the usblist2.exe is the file that comes with the driver download zipped file.
unzip it to a folder, open that folder and you should see the release notes, also the .hd file in the same folder as the usblist2.exe
edit: when you follow the steps above, at the point when your printer says wait & image, this is the time to run the usblist2.exe on your computer that the printer is connected to by USB.
Go to this link and download the newest software for your model. There should be 3 different files. Use the extract feature on your File Explorer and you will see the file has an .hd extension. Windows 10 doesn't like .hd, but no problem: Samsung thoughtfully provided a software to open it (the usblist2 or similar file).
Power down the computer (If the keypad is locked on the printer like mine was, unplug it). With the power off, press and hold the red Stop/Clear key , then press the Power key (or plug the printer back in) and check to see that the printer display says "download mode". Then, in the download file (use the thumbnail view), drag the M2070FW…hd file into the usblist2 (or similar) file. A black file box will open, you will see the .hd file open and the numbers run until done, then the black box will close. Watch the printer display screen, it will begin the firmware update and show the progress in %. Do not shut off the printer. The printer will reboot and print whatever documents came with the .hd file. Voila!
I am not particularly tech savvy, and I had to piece together information from various sources before all the steps came together. Hope this helps.
I have applied instructions to update the firmware and I have seen the data on the small DOS screen during the loading, but the only result I finally get on my printer's display is "Image error, Reset printer". I seems that something is corrupted. I have tried with revisions V3.00.01.33 and V3.00.01.37 but none of them work.
