Old laptop had almost ground to a halt so purchased new Hewlett Packard TS13 with Windows 7 Home Premium. Instructions say that, on connecting with printer (HP6940), the system will automatically detect and install it. It did not do this, so went through manual install procedure. Messages say that the driver has been downloaded and the printer installed as default (confirmed on printers & devices screen), BUT everytime I try to print it won't and flags an immediate error message. Have tried deleting item(s) in print queue and uninstalling and reinstalling printer several times without any success. Diagnostics indicate a "connectivity problem". Is this a problem with the printer to computer USB cable connection or what..........? Why didn't the laptop detect the printer automatically? Help please!!!
