well.... not really...

Well... the E3 seems to be used in most of the newer Primax scanners... combined
with different CCDs with different resolutions...

right... but from reverse engeneering and tracing the parallel port we cannot really
find the border between low-level and high-level...

Well... we signed an NDA... got some bad docs and some scanners and were
left alone from then on again...

Well... it really works! And that really good... but only for the Primax Colorado Direct D300
and compatibles... not for scanners with the E1/E3 Chipset...
We're going to bring it to Beta-Test next weeks and release 1.0 then...

asking questions doesn't cost anything... only when tey're FAQs... so please read them before
asking anything...
