The code that Jim put above is very similar to the line in the code
I sent.

My 'graybar' code was written after reading Jim's two columns in
The Guru 12+ years ago.

It's been awhile since I've used those examples and I don't have a
PCL5 type printer but the first long one is the old graybar
standard with 3 shaded lines followed by 3 clean lines.  I think
one of the the others just alternates the bars.  I do recall using
pieces of the code to do shading only where needed, such as an
invoice with only the data lines being gray-bared.

That code was all under FP 4.0 or 4.1 so it may be easier to
implement today.
