I have two network printers and all of a sudden when trying to print to them I get an error message in cups:

I restated cupsd, did not change any setting.
I can ping the printers IP, printing from Virtualbox "Windows" Prints OK

I was trying to follow gentoo: Driverless printing

running: | Code: | | lpadmin -p foobar -E -v ipp://10.0.0.106/ipp -m everywhere |
did not create foobar.ppd
| Code: | ls -al /etc/cups/ppd/
total 152

While CUPS would like everyone to use driverless, it doesn't always work.
My printer, a Brother HL-2280DW, is not compatible as CUPS needs a secure ipp connection but my printer does not support the certificates.
I'm rather screwed if CUPS completely removes ppd support which I run through Gutenprint (unless some other method has a way around it). |

I downgraded to net-print/cups-2.4.6 but still get same error message when trying to print: Unable to locate printer
This Cups is total screw-up! |

Seems like some sort of name resolving failure. When I changed the printer connection,
from:
| Code: | | lpd://brother-5370/BINARY_P1 |
to using IP address:
| Code: | | lpd://10.0.0.106/BINARY_P1 |
It prints fine. |

Mine put some weird hostname in the url, I simply created an /etc/hosts entry '<ip address> brother-mfd' and used that name in my url.
(After fixing the IP Address being handed out by my local router DHCP, so the printer got the same address every startup)
Same problem however, name resolution. Well done.
