LISBON, June 26 /PRNewswire/ --

- European Research Firm Innovationstechnik Proves Original HP Inkjet
Cartridges Print More and are More Reliable Than Alternatives

HP today announced the findings of a third party report it commissioned
to look into the efficacy of Original HP ink cartridges as compared with
alternative, so-called 'store/refill brand' and 'refill station' European
offerings.

Leading European research firm Innovationstechnik tested more than 1,000
inkjet cartridges from 16 well-known European store/refill brands and refill
station offerings against their Original HP counterparts during late 2006 and
early 2007. The findings were very clear(1):

- Original HP inkjet cartridges print 34% more pages than compatible
alternatives(2)

- Original HP inkjet cartridges print 69% more pages than cartridges
refilled at refill stations(3)

As well as looking at the relative yields afforded by the different
inkjet cartridge alternatives, Innovationstechnik also tested their relative
reliability. The results were equally clear-cut:

- On average, more than one in five (24%) compatible alternatives were
dead on arrival(4) or failed prematurely(5)

- On average, one in three (33.6%) inkjet cartridges refilled at shops or
kiosks were dead on arrival or failed prematurely

"In yet another test, Original HP Supplies prove that they offer not only
better reliability and better quality results than alternative options, but
they give far superior value for money," said Vincent Vanderpoel, vice
president and general manager Supplies Business, Imaging and Printing Group,
Europe, Middle East and Africa. "Considering HP's unrivalled commitment to
environmental responsibility in printing supplies and choice of supplies to
suit every printing project requirement, the reasons to buy anything but
originals are becoming less and less convincing."

Innovationstechnik tested a minimum of 17 cartridges per cartridge type
and brand to ensure statistical validity, though in some case more cartridges
were tested as necessary to adhere to ISO/IEC 24711, which states that a
minimum of nine cartridges must be successfully tested. Page yield was then
calculated based on all cartridges tested, including defective units.

Similarly, the testing of a minimum of 17 cartridges tested per cartridge
type and brand ensured statistical validity for the reliability tests
performed by Innovationstechnik. Reliability problems were expressed as the
percentage sum of dead on arrival cartridges and those that resulted in
premature failures.

(1) Based on results of brands tested in 2006/2007 by Innovationstechnik
test commissioned by HP. Testing performed on HP 45, HP 78, HP 56 and HP 57
Inkjet Print Cartridges. Individual results may vary. See the
Innovationstechnik report at www.hp.com/cc/inktest for details.

(2) Confronted with different comparative advertisement rules within the
EMEA region, the percentage HP communicates across EMEA is based on German
comparative advertisement legal rules that bound HP to communicate the result
compared to the best German tested brand with 34.6%, instead of the average
test result of 79.5%

(3) Confronted with different comparative advertisement rules within the
EMEA region, the percentage HP communicates across EMEA is based on German
comparative advertisement legal rules that bound HP to communicate the result
compared to the best German tested brand with 69.1%

(4) 'Dead on arrival' cartridges were defined as those exhibiting
substantial ink leakage, fewer than 50 pages printed, or colour mix on 10
consecutive pages.

(5) 'Premature failure' cartridges were defined as those that afforded
less than 75% of the average yield excluding DOAs for that cartridge type and
brand.
