Dell 1720dn printer PPD file

What a struggle. All I wanted was a working PPD file for the Dell 1720dn. I searched google high and low without luck. Finally I found a reference to a Windows PPD file for the 1710. It was on driverguide.com, which made me jump through flaming hoops to download it. It’s attached to this post and seems to work ok for the 1720dn.
