IANAL...
But, given prior allowances and , Making copies for table use? Marc probably will consider that fair use..
Making copies for them to keep? not likely.
Printout of a whole book for at the table? Yes.
Printout for sending home with a player? only for temporary use.
Some history
Now, there was a period where Marc explicitly allowed copying books for friends... Only CT materials by GDW, and only one such copy per physical book. That has been withdrawn, since Marc started selling the big floppy books, and Hunter was securing a license to CT to sell the PDFs. (One of the early era of COTI funding streams was a license to sell CT PDFs. Only with the recent change of board has the last vestiges of that store gone away. Hunter also was licensed for the various Pacesetter RPGs, but those now are licensed to PIGames.
One of the risks of ebook purchases: when the storefront loses the license, or the storefront goes down, people lose access to their materials.
I'll note as well - the CD and DTRPG scans are so very much better than the ones Hunter put up... but they're on a new generation of both hardware and OCR software.
Marc has always supported reasonable use for play as fair use, provided that it's at-the-table use.
