I doubt that i will print out more than 30 pages per month, so cost per
page isn't a factor.
At least with lasers, this probally would not be an issue. But if we
are talking inkjets, the new canon line costs there and abouts of $78
to replace the entire set of cartridges, and it's not like you "can"
run them empty. I lack accurate data on how long a set of cartridges
lasts on the new canons for light users, but based on info from friends
one can expect to burn through a set of cartridges once or twice a
year, including color, even if you print no color. Now this isn't
trully horrid, but the fact remains that while you are shelling out
only $18ish for the black, and this information is correct, there is an
extra $60ish for no obvious benifit other than printing color once and
a while. This is why I would lean tward the HPs with the head on the
cartridge, worst case is you'll ignore the cartridge too long and seek
replacement for the $35 range, and actually get something for $35.
At least with lasers you can think in terms of cost per page no matter
how long the printer sits.
Now, also there is the capacity of the cartridge the pritner comes with
Brother HL-5240 for example costs $170, roughly $100 more than the
HL-2040, but claims to have a full cartridge. Whether that's the
TN-550 or the TN-580 i'm not sure, but if it claims to come with a full
one, and you are only printing 30 pages a month, you can buy the
printer, and not have to worry about toner for years. Further, you'd
shell out $70ish for the OEM toner rated at 3500 pages, which is about
what you'd expect to spend for the other models for more. This is
assuming the TN-550 toner. The TN-580 IIRC is double the capacity.
The hp 1020 from my understanding comes with a full cartridge as well.
