John,
I understand. That explains why my settings aren't being honored. Can you
enter the settings in inches or do you have to enter pixels? What is the
width of a standard Braille margin? I will try this out as soon as I get a
chance. Is it supposed to work now?
Best regards from Ohio, U.S.A.,
Vic

Here is a more detailed explanation of the discrepancy. It may be
instructive and even useful.
UTD is a graphical mode. It is based on a resolution of 20 dpi at
present, although the user may be able to specify the resolution in the
future. It also operates on full pages, so braillePages is set to yes .
Because it deals with pages, it requires that the paper width, paper
height and margins must be specified. If you look at a recent
preferences.cfg you will see these specifications. Braille is monospaced
horizontally. The wieth of a braille cell is 5 pixels. Horizontal
spacing varies according to whether the braille cells in a line have 6
or 8 dots. If a line contains only 6-dot cells the horizontal spacing is
8. If it contains even one 8-dot cell the horizontal spacing is 10.
When utd is specified the cellsperline and linesperpage settings are
ignored. and the paper size and margin information is used. You can get
the number of cells and lines you want by calculating the paper size and
margins.
The settings dialogue will eventually allow you to chose this
information, as will embosser setup.
