Dell_user_XPS8500,
Did you recently install/reinstall the operating system on this computer?
Does the Dell V105 printer use Dell All-In-One Center, Dell Imaging Toolbox or Dell Printer Home?
Do you have all the Windows Updates, especially .net framework, needed t run many applications and Download Latest Java
Did you try running Delete Print Jobs to remove any stuck print jobs from the queue, then restart your computer?
