Here is what I did:
After checking all the usual issues in the Sharing and Print-Fax Control panels without any improvement, and verifying that local printing functioned normally, I went to the local machine, opened a browser window, and entered this URL:
This is the control interface for the CUPS printing subsystem on that machine. (CUPS stands for “Common UNIX Printing System” and appears be the mechanism that makes printing work on MacOS X.) Then I chose the Administration tab. This revealed a button “Edit Configuration File”. I clicked on that and got a editable window containing the configuration file. I located the following text sequence:
…
<Location />
Allow From None
Allow From @LOCAL
….
Interpretation: No printing request from a remote machine would be accepted. (Note: I neglected to write down the text I found there. I am fairly certain of the word “None” — it was either that or something synonymous.)
I changed this to
…
<Location />
Allow From All
Allow From @LOCAL
….
Yours might just have <Location /> with with Policy under it like this:
</Location>
<Policy default>
Enter it below </Location> and Above <Policy default>
and saved the edit. At that point I was informed of a printing subsystem reset.
