Real-world use of backend error handler?

[Michael]

Hi Brandon--thanks for the excellent answers in your post!  For some reason I didn't see your post before I wrote my previous follow-up post.  By the way:

In #1, I wasn't sure if the queue name was arbitrary, because the command line also specifies the old URI for the printer--so it could have been figuring out "which printer" that way.

In #2, a closer inspection of the man page verified that the -E flag does have 2 possible meanings--encrypt or enable--depending on where it appears.  Confusing.

Anyway, my printing is working reasonably well now (still have to fiddle more with align.ps at some point), so a big thanks to all the CUPS'ers out there.

Mike
