I'm a bit stumped by this and I'd really appreciate any help.
I've set up the breadboard and Arduino Ethernet as per the wiki and most elements seem to work. The amber light flashes intermittently, and when I send a test message, the amber and then green LEDs light up. When I press the button, the message prints out, but is garbled or elements are missing.
I've tried rewiring in the way that Daniel Dombrovsky managed to in a previous post, but that hasn't solved things as it did for him.
The printer itself is successfully printing the test page, so I don't think it's a problem with the printer.
As you can see from the photo, the successfully printed test page is upside down compared to my own garbled test message, which was supposed to read
...so I don't know if that has something to do with it?
I'd really appreciate any suggestions - many thanks!
