Mac started up when I turned on printer

I was surprised today when I got home and turned on my printer before I turned on my imac and the imac automatically powered on. I am certain that I completely shut down my imac before this happened. My question is is it possible for my Canon printer to power on my imac or did I accidentally leave it in sleep mode and was it just waking up and not powering up? Can the printer power up the imac or am I mistaken and was it just waking up?

This is not harmful to the computer is it?
It isn't; an iMac is designed to be left on all the time except when it won't be used for several days or something is being done which requires it to be shut down.

My Mac Pro starts up when I turn on the power, BEFORE I switch it on with the button, why? Plus, my computer keeps freezing and blacking out.

My Mac Pro starts up when I turn on the power supply (when I plug it to the outlet), BEFORE I switch on the button on the computer, why is this happening? Plus, my computer keeps freezing and blacking out and I'm forced to restart it, that's when the compter starts on its own when I turn on the power.

Hello Engender,
I should have followed up with a progress report because I eventually eliminated all the problems I was having with my Mac Pro, now it's behaving like a new computer… beautifully. I did originally take Grant's advice above, changing the setting that I had in the System Preferences > Energy Saver but that only stopped from rebooting on its own when I shut down my Mac properly. Otherwise it continued to restart on its own after freezing or crushing when I switched on the power. I took my machine to the Apple Store and after many tests they couldn't find anything wrong with it. I was very depressed about the whole business.
It was after going onto many of the other Apple related websites that I discovered that it wasn't a faulty power switch or fan, as as I originally thought, but found out that my problem was related to the Graphic Card and possibly I did not have enough ram (I had the original amount of 2 GB). The original card that came with the computer: 512 MB ATI Radeon X1900 XT was over heating and forcing my machine to shut down, I think it was because I had upgraded to OSX Lion which on its own requires at least 2 GB of ram to operate well. I added 4 GB of Ram to the 2GB I had (4GB kit (2GBx2), Apple 240-pin FBDIMM, DDR2 PC2-5300 upgrades for Apple Mac Pro (4-core) 1st Gen. - 2006-2007 Desktop/PC, CT579443 from Crucial.com about $160 for the set) and replaced the Graphic Card with ATI Radeon HD 5770 1024 MB from Apple (around $260), (ATI Radeon HD 5770 Graphics Upgrade Kit for Mac Pro (Mid 2010) - Apple Store (U.S.)) This card works very well with my original Mac Pro 2008. I installed it about two weeks ago and no problem with it starting on its own, over heating or freezing. OSX Lion works well and I'm thinking of upgrading to Mountain Lion once I learn that my Mac Pro 1.1 will work with the new hardware I installed.
Your problem could just be the power cord but I agree with you that doesn't sound right, when I mentioned faulty switch I meant the part where the power cord meets the power button, the unit which houses the power distribution, I thought at first that it could be faulty but changed my mind because of the computer overheating.
I don't know if this is of any help to you but I hope your trouble will be solved with the new cord.

How can i disable imessage from automatically starting up when i turn on macbook air?

how can i disable imessage from automatically starting up when i turn on macbook air? i dont know my imessages to pop up on my laptop when it turns on. But i dont want to disable imessage totally on my macbook.

Welcome to the Apple Support Communities
First of all, check that Messages is closed when you turn off your MacBook. This is so important because, by default, OS X will reopen all opened apps the next time you start your Mac.
Apart from that, when you go to  > Shut Down, or  > Restart, in the window you see to restart or turn off your MacBook, unmark "Reopen windows when logging back in". This will avoid that your Mac opens all opened apps the next time you start the MacBook, so Messages won't start automatically at startup

My computer suddenly refuse to start. When I turn it on it gives the startup sound but the screen is grey and after a while a little folder icon with a question mark inside turns up. It doesn't blink. What to do? Nothing happens if I try to start up from

As I say my computer, a mac mini refuse to start. When I turn it on it gives the startup sound and the screen turns grey and stay that way for a long time. And in the end a small folder icon with a question mark inside (it doesn't blink) turns up in the middle of the screen.
I have tried to start up from the installation CD holding down the C key on the keyboard. Same result. I have tried different key combinations while starting up. No result or rather same result. Nothing. Is the computer suddenly dead?
I was about to buy a new computer but I need access to my data on this one (I write this on an iPad) but hven't yet found a way.
Anybody have any good advice?
I thought it was a software problem, that the computer couldn't find the startup software or something and maybe it is, but I am beginning to fear that it could be a hardware problem.

You need to re install OSX. If you have the dmg file downloaded via torrentz this is how you can create a bootable external HD or Flash drive (8 GB+)

How many beeps do you hear?

I'm sure this is a setting fix, but can't find it-. All of my windows for mac programs open when I turn on my computer, such that I have to close each one individually to get to my desk top. How do I adjust so none of them open unless I choose to?

In windows 7, how to make firefox start automatically when I turn on the computer

In Windows 7, how to make Firefox start automatically when I turn on the computer. Note, I am asking how to do this with Windows 7, not xp, not vista.

You need to place a shortcut to open Firefox in the Start > Programs > Startup folder.<br />
That is basically the same in all Windows versions.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

In windows 7, how do I make firefox start automatically when I turn on the pc

That worked, thanks. When I turn on the pc, I almost always go to the internet before anything else, so this eliminates one step. It doesn't seem to save any time, however, but it is easy. If anyone else wants to try this, it looks like it's very easy to undo if you change your mind.

My computer tells me I purchased the Rod Stewart Christmas album, but I did not. How can I get iTunes to cancel this "purchase". Also this thing has just started playing when I turn on my computer, how do I stop it?

My computer tells me I purchased Rod Stewart's Christmas album. I DID NOT. How do I get iTunes to cancel the purchase. Also, this thing has suddenly started playing when I turn on my computer. How do I make it stop?

It is probably too late to cancel it, but contact the iTunes store support staff at http://www.apple.com/emea/support/itunes/contact.html and see what they can do for you.

Go to System Preferences>Accounts and then select your account, then startup items, remove Word from the list and reboot, you should be fine then.

How do I get a program to start up when I turn my computer on?

You know how in the dock, there's a little triangle under a program that's technically running even if you don't have a window open? Dashboard and Finder always have that triangle after start up. How do I get another program, like Safari to "start up" with that triangel all the time even if I don't want to have the browser window open when I turn my computer on?

Open the Accounts pane of System Preferences, add it to the list of login items for your account, and check the box to hide it. Some applications, such as Mail, ignore the box in Mac OS X 10.4 and are always visible when launched; in this case, an AppleScript can be used to hide them.

Can I get my mac to wakeup when i want to print

I am printing using Printopia which requires my IMAC to be on. When it goes nto sleep mode of course it will not print. Is there a wakeup program?

Have you tried the support forums on the Printopia site?
Of course, you can leave your Mac on continuously; or you can go into Energy Saver Preference Pane in System Preferences and see if checking "wake for network access" might work or you could set up a Schedule in that Pane. The wake for network access may work if you turn on printer sharing and network in the Print & Fax Pane.

Error message when i turn on printer

I have a HP Photosmart C7280-CC564A All in one printer and when I turn it on I get blue screen on printer with B24C1700 on it and
you cannot go any further. It will not clear out message. Also on front of printer the blue flourescent light on what looks like a camera is flashing. Nothing is in the card readers next to it.

HI,
You might try resetting the printer. The document linked hear isn't your exact error message, but it contains the reset instructions that might clear this up for you. Try the steps especially about removing the cartridges and power cord.
