My architectural printer has roll paper over various width. If I want want to create a PDF, presumably, I need to create a custom page size of the desired roll width and a length large enough for the document to be printed.
However, in rhino the custom page size option is always grayed out.
In other applications, such a Word, I can create a custom page size in the Page Setup dialog and select in the Print dialog.
If you don’t have your MR50 license key handy or the page is giving you an error, you will need to contact our sales team (or perhaps @brian can help).
We discussed this before in THIS thread. It was (and still is) my belief that it had everything to do with the printer driver that you have installed. If it does not allow you to define custom paper sizes, that’s it I think, but maybe someone at McNeel can prove me wrong (I use 5.4.2.).
As I described, my printer driver will allow me to define a custom size, but will not print it, so I change to the pdf printer halfway through the process.
