recent ISO C++. Some national standards bodies, entitled to do so, might claim they can sell you one when actually they've got a deal with a relatively local print-on-demand company, but because this standard is huge that company will reject the order so you in fact can't buy the product you'll get an apology, or a PDF or both despite specifically buying paper. Although their processes are hopelessly antiquated (fly to Hawaii to fix a typo? I don't think so), the result is, as you might expect in 2023 - just a bunch of document layout source, from which "draft" versions of the document are publicly available. Not as useful if you're getting burgled, or to raise a display off the desk, but more practical for real work.
