i use priprinter (fineprint pdf is also usable) and print and print and PP gather it all to save in one pdf.

it depends on forum software if it offers all answers on onepage or printable view. MZ only has print view and only for one page.

some forums have options for shown answers per page.

I've had bad luck trying to use "file -> save file as" etc. to do that. I suggest you print it using a "print to pdf" print queue rather than to a actual printer. That feature is offered in windows 10. If you install the [url=https://www.gonitro.com/pdf-reader]free verison of Nitro's pdf reader[/url] it will create a similar print queue. You should be able to find similar freeware if you don't like it. I've never run into a page limit using print to pdf, though I assume one exists if you run out of resources due to using a ridiculously high page count.

Extremely useful forum discussions sometimes range over multiple pages.

1. Is there any way to save these threads in a single operation, rather than save one page at a time?
2. What limit on number of pages saved is there?
