My Samsung C410W printer worked perfectly with 18.10 (Ubuntu and Xubuntu) but now fails after upgrade to Ubuntu 19.04.
I have seen multiple different error messages when I try to print, including
SPL-C ERROR - FALSE
SPL-C ERROR - uw_color < 5
SPL-C ERROR - Insufficient Memory
My SPL-C version is 5.59 05-04-2012
The printer works perfectly from Windows 10 and if I boot to an older version of Ubuntu (e.g. 18.10)
I have tried uninstalling and re-installing the Samsung drivers uld_V1.00.39_01.17.tar.gz and uld_v1.00.36_00.91.tar.gz, but to no avail.
