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
| Code: | lpinfo -v

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. |
