HP 3700 Series print failed filter
Trying to set up an HP 3700 series printer/scanner and I am consistently getting the dreaded "Printing - filter failed" error. I have been to this thread and followed the authors steps/solution exactly, but to no avail.

The system can find the printer, see the ink levels, etc. ... It just won't print and says the printer is not connected via WiFi and then print.
I am running a 2008 Mac Pro with High Sierra (patched).
Anyone else have another possible solution?
