Hello, everyone.
I am examining the systems configuration by a print server "EW2500 (J8021A)" and "HP LaserJet Pro 400 color Printer "M451 dn(CE957A)".
However, "EW2500 (J8021A)" is not supporting "M451 dn(CE957A)".
Someone should teach me how to recognize "M451dn", by "EW2500 (J8021A)"
For example, update of firmware, etc.
Thank you.
