Bunny's daughter is an engineer who got a new laptop for work. She's having issues reading and creating PDFs for her job. She gets options for various paper sizes except the standard size used by architects. How can she create those? Leo says that may be a custom size that she'll need to purchase in order to use it. Leo advises trying other PDF software like Bluebeam and PrimoPDF. There's quite a few.
Another option is to pretend she has the printer she wants to print to by installing the printer drivers. Then just save it to a file.
