README DNP DS40 Printer Firmware v1.61 Update Utility
2020-09


General Information: 
This firmware update utility will install v1.61 firmware onto the DS40 photo printer.  Installing this firmware may add functionality or modify printer behavior for improved functionality.  
Installing the most current firmware version will include all improvements of the previous firmware updates.  Installing each of the incremental updates are not necessary.  

The firmware update utility for Windows supports OS 7/8/10.

The firmware update utility for Mac OS-X supports versions 10.13, 10.14, and 10.15 Utility may operate on previous Mac OS back to 10.10 but older OS is not supported.

Ensure the printer is Idle and has print media loaded.  
After unzipping (ZIP) for Windows OS and or opening the disc image file (DMG) for MacOS, copy or save the contents to your computer desktop. Review the update installation information, then run the update application file.  

Instructions:
1 Confirm your DNP printer is connected and powered on  
2 Download the firmware update file
3 Unzip the file that was downloaded (Without this step, the update tool will not run)
4 Select the folder that matches your operating system, 
	For Windows, select either 32bit or 64bit 
5 Double click on the application file, DS40_0161x86_Direct or DS40_0160x64_Direct.  You should see only one application file, the name will depend on the folder that was opened.
6 Follow the directions of the application as prompted.

For Mac Open the Disc Image and access the update file and User Guide. Review the instructions. 

NOTE: The LEDs on the printer will flash while the firmware is being updated.

- The printer will "beep" several times during this process. 
- The computer display will show the update progress.
- Wait until the update process has completed.  
- DO NOT interrupt the process.  The dialog box will indicate completion.  

- The entire process will take about a minute to complete.


IMPORTANT CAUTION NOTE:  

DO NOT turn off or disconnect the printer or PC during this process once it starts. 
DO NOT try to make a print or change media during this process.


Note: 
Some new features require the complementary printer driver update to enable and use the functions.  

Operation notes – USB iSerial:
The DS40 does not support iSerial functionality and certain connection limitations apply to PC with modern OS.  
For Mac OS, only one DS40 can be connected to the Mac at a time and no other DNP printer can be connected.

For Windows PC, it is recommended the printer is always reconnected to the same USB port for the printer, else the PC will assume it is a new printer being connected and will create a new driver iteration; repeating on another port will cause multiple iterations of the driver to appearing the control panel for printers, e.g. DS40 Printer-1 or DS40 Printer-2, and so on. Avoid this by reconnecting to the same USB port.
