So when I set up my Brother laser printer, I followed the wiki at https://wiki.debian.org/CUPSDriverlessPrinting#Creating_a_Driverless_Print_Queue_with_lpadmin_.28Short_Version.29 using the cups-filters PPD generator option (for reasons I do not remember). The device has the name ipp://Brother…._ipp._tcp.local/ so I expect I'm using mDNS to print to it. The printer has an IP name and address (in /etc/hosts) that I use solely with ping. (A pingall function tells me which devices are turned on, and need switching off before a thundestorm strikes.) lpinfo also sees an lpd: ?device with what looks like a serial number (but isn't AFAICT). Which wiki method would I use to set up this printer through its IP address rather than a .local address? There's a lot of material in the Debian Printing wiki pages; so much of it is aimed at buster and legacy printers that finding particular methods can be difficult. I have a second, older printer whose printing engine is dead. (I use it only as a scanner.) The driverless command also gives this printer a .local device name (both ipp: and dnssd:), but I also see a socket://192.168.1.11:9100 address that I understand is deprecated. However, this is the only IP address given by lpinfo -v. In fact, it's about the only IP address I've found in the CUPS configuration files. I don't see 192.168.1.12 (the Brother's) anywhere. Cheers, David.
