That's spot-on, but do not think I am wedded to this technique. If I had
a desperate to print a one-off (like the originator of this sub-thread)
I would use it but would be cogniscent of its limitations. Manipulating
images within the printing system is fraught as far as I am concerned.

A twist with the page he refers to is that getting the whole page with a

CUPS itself has removed or deprecated such options:
It is cups-filters which carries the flag now.

An ordinary user shouldn't have to do this. OTOH, an ordinary user
should not feel it is acceptable to impute motives and spread false
information. A skilled user (such as the starter of this sub-thread)
could have copied and pasted or used 'lynx -dump ....." to get what
It's a pain, But needs must on occasion.
