How do i Download an app with a Calculating ability


Hello Emmazone,

Depending on the amount of calculation you will need to do, you can always search for "Calculator" in your app store, or you can go for something a little more powerful, such as this: http://products.wolframalpha.com/mobile/

Comment:
I've had this printer for over a year now. I have it set up wirelessly connected to my network. The biggest problem I have is that I have 3 computers in the household and sometimes, for whatever reason, this printer will not realize it is done printing from the last job and will continue to think that it is working. So, when you go to print to it from another computer, you get the Another computer is using the printer. Please wait. This will continue until you go and turn the printer off and wait for the insanely long turning off cycle, then turn it back on. <br /><br />Once you do get it working, it gives you great output for both text and photos. I have been doing a lot of scanning old black and white family negatives and printing them, and my family members thought the prints were from a photo lab. <br /><br />Bottom line: if you want excellent output and have a tolerance for quirky connections, you will be OK with this. If, like my wife, you just want it to work like an appliance, and find the locking up infuriating, I would not recommend it.

Comment:
As rated by CU, it produces very nice photo prints. Text quality is also good when set on standard but not so good on fast. It takes it's time to get started when you send it something to print, whirring and clicking for a good minute before anything actually prints. My main complaint is paper handling. I sometimes print mailing labels from sheets. My previous printer, an HP 7560, would accept a sheet with an upward curled front lip. The Canon iP7220 either doesn't accept it or jams up solidly.

Comment:
Tried brochure paper and spent two days trying to get color right. Used glossy and matte photo paper for great print results, mostly. color shifted for no apparent reason. First batch of matte paper worked great, others jammed every 2-5 sheets. Will not pick up matte paper sometimes, gets worse the more I try.

Can you insert like letters and solve algebraic equations?


Not with that calculator. You can use Wolfram Alpha to solve most equations very quickly: http://www.wolframalpha.com/input/?i=x^2+-+3x+-+4+%3D+0

You can even use it to solve systems of equations: http://www.wolframalpha.com/input/?i=2x+%2B+3y+%3D+5%2C+4x+-+3y+%3D+1

Enjoy.

Hard drive crash


The guy that told you it would only cost $40 is not telling the truth. Windows XP runs around $125.00. If you download an operating system from the web, Microsoft can see that your copy of Windows is not valid and disable your system from a remote server. I recommend buying Win XP from Best Buy. It is currently on sale until Jun 26, 08 for $99.99.
