I can not cancel print job for a HP officejet 8500 in windows 8
This question was solved.
View Solution.Hi,
From the Desktop, hold down the Windows key and press R. Into the Run window, type services.msc and hit enter. Browse down to the print spooler service, right click it and select Properties then click on the Stop button. Now browse to C:\Windows\System32\Spool\PRINTERS and delete the job inside this folder - You may need to click a prompt to gain the appropriate authority to open the PRINTERS folder.
Restart the computer and you should find the document(s) have been removed.

HT4356 Can I air print from hp officejet 8500 wireless to ipad2?
Do I need to download an app for air printing from wireless hp 8500 printer to ipad 2?
The 8500 models that support AirPrint are :
HP Officejet Pro 8500A e-All-In-One A910a
HP Officejet Pro 8500A Plus e-All-In-One A910g
HP Officejet Pro 8500A Premium e-All-In-One A910g
If it's not one those then yes, you will need an app. HP have their ePrint app which might support it, otherwise there are third-party printer apps such as Print Central For iPad and Print n Share which might work with it. -
On a Mac, can you navigate menus with one handed key strokes like Windows?
On a Mac, is there anyway to navigate menus with one handed keyboard strokes like you can in Windows? My girlfriend is a graphic designer and switched from Windows to Mac. She misses being able to use the Alt key and make menu selections. On Windows she can press "Alt" and then move through menus and submenus with one hand on the keyboard. When you press "Alt" the first letter of every menu is highlighted. When she presses a certain letter the menu drops down, and the first letter of every submenu is then highlighted. She can then navigate through all the submenus until she hits the selection she wants, all using the left hand on the keyboard. It's very fast and efficient. Can you do something similar to this on a Mac?
The reason she wants to do this is because when she is in Photoshop, she likes to use her right hand on the mouse with the cursor inside the canvas (sketching, moving layers around) while she makes menu commands with the left hand. It is 10 times faster this way than using the mouse for everything. Hot keys are not the same because you must have those memorized. With the "Alt" key function, you can open a drop down menu, see the choices, and make your selection.
I have been a Mac person my whole life, and I have to say, it's a pretty awesome function. I really want the Mac to have something similar.Barney-15E wrote:
[Actual studies|http://www.asktog.com/TOI/toi06KeyboardVMouse1.html] have found it is faster to use the mouse to make command activations than using keyboard shortcuts.
The 20-year-old argument on that web page isn't very convincing. Keyboard shortcuts are certainly faster for experience power users who do the same thing every day. The mouse is faster only for new users or users doing non-repetitive commands every day.
It is interesting that one of the posts on that page said this:
I remember one mainframe company in the sixties that came up with the following command-key guidelines:
Use the first letter of the command word
If the first letter is already used, use the last letter
If the last letter is already used, use the second letter
If the second letter is already used, use the second-to-the-last letter
etc.
This is actually very similar to how the keyboard-driven menus work in Mac OS X. The advantage over the Windows method is that when there is more than one command in a menu that shares the same first letter, you do not have to memorize which command uses which letter. You just type ahead until the correct command is selected.
I would, however, encourage Derek Doublin1's girlfriend to learn the direct keyboard shortcuts in Photoshop. On Mac or PC, for me pressing Command-Option-I is much faster than either the mouse or using the keyboard to drop the Image menu and walk down to the Image Size command. -
Can you do anything with a .band file on a Windows PC?
I am in a music production class in school where we use Macs. However, at home I can only use a PC running Windows 7. Obvoiusly there is no Garage Band program for Windows. I was wondering if it was possible to import the .band file into the GarageBand iOS app. (I have a 4gen iPod Touch.) If not, then is there anyway I can make the file useful? I know that if you open the .band file (Which appears as a folder) you can get some of the recording you made with the microphone, but you can't use loops and such.
the only thing you could do is export each track while using GB, the only other software that can open a GB project is Logic

can't sync itunes with iphone via USB, windows 8.1 system
Right click on your device under Portable devices and click on Uninstall and when the uninstaller box pop ups select delete the driver and click OK. Now click on Scan for hardware changes on top of the page and see if you get apple mobile device support driver under USB Devices and if not then disconnect your device from the computer and try to connect it to a different USB port and check also open control panel and select Apple Mobile Device Support from the List and Click on Repair and check. If still the device is not showing under USB then uninstall the following services from your computer.
iTunes
Apple Software Update
Apple Mobile Device Support (if unable to uninstall ignore and move to next)
Bonjour
Apple Application Support
Restart your computer once after the uninstallation is completed and then download latest version of iTunes from http://WWW.apple.com/iTunes/download
Locate the iTunes setup file and right click the file and run the installation file as Administrator and let the installation complete.
Then check if your device gets deteced in iTunes and if still the device is not detecting in itunes then go to device manager and see under Usb if you can see Apple Mobile Device Support Driver and continue with the step. 5 of above given link in my previous post. And if still thedevice is not showing under USB then right click on your device under potable device and click update driver and first check for updates automatically and see under USB if you see the driver now and if not then go back to device under portable device select update driver, let me choose driver from the list, Have disk, browse file in the following location " C://Program Files/Common Files/Apple/Mobile Device Support/Drivers and select usbaapl file and install the same (if you can't find the driver on above location then look for the driver in Program Files(x86) instead of Program files and if you can't find usbaapl then look for usbaapl64 and complete the installation and then restart the computer and check if your device get recognized in iTunes.
Note: when installing the drivers keep the iTunes closed till the drivers installation is completed. -

Can you not print pdf to iphoto anymore with OS X Lion?
Just downloaded Mac OS X Lion.
Can you noit print pdf to iphoto anymore with OS X Lion?From what I am able to determine, the functionality that I enjoyed before upgrading to Lion is no longer available. Previously, one could open a PDF using Preview, select Print and then "Send to iPhoto." This feature is not there anymore. That is a major disappointment as I used it quite regularly at the non-profit support serviceI volunteer at.

I have an iMac running OS X 10.8.3 and have connected an Epson Workforce 2540 printed that is allegedly Airprint enabled. I can connect and print with a USB cable but can't connect via Airprint. My colleague running 10.7 can. Is this a feature of 10.8? Any ideas for a fix?
iOS devices use AirPrint to connect to a supported printer. OS X will use Bonjour to locate and connect to the same printer.
With the Epson connected to your wireless router, when you open Print & Scan and click the plus button to add, does the Epson appear in a small box with a heading of Nearby Printers?
If not and a window appears showing Default, Fax, IP and Windows in the toolbar, do you see the Epson with the Default view selected? -

Hello, we have both Creative Cloud membership and Creative Cloud for team. Can you help me with the difference and if i need to have both? We have 9 employees that are using it. Just not sure if i'm paying for something i don't need.
Thank youPlease refer to Creative Cloud Help | Creative Cloud / Common Questions
CC is for retail use with 20 GB of storage space, CCT is where number of seats are purchased & assigned by one program admin where each seat gets 100GB of storage space.
You can not have both the CC & team in one account as it will only provide you added storage space of 120 GB but you can activate the CC any of them or either of them twice as CC is based on Adobe ID.

Edited by: mshadows on May 18, 2008 7:53 AMI was playing with this a little bit and came up with this game model, something that I'm sure can be improved upon greatly:
TttXO.java
an enum to encapsulate X vs O. I could use a boolean here since it has 2 states, but this seems more intuitive to me
package dy08.m05.ttt;
* tic tac toe encapsulation of X vs O
* @author Pete
public enum TttXO
X, O
}TttCell.java
encapsulates an individual cell in the tictactoe grid.
package dy08.m05.ttt;
* Tic Tac Toe Game cell
* can be occupied or not
* can hold TttXO X or O or null
* @author Pete
public class TttCell
private boolean occupied = false;
private TttXO xo = null;
public TttCell()
* sets a Square for either x or o
* @param TttXO
* @return true if successful, false if already occupied
public boolean setXO(TttXO xo)
if (occupied)
return false;
else
occupied = true;
this.xo = xo;
return true;
public void reset()
occupied = false;
xo = null;
public boolean isOccupied()
return occupied;
public TttXO getXO()
