Hello.
thanks for your answer
First, my questions don’t concern the enbosser that couldn’t do what I need but
a potenttially new one, that would not have the same defalts.
- I f I understand well, an important question is the softwer taht takes let’s
say a pdf file and makes it something enbossable.
But, I suppose it’s not such n easy thing to programm this software.
Where could I get a service to concieve the transcription from signs to system
of points that I need ?
- where to find enbossers that can do differerent kinds of graphics ?
- apparently, enbossers don’t work weell with macs. is there a special
recommandation for this. I don’t specially need to operate through the Apple
computer but would like to know whether it is possible
- what does distinguish the enbossers ? why are they more or less expensive ?
Best

Hello,
I hope the following is helpful:
Nearly all braille codes are based on a matrix of 6 dots (there are some
which use 8, but for most languages on paper it's 6).
The various arrangements of the dots are then usually encoded as 63 different
ASCII characters. In the English-speaking world, it's called the North
American Braille Computer Code (NABCC) or USA Computer Code, or even "grade
0".
Thus, if I send my embosser an ASCII 33 (!), I expect it to produce dots
2346. (Note that dots 2346 is not the usual braille sign for an exclamation
mark).
The mapping between ASCII characters and braille dots is selected in the
embosser options. Make sure that your braille translation software and
embosser expect the same code.
If your embosser only knows that particular ASCII characters represent
particular braille dot combinations, then you can mix braille languages
easily in your document - all the embosser sess is a series of dot patterns
you want. In fact, you can equally well produce music braille and different
languages - it's all just based on six dots.
All the "intelligence" to establish the correct dot patterns is then usually
in braille translation software.
Layout is achieved by spaces and carriage return/line feed.

Several makes of embosser can also produce tactile graphics, mostly by
removing the small gaps which normally occur between ordinary braille
characters.
If you have an embosser capable of this, you typically send escape codes
(commands) to the embosser to put it in the graphics mode then send the
picture, then send further commands to return to text mode.
Some embossers have several different graphics settings, for example, to set
the distance between dots, or to state how the data is encoded etc.
All this, again, can usually be controlled by software.

To find out the capabilities of your particular embosser, may I suggest
consulting the manufacturer website, supplier or manual.
I trust this helps.
With best regards,
James.

Dear members,
Hello.
‘m Murtaza. I’m a phd candidate.
in fact, I nneed to know more about braille enbosers.
I mainly need to print generaly complicated texts with different languages
and sometimes strange notations.
my department in the university bought a braille printer but it could only
print page by page.
I think some enbosers can also reproduce picture, that could be quite
helpfull for me.
Best.

Hello,
Yes, we're receiving your messages.
Can you be a bit more specific about what you mean by a "printer", there are
thousands of ink printers on the market and dozens of braille embossers. They
vary in capability and price, depending on what you need to do.
With best regards,
James.
