How to make print card work in Linux: solved

[Peter Alcibiades]

This is what you do and do not do.

First, you do not test this from the IDE in run mode.  Because if you do, 
you'll discover that changes to the script have different effects when the 
app is launched from a startup stack or, probably, when compiled, from 
those it has when run from the IDE.

Nor do you test it on anything but the identical configuration of the 
machine that will do the printing in real life.

My problem all along has been to think that identical settings in the print 
parameters would lead to identical results on different machines.  They do 
not.  Also to think that identical results would be obtained from the IDE 
in run mode and from a launcher stack.  They are not.  This leads to all 
kinds of grief, as when you finally get a setting that works in the IDE on 
machine A, then move to machine B and run the app, and discover that it 
does something totally different.

Instead what you do is start from whatever startup stack you are using to 
launch, or start up the compiled app.  Then do the print.  Make a note of 
the settings. Then close the stack, open it in the IDE, modify the 
settings, recompile if need be, close down Rev, start up from the startup 
stack or the compiled app, print again, make a note of the settings.

This must be done on the actual computer and the actual display from which 
the print command will be run.

Iterate, changing one parameter at a time, until it comes out more or less 
right.  This took me the better part of a morning.
