On the 2nd of October of 2013, we were after a certain cartridge for a certain printer
for the second time. The printer is called HPDESKJET 930c but the cartridges
that we should buy for it are HP 45 and HP 78 (black and other colors).
The questions that occurred to us, as we went through all the
other brands of cartridges, were:
1) Why do they not have an Epson 45 cartridge? Is it
possible that they do?
2) This 45 has to do with shape? Why so many shapes?
3) Why do they have to have one cartridge for color and
another for black? That makes it all be so expensive!
These cartridges should cost at most AU$ 20 each, not
mattering whether they are black or color. If there were competition, as with
all other items of consumption, and Epson also produced a 45
cartridge, then we would be paying what they deserve, that is, at most AU$ 20
per item, so that we should have competition in that area.
We asked the seller that and they answered: You have to buy the number that they say is the number for your printer
and only that number will be suitable. We only have one brand for that number,
which is the brand of your printer.
Looking for information on the Internet helped with
nothing, since the websites look as if they have been written by people on
high heights: We were wondering about the numbers, the title refers to
the numbers, yet their writing refers to at most the letters!
In a rational world, the number would mean shape and
dimensions, like each different number would give us a different geometric
shape for the cartridge and a geometric shape that has precisely certain
dimensions. In a rational world, all ink cartridges manufacturers would sell
all numbers, so that we would have the so healthy (for the consumers)
competition. In a rational world, the government would not let the printer
manufacturer change the shape of the cartridge without presenting a scientific
reason to do that, since that would imply problems for the consumers in terms
of supply and the appearance of what could be seen as illicit profit for the
manufacturers.
Epson has got an Epson Stylus c45 (https://www.epson.com.au/products/inkjet/c45.asp).
The cartridge used with this one is called T038 (https://www.epson.com.au/products/inkjet/c45_specs.asp)
however and is very different from the HP 45 in shape.
HP has got an R45 (http://www.hottoner.com.au/HP-Officejet-R45-Ink-Cartridges-c7474.html).
Interesting that, according to the same website, we could be using the HP 45
with this one.
Canon has got a Canon mp45 according to the website http://www.fixya.com/support/t2374764-canon_mp45_printer_refuses_print_using. However, the website of the company seems to tell us that such a model doesn't exist (http://www.canon.com.au/).
Oh, well, all in all, we should fight for our rights also in
this area.
