Thank you all for the suggestions. I have the printer working ( for now at least
@ilu Tried the terminal commands you suggested . I could ping the printer no problem . sudo lpinfo -v couldn’t find anything other than the CUPS-pdf printer which is already installed . I suspect that this is a shared printer and might be why the printer settings dialogue I mentioned last night was showing a domain and samba i.e. the printer settings probe was finding the shared PDF printer.
@Ghstryder and @mhwelsh. Decided to go with mhwelsh suggestion to use the localhost:631 webinterface ( which should be distro neutral). Appsocket and ipp protocols seemed not to work ( for me at least) . LPD/LPR worked (
) . The format was lpd://192.168.x.x/ ( appending lp and lp0 also worked so not sure exactly what queue I am using).
Offtopic : Regarding password my own account and password worked when requested on the CUPS webinterface ( presumably because it has sudo privileges and is therefore effectively root ?). When I was with Debian vanilla the accepted school of thought seemed to be to have an actual root account and to be honest I found this more straightforward . To do anything administrative you logged into a root terminal and then back to own account when finished . This leaves one more conscious of being root only when really needed - you could always set up minimal sudo privileges if necessary. At least this way if your own account was compromised an attacker would not have root access.
