<SOLVED> Samsung M2070FW - Mint 19.1 - Wifi print problem

[BobSmith72]

Issue with printing to via WIFI to Samsung M2070FW printer.

I'm using Mint 19.1 on two Lenovo laptops with the proprietary Samsung/HP driver.
Printing works fine when connected with USB.
On Wifi, the test page prints correctly but printing any other document produces gibberish code. Its starts with "UNIRAS" followed by one line of gibberish per page.
It worked fine on Mint 18.x.
Any ideas?

Resolved
by choosing Connection: Appsocket / JetDirect when adding the printer.
