Question about HP Officejet Pro L7680 All-In-One Printer
Set up wireless and print function works fine. Fax function works too. Receive an error message - no scan options when pressing scan operation button on HP machine. Previously received a 'no communication' message.
The scanner function is not available when you are connected wireless, you must be connected via USB to your PC for the scanner to function correctly.

I have seen your message stating that "Initialization failed - Unable to acquire TWAIN-compliant device" error is received when trying to connect USB-Parallel type to your Laptop.
Well, Printer Panasonic UF4100, recommends to use only " Printer/Scanner Interface as Bi-directional Parallel (IEEE1284) " means you need to use Parallel cable to connect Printer to the Computer/Notebook. You may receive some communication error messages if you are using a "PORT REPLICATOR CABLE"( USB TO PARALLEL connector). The error message that you have received is related to the communication error. Futher, if you use same USB- Parallel cable for long time the Printer Hardware functionality might go bad, since Printer memory gets confused and will not read or detect the Cable , since it is not a cable to use mentioned by Panasonic Manufacturer.
Let me tell you, general functionality of Printer like Printing would work even if you use USB-Parallel cable. But it is not a case with Scanner and Fax functionality.
Hence, I recommend you to use only Parallel cable to connect your Printer to the Laptops.
I hope that this will resolve the issue for you.
