Ok so trying to get inkcut up and running on Ubuntu 18 and have installed the standalone inkcut 2 and have it running and have installed the inkcut exention files to the .config/inkscape/extensions folder but when I restart inkscape and check the extensions, it does not show up on the list. I have checked and the files are there for sure. Not sure where I am going wrong. I am no linux expert , for sure , but do know my way around it. BTW I am trying to print to an old Roland PNC-1100 through a usb/parallel converter.
