Hi Rich,
What I thought I was trying to do was read the doco for various applications; and especially for cups; as man is the standard application for doing this (in the UNIX world anyway).
This is the biggest problem I am having coming to grips with tiny core linux, the apparent lack of documentation. I followed the instructions for cups as listed in appbrowser ( a separate discussion thread) but have since been told that is incorrect. So I need to read the doco on cups to work out what I do need to do to get it working.
I use the term "apparent" because I assume it must exist somewhere. Where, and how to get at it, seems to be the hands of "secret squirrel).
