Seeing this issue also. We use Macs in a Windows AD environment, where printers are shared out by one of our domain controllers. We can connect and see the printers, but adding them through the wizard results in nothing being added to the list. Nothing added within CUPS either. We observed this behaviour only in High Sierra so far.
Tried the following, to no avail:
- reset printing system
- tried different drivers (between HP or generic)
- Local admin account and a domain account
- unbinded from domain and rebinded
- Replicated issue on a fresh install
