I used CUPS every time since LPD is a confusing thing for me. I mean I was never able to make it print. My Brother network printer shows this at Protocol section:
Web Based Management (Web Server) HTTP Server Settings SNMP Advanced Settings LPD Advanced Settings Raw Port IPP HTTP Server Settings AirPrint Advanced Settings HTTP Server Settings Mopria Web Services Advanced Settings HTTP Server Settings Mobile printing for Windows Google Cloud Print Advanced Settings Proxy Advanced Settings Network Scan SMTP Advanced Settings FTP Server FTP Client TFTP mDNS Advanced Settings LLMNR Ironically I'm not able to say if it can accept PostScript or LPD or ... too confusing. I tried /etc/examples/printcap with my settings filled in from internet examples, it never worked. I tried your example here, it doesn't like it.
