I do not know who is carrying the head, anyway, selling printer without printer cable has become the rules. I have more than once heard that some people forget to buy print lines, go back to the printer, had to run a trip thing. Businessmen will generally focus on your attention in the printer, the initiative to recommend you buy a print line, and said absolute discount. Do not underestimate this little thing, maybe the business to earn money from you to sell that printer to earn more. And a shoddy print cable, may be buried for the future use of the seeds. So the more sensible approach is to find another franchise of the various cable counters, buy a affordable and strong printer cable.

Inkjet printer power supply part of the two design ideas, one is built-in power supply, directly with the power cord to connect the printer and power outlet can be powered; another design using external power supply, the printer itself is no power, by external DC regulator Power supply work.

Single and double canon ink cartridges, refers to the inkjet printer can be placed at the same time the number of cartridges.

Single cartridge models are slightly more complex. There are some models using four-color single-cartridge, that is, single-ink cartridges were stored in black, yellow, goods, green ink, due to uneven ink consumption, prone to a color ink exhausted, the entire cartridge scrap situation; Single ink cartridge design, there are still black and color ink cartridges, but can not be placed at the same time, according to the need to print documents, manually replace the appropriate cartridge.
