I have a small GTK 3.0 project that throws an error when displaying the print dialog. The offending statement is the following:
gint res = gtk_print_operation_run(operation, GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG, GTK_WINDOW(data_passer->application_window), &error);
The error is
** (deposit_slip:16703): WARNING **: 18:16:42.872: failed to get find a colord device: The name org.freedesktop.ColorManager was not provided by any .service files
I'm running the program on the Xfce desktop.
What causes this error?
