HP services slowing down stuff, a possible workaround
I use a Lenovo T500 for regular stuff with relatively low gfx requirements. Recently I got a used HP Colour Laserjet printer CM1312. After installing the drivers (network) there is a 20-30 seconds delay on the Wifi initialization on the laptop. Only on startup.
Now I am aware of HP drivers/apps slowing down systems so I located the starting services in services.msc and changed startup mode from Automatic to Manual.
This was relevant to two services that was called:
HP LaserJet Service C:\Program Files (x86)\HP\HPLaserJetService\HPLaserJetService.exe
HP CUE DeviceDiscovery Service C:\Windows\system32\svchost.exe -k hpdevmgmt
Both was set to Automatic and after the changes the delay was gone.
This may of course be achieved by disabling them altogether, but that may have an impact on the ability to reach the printer.
Note: The "Cue" service may be disabled alltogether according to a reply on HP Support Forums:Just sharing info...The "job" of that service is to identify all newly connected HP devices and configure them to be used with the HP Solution Center program. If this is the only HP device you'll use with this PC, then you can disable it from the Services list just like you disable any other service. don't forget to stop it first.
