Re the 8250. It is a nice printer and many other HPs use the same 02 ink tanks. I think it went for $150. or more originally. The HPs are quite different from most other 6-tank printers as the tanks are stationary and connected to the head with a tubing harness - making for a much lighter moving assembly so they don't need as strong a carriage motor as they would otherwise. This also means that it's duck soup to implement a continuous-flow ink system to large bottles of ink for those that need that sort of thing. But it still has the drawbacks mentioned earlier. I don't think the 8250 comes with the underfilled tanks, but beware, the flunkies at the big box stores tend to lie about that to get you to buy a new set of tanks right away. They must get a good spiff for upselling OEM carts... It's usually only the low end that get the Starter cart treatment: inkjets that normally sell for under $100. and lasers under $200.
No, the USB cable you linked is an extension with A type connectors on both ends. What you need is a printer cable which has USB A Male on one end and B Male on the other. Here is the Egg link for
all USB cables and here is the one for just
printer cables.
I'd say that the Rosewill or Generic black 10 footer USB 2.0 cables would match the printer best and give you some flexibility of placement over a 6 footer. Get the black 15 footer for even more flexibility of placement. It's easier to hank up the excess if it's too long than to make a too-short cable longer...
The Canon 4300 and many other of their better general purpose printers use two blacks . One is dye based to better match the dye based color inks for photos and graphics. The other is pigmented for crisper text document printing (remember that a lot of printing that may look like text is actuall graphical - that's why my photo black is drawing down faster than the others - files like PDFs are almost all graphic files, and I print out a lot of PDFs).
And if you use the duplex (both sides of paper) printing feature, either automatic or manual, you will be using photo black instead of text black. I think Canon did that because the photo black soaks in better and dries faster for less smudging and/or transfering to the feed rollers.
