Thank you for the reference to <tex.stackexchange.com> which I was not aware of, particularly the tikz-??? part. I’ll see what the people on this list say before taking the problem there.

In my response to Herb, I’ve attached a file which includes a good part of my preamble and still causes the print errors that I mentioned.

If I understand your suggestion above, which I thank you for as I was not so aware, your solution is not what I prefer. I’d like to be able to use the TikZ code directly in the source code. There is a good chance that I’ve bungled somewhere. However, I must try out your suggestion in order to be able to compare file sizes of the TikZ code and compare that with the PDF's file size.
