Hello Jean
Just had a quick look at Chapter 7 and do have one immediate suggestion – two main sections to separate the different printing methods and cover the extra pages/options available in macOS.
Using Heading 1 style, first section — Windows and Linux printing; second section — macOS printing.
Some of the printing information will be repeated between the two sections, but will help in preventing any confusion hn a user tries to print.
macOS printing does have several options available that do not appear in Windows or Linux.
What do you think? I can do all three operating systems, but will be at least a week before I can start.
Regards
