It does not seem to be a kernel problem. I changed to kernel 18.104.22.168 which I use in VL-59/58 and does print there, however, not now in VL5.9.1.
BTW this is a parallelt printer. I will try now to connect to USP port.
Did not print as well.
However, now I found the culprit. File /usr/lib/cups/backend/epson was missing. Copied it over and now both parallel and USB ports do print.
