An error free dot code image? You mean something like
http://users.skynet.be/firefly/gba/e-reader/slp100.bmp :)

Btw, I printed it on a label using my Seiko SLP-100 thermal label printer
(203 DPI) but, as suspected, the e-Reader did not recognise/see it. Will try
on my Epson 460 Inkjet printer once I have refilled the ink (messy job with
a needle & stuff). At times like these I wish I had bought the Dymo label
printer (300 DPI) instead.

Pretty much. The dots should have some white space between them. Also, can you provide me that same image, but in 1200 DPI, length = 7.3cm, width = 0.3cm?...
