This will work just find you need to configure the embosser to use serial as opposed to Parallel. you will also need a serial cable with male 25 pin on the embosser end and female 9 pin on the other. this is a fairly standard cable used all the time to connect things like external modems and such you might also need a null modem adapter which will go at the 25 pin cable end.


Louis has setting for number of cells on a line and number of line to the page. There may be similar setting in the embosser's firmware as well.

Hello,
I hope we understand each other well.
I mean, my braille printer is a parallel printer , at the moment connected
on my parallel port of me linux pc /dev/lpt0.



Anyway, I have a usb-to-serial convertor myself.
but, I think, this shouldn't work because:
1 side of the cable has a usb-connection to put in my pc, this is ok.
The other part of the cable has 25 dots.

So, my printercable has also 25 dots to put in the pc, so this doesn't
work I think.
Is this not what you mean with a serial convertor?

But, when the printer is properly connected, I should need a driver, a
way to format my papersize, a way to chose the brailletranslator.....

Or perhaps, the settings of the embosser will be used?

It is needed to connect a Mac to a serial device. Your index Everest
should work fine as it has a serial interface. You will need a null-
modem cable or adapter and perhaps various kinds of gender changer
adapters depending on the connections on the embosser and the cables.

I have quite a bit of background embossing braille on a Mac. I am the

You will want an embosser with a serial port as well as a USB to
serial
adapter, I suggest the Keyspan adapter. It may also be possible to
use a
Parallel to Bluetooth adapter but I have not personally tried it. At
this
point Louis does not support USB embossers.

Louis will translate text, Word, xml, html and a wide range of
documents. It supports many different braille codes in many
languages.
You can write you own translation tables for Louis if you wish.

Hello again,

Is here someone who hava experiences with printing in braile on a
mac?
I don't know if it's possible but perhaps, it should be possible
with
some types of braille printers.
I can have a new one so, if I take the right one, this will be nice.

and also about braille tables:
I asked here before but is het somebody who knows about other
brailletables then the Us-table?
Normally I use the dutch one.
Is this kind of brailletable also available or can I adapt the us-
table?

thanx in advance
best regards,
