SOURCE: Initialization failed - Unable to acquire TWAIN-compliant device
Hello, 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. You can email me at [email protected] if you need further assistance. Bye.
SOURCE: USB device not recognized
From your description above it seems the problem is not with the USB as other devices are functioning correctly.
The main cause may be the Device drivers for the printer, the device drivers may get corrupted, make sure you have the latest drivers, download the latest drivers from the manufacturers site and install the driver first before attaching the printer cable to the PC/Laptop.
