Printing with an Index printer

[Sebastian Humenda]

Hello there,

I'd like to emboss (simple) braille with an Index printer. The current work flow
on the command line seems to be:
some_liblouis_command my_text.txt > mytext.brl
Adjust the line length:
cat mytext.brl |fmt -w 31 > mytext.brl

And then? I saw that there is a text2pef sub-command and a emboss command, but
I'm not quite sure how to use those.

Thanks
Sebastian

Hi,

Have you tried this:

Yeah, I overlooked it. What would be the device to enter on GNU/Linux for an
USB-connected index printer?

I've tried to convert a PEF file, using:
$ brailleutils text2pef brl.txt out.pef -doublex=true
Starting text to pef application...
Exception in thread "main" java.lang.IllegalArgumentException: Unknown option "doublex"
at org.daisy.braille.facade.PEFConverterFacade.parseTextFile(PEFConverterFacade.java:285)
at org.daisy.braille.ui.TextParser.main(TextParser.java:80)
at org.daisy.braille.ui.BasicUI.run(BasicUI.java:114)
at org.daisy.braille.ui.BasicUI.main(BasicUI.java:143)

What have I done wrong?
The text is attached to this e-mail.

Hi Sebastian,

You made a small typo, it's "duplex", not "doublex". Also, in this case, you need to specify the table, since the content matches two tables nabcc and de_de.

Assuming nabcc, the command on Windows is:
java -jar brailleUtils-ui.jar text2pef brl.txt out.pef -duplex=true -mode=nabcc

From what you wrote, I assume the command you want is:
$ brailleutils text2pef brl.txt out.pef -duplex=true -mode=nabcc

As for embossing, the command is simply:
$ brailleutils emboss out.pef

If this is not the first time you run this command you may need to use the following command first to reconfigure the embosser:
$ brailleutils emboss -setup

In the case of a USB-connected device, it might be more convenient to have a combined command. I have added an issue regarding this:
http://code.google.com/p/brailleutils/issues/detail?id=48

Note that, text2pef is designed for paginated text and the input you provided does not contain any form feeds which causes the resulting pef-file to contain a single page. Because the page is too high, it will not emboss. See also: http://code.google.com/p/brailleutils/issues/detail?id=39

Best,
Joel

I was too tired. I translated my text using libblouis, via the command
lou_translate (en-gb-g1.utb). Can I always assume that the output is nabcc?

Now I get:

$ brailleutils text2pef brl.txt out.pef -duplex=true

Starting text to pef application...

What is now wrong?

[Joel Håkansson]

Hi Sebastian,

I don't know. I have never seen it. It seems to me that either you are using an older version of Braille Utils (because I cannot reproduce it), or (more likely) that there is something wrong with the packaging or classpath. As far as I can tell, a resource file for the validation seems to be missing for some reason, and that is causing the error. Could you please try and download Braille Utils from Google code and run that as is, and tell me if you have the same problem? Also, if it still does not work, can you give me some details about the JVM and OS you are using?

Best,
Joel

So it still doesn't work which at least seems to give me the confidence that
I'll packaged it correctly :-). Here a screen dump:
===

Java is at version 6, but changing to version 7 yields the same error! I'm
running Debian Unstable, so presumably the same software as the current Ubuntu
has. What else details can I give you?

Hi,

Slight typo may cause the problem now:

java -jar brailleUtils-ui.jar text2pef ~/brl.txt out.pef -duplex

it should be:
java -jar brailleUtils-ui.jar text2pef ~/brl.txt out.pef -duplex=true

(also, I am not sure about ~/brl.txt, but that's just because I don't know much about Linux)

Best,
Joel

That should be ok, the shell automatically expands ~ in arguments to ${HOME}

I always forget that since that is not the common syntax :-).

>it should be:
Ok, then there is indeed something wrong with the classpath.

I have looked both into the jar's of your zip and my package and there is at
least the XSL file present. But I can remember that saxon was a bit touchy when
the class path was incorrect.
I also looked in the META-InF file of my version, please see the below attached
version. Is the class path incorrect? Should it have the full paths?

Sebastian
