Sorry for the delay.
When you connect via ethernet directly to your PC, can you ping 192.168.0.10? If not then either print server is bad, bad cable, or using a different IP address. Resetting it should change it to the default 192.168.0.10 address.
Are you getting a link light? I know these older devices may require a crossover cable to connect directly to your computer.
Possible the device is defected or has some corruption in the firmware. I am not aware of a way to crash recover/emergency firmware. With most D-Link devices, turn the device off, hold a paperclip in the reset hole and then turn the device on while holding the reset button. In most cases hold for 10-15 seconds and release, The device should go through the boot process.
With your PC statically assigned as you do, try going to 192.168.0.10 or http://dlink-XXXXXX as from my previous post. There is usually a screen to load firmware. If not, then the print server may be dead.
You may want to contact D-Link tech support in your region. They can possibly give you specific instructions on how to fix it.
The US stopped support on this in 2013 so I do not have much information. There is an FAQ on their legacy site on how to set it up. Reset it and try this:
