Honeywell 1900G-HD (High Density) 2D Barcode Scanner with USB Cable

Can I use this in offline inventory mode, then later connect device to computer using usb to upload data

Is there a way to increase the distance for scanning? We have a 12,000 sft warehouse and my staff will need to be able to scan anywhaere in the build

Does this scanner read codes that are laser marked (black) on metal (somewhat reflective) surface?

What is the working range / distance from usb connection of this scanner? i want to scan things about 40 ft away from my computer.
