ERROR: Shinko CHC S2145

[SebastiaanRobbrecht]

I installed the gutenprint drivers on my raspberry pi 3B to drive the Shinko CHC-S2145. The raspberry pi detects the printer and I can select the driver via gutenprint. But when I want to test the printer it gives no sign of life. Anyone experience how I can solve this problem?

When trying to print a testpage i get this message "Invalid backend (shinko-chc2145)"
