README 1st for DNP DS620 Printer Firmware v4.33 Update Utility for Windows


General Information: 
This firmware update utility will install v4.33 firmware onto the DS620 or DS620A 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. 

Important Note: 
The v4.xx firmware is backwards compatible. It is supported in all current and older gen DS620 printers. 
However, the new v4 generation DS620 printer with identified by Serial Number prefix "DA6C"xxxxxxxx and "DB6C"xxxxxxxx cannot accept older v1.xx firmware versions. 
The previous gen DS620 printers have a SN prefix "DS6C"xxxxxxxx and "DS6X"xxxxxxxx can accept the v4.xx firmware or older v1.xx firmware.

The DS620 v4.33 update utility supports Windows 7/10.
