Things you should know
Sometimes a visitor label printer will not operate as intended if it sees no activity for a set time. In other words the printer has been idle for 30 minutes, 1 hour etc.... The result of a printer in an 'idle', 'time-out', or 'sleep mode' state is the visitor does not receive their visitor pass. Meanwhile the print job sits in the print queue and once the printer is 'livened' again, all these queued print jobs start printing.
Three things to check to resolve the issue
1: Printer Sleep Mode: Check to make sure that the printer itself does not have a sleep mode function set to 'enabled'. This can be determined by going to:
- Control Panel > Devices and Printers
- Right-mouse click the printer in question and select Printer Preferences and look for an option to disable sleep or time-out mode.
- You can also right-mouse click the printer in question and select Printer Properties and look for a similar function.
- You may need to refer to the printer Help files or manufacturers support desk for assistance on this.
2: Power Options: There is a setting in the Windows Power Options, Advanced Settings that forces Windows to keep USB ports 'live'. Make sure this is enabled as follows:
- Go to Control Panel and select Power Options
- Click Change plan settings for the selected Power plan
- Click Change advanced power settings
- Expand USB settings and then USB selective suspend setting and change the setting to Disabled for the option for On battery: or Plugged in:
- Click OK on the Power Settings window and click Save changes on the Edit Plan Settings window
3: USB Device Manager Settings: The "Allow the computer to turn off this device to save power" setting in Device Manager may be enabled.
- Click Start, type Device manager in the Search box and then click Device Manager from the returned list
- Click to expand USB Root Hub and click the Power Management tab
- Uncheck the option to Allow the computer to turn off this device to save power and click OK
Note: You may see multiple listings for USB Root Hub, uncheck this option for all USB Root Hubs.
- Close the Device Manager
