Cannot access port (in use by another application)
There is a device conflict. This might occur if another device is installed on your computer and
running status software. The status software dominates the parallel port on the computer and will
not allow the HP LaserJet 3300 to access the port.
Try the following:
●
Disable all of the status windows for other printers.
●
Make sure that the printer’s port setting is correct. Access the port settings on the Printer
Properties Details tab.
