SNMP backend suggests IPP for Dell 1700n, but only LPD works

See following report at Ubuntu:

https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/107824

The user sets up a Dell 1700n with the URI

ipp://192.168.1.3:631/ipp

which was suggested by the SNMP backend (and therefore listed under the auto-detected printers in the gnome-cups-manager). Independent which driver he chooses (PostScript, pxlmono) the printer does not print.

Setting it up manually with the URI

lpd://192.168.1.3

makes the printer working perfectly. Also accessing it via a SMB share on a Windows box makes it working.

Either the IPP backend needs to be fixed or in the SNMP backend for Dell printers LPD URIs should be suggested.

Dupe of STR #2035, deferring to CUPS 1.3.

Basically, that 1700n needs a firmware update to support IPP, and the current rev is broken.
