LinuxQuestions.org - Brother MFC-J4510DW does not print although print jobs complete successfully

I am having a weird problem with CUPS and my Brother printer. Whatever I print gets entered into the printer queue and completes successfully, yet the printer sits there idling and does nothing. Scanning works!

I re-installed the printer using different methods and different URIs, it is always the same result (unless I specify a wrong URI of course).

Method 1: http://support.brother.com/g/s/id/li...ion_prn1a.html, using an lpd:// URL.

Method 2: https://gist.github.com/ragusa87/89806ffba57ef9f5a67a, which is basically the same, just with an ipp:// URL.

Here are a few debugging commands:

Code:

root@wzb-PC:/home/wzb# /usr/lib/cups/backend/snmp

network lpd://BRN30055C2C6AED/BINARY_P1 "Brother MFC-J4510DW" "Brother MFC-J4510DW" "MFG:Brother;CMD:HBP,BRPJL,URF;MDL:MFC-J4510DW;CLS:PRINTER;CID:Brother IJ Type3;URF:SRGB24,W8,CP1,IS1,MT1-8-11,OB9,PQ4-5,RS300,OFU0,DM4;" ""

Code:

root@wzb-PC:/home/wzb# lpinfo -l -v

The CUPS error log and a few screenshots are attached.

I would be grateful for any hints and suggestions.
