Where can I find the approximate cost of printing a page containing both
text and graphics on plain paper using 360dpi, coated paper using 360dpi,
and photo gloss paper using 720dpi.
I know this will vary considerably, but just a lead will help. I am using an
Epson Stylus Color 740 with compatible cartridges. Non Epsom.

You may have to search around a bit on the PC-pro site. They recently (last
months issue) evaluated some 13 or so modern printers across the major
ranges with pricing of page prints. They have always been thorough and quite
accurate: whether they've previously included your 740 I don't know - but
it's worth a search maybe. You may have to translate ££ to Ozzi trouser
buttons whatever you use :-)

Thanks Tony,
www.PC-pro.com is under construction at the moment.
Our poor little Ozzy $ works OK down here, but doesn't go very far in old
Blighty:-}

You could estimate the ink consumption using the formula in this page
http://yianni.hypermart.net/printer/inkjet/newtech/printcost/inkconsume.html
or this

For printing on coated or photo papers [using any resolution] use the given
formula. For plain papers use 1.1 coeficient. Calculation is derived from
accurate measurements on printing in plain paper. Printing on other type of
papes is an estimation. It don't include printhead cleaning ink consumption.
BTW, most of the measurements are done with an Epson 740.

I've extracted a few of the results that could give a guide:
The PC-Pro tests were for a typical text document with 5% coverage and
establishing the best quality proof for a 6 x 4 image.
Epson C84 - 983 text pages. Cost per page Mono 2.4p Colour 12.1 p
Epson 950 - 628 text pages. Cost per page Mono2.9p Colour 24.1 p
As it is a major contributor to costs they included the cost of the paper.
These were practical test carried out several times in that the printer
cartridge was run dry, or produced banding, and or ceased (refused) to print
any more.
The results from the Canon i560 and i865 produced noticeably low-cost mono
sheets at 1.5 p and 1.1 p respectively.
They do mention the "Dirty tricks", admitted by Canon and HP, Lexmark
apparently doesn't or like Canon declined to comment.
Underprinting is black text produced over a colour base to enhance
resolution and definition and can explain why many users protest they are
not using colour yet colour cartridges run down, just as much as the black.
I've plain forgotten which printer you're using now - but the figures could
be indicative.
One of our Ozzie users did mention that his JetTec c80 pigmented cartridges
were boiling over a bit - with 40 degrees C so an ice pack or fan may be
needed.
Or maybe you could drill a hole and we'll swap some climate - because it is
somewhat in the zero range here in the Black Mountains of Wales.

Thanks a lot Tony, this helps me greatly. I am being asked to print out a
few pictures for residents of our retirement village, and started out being
very generous and not asking for payment. That mistake cost me about
A$40.00.
Were the tests below done using Epson or JetTec ink?
Maybe we should live somewhere between Wales and Australia, however I cant
think of a happy medium that would be suitable.
With thanks,
Dave.

Hi Dave,
The PC-Pro tests were entirely with OEM Canon and Epson cartridges. We have
consistently maintained the JetTec at some 50% of OEM products. Not a lotta
people will know this but for instance the JetTec Canon BCI-6 is a different
design where the ink reservoir is enlarged and the sponge feeder smaller:
where the Canon refills with 6 ml the JetTec takes 11ml.
Currently a whole batch of the most popular Epson compatible JetTec now
includes the patented 30% more ink reset chip. The extended life covers from
the 680/777, C42, C62, 810/925, 1270/1290/900 and recently the C64/84 with
single cartridges and high capacity black using Lightfast and pigmented
inks.
Our tests are with JetTec paper but I've reproduced for instance the image
at www.inkylink.co.uk under "Paper matters" with JetTec and Canon/Epson
paper to match exactly the OEM inks. The JetTec C84 now includes an
optimised ink formula which enhances pigmented prints on glossy paper: the
bonus being increased colour gamut and longevity.
I've quite a few Australian customers including the one who boiled his
cartridges.
Solved your location between Wales and Oz-land: it's called New Zealand -
but they tell me its populated already :-) We have the son of a fairly
famous New
Zealander here in the village and he knew instantly what (Aotearoa) meant
in my logs.

The PC-Pro report listed the costs - including paper - of a 6x4 print as
best the Epson C84 at 28pence, R300 38 pence, Canon i865 52 pence, several
HP's at 69 pence, and (hold yer breath) the Lexmark P707 at 80 pence. Now if
half the OEM C84 price, life could be cheaper and more interesting. Bonus
print and Boots for instance come in at 15 to 18 pence for a 6 x 4 print.
The trouble I've found is that even if you're charitable the prints can fade
and complaints come back to roost: so pigmented could help your labours.
regards Tony
