I am not sure what changed in the current packages, but brlaser stopped working for me.
Cups thinks it was able to print, and the printer LCD still says it is receiving data, but nothing is actually printed. I have tried setting LogLevel to debug in cupsd.conf, but found nothing interesting in the logs. The first two filters were pdftopdf and gstoraster. I tried running both manually and got readable pdf and raster files (according to https://github.com/michaelrsweet/rasterview.git). Not sure how to debug the output of rastertobrlaser. I was able to get the printer working by changing the driver to "Generic PCL 6/PCL XL Printer Foomatic/pxlmono". The printer description is at: https://support.brother.com/g/b/spec.aspx?c=us&lang=en&prod=dcpl2540dw_us_as Cheers, Rafael
