Are you always working with your computer and printer?

When I woke up this morning, I have got a really bad headache! I don't know why, I slept less than 8 hours  and perhaps it was the caused. Or perhaps I have had a bad headache because  I was  sitting in front of the computer and writing too much, I have written  almost 10 articles for 8 hours straight, and one thing that pissed me off  was I was  about to print  colorful documents, but  unfortunately we don't have a colorful ink/printer, only black and white. Speaking of printer, this Canon Printer Ink would be perfect on my computer printer and your computer printer as well, though a color printer is not inexpensive from cartridges to inks but of course a colorful inks/printer is very useful and different from black and white color ink. Are you always working with your computer and  printer? How does the printer important to you and to your business? Are you using  a colorful ink or just  a black and white ink?  Indeed, Canon Ink is very common, it is usually being used by majority, or users who have a computer and printer.
