I assume all the commercial Print Shop disks are not too difficult to find. And long ago I also downloaded images of some very useful Atari 8-bit Print Shop disks which I had used in the 80s. Since I am located in the UK these were from the Page 6 Library (www.page6.org), which is still available as a fantastic web resource. (Thanks, Page6 maintainer, Paul Rixon I believe!). The disk images in question are listed in their XL/XE Library as The Print Shop Collection and Print Shop Collection Option Packs. They contain utilities and many graphics and can be found listed under "Printing". There are also several more Print Shop disks listed in the "Special Disks" section (DS85, 97,98,99...). It's likely you'll find Atari-related items in there.
I use Atari800MacX, which certainly can save Print Shop output to pdf and allows selection of the virtual printer from a list, which you can test with Print Shop's Setup Options process. Though I can't comment on Altirra it seems very likely it will do this as well.
I don't know about making an actual newsletter with Print Shop. Do the 8-bit versions have that option?
Anyway, have fun!
Jim
