Hi everyone,

I'm using a Arduino mega with a modified ethernet shield to send data to a printer (actually through a Jetdirect module)...

It's working quite fine except i didn't find the way to setup the printer an print in landscape instead of portrait.

Is anyone had an idea about it ?

Thanks

Interesting, can you post your code?

HP printers have escape codes to set attributes:  Landscape = 27 38 108 49 79 (decimal values

A complete (printer dependant) list can be found on: - http://www.dragon-it.co.uk/links/hp_pcl_codes.htm

All the code is based the pachatube tutorial and on someone's else work found on the net  but i didn't note whom and where... sorry for that

I just post here the code for printing something over 9100 port. My full  program is useless for people I think.



/!\ you need  PCL 5E compatible printer or something like that ( Meaning printer which use proprietary protocol should not work)

I have try different way with differents representation but my main problem is how to give parameters to printer.
The xxx.print() , xxx.println() and xxx.write() are just print like other text.

The printer didn't interpret the code, it just print it out.

Any clue for me ?

Maybe try this way....

Code:

    Serial.println("connecting...");
    client.print("\033&l10");    // [ESC] & l 1O to go to Landscape
    client.println("Hello Word");

I am actually used to controlling landscape/portrait via a job ticket that comes before the main print job.  This escape sequence is pretty old-school, but likely works.

Thanks for answering but unfortunately it doesn' t work. Anyway that the first time the printer don't print the code.

It prints : "ello Word"

with the write() or print()
println() just print "Hello Word" but still in portrait mode at least the printer seem to read something

I will try some other combinaison but other ideas are welcome

You might test printing the escape sequences byte per byte: 27 38 108 49 79 (decimal values

printLandscape()
{
  print((char)27);
  print((char)38);
  print((char)108);
  print((char)49);
  print((char)79);
}

followed by print("hello");

get the idea?

What exact printertype is it?
Its interpreter might slightly differ.. or just not support landscape;    URL manual?
