When printing from Apple Mac OS 10.6 Snow Leopard to a Microsoft Windows hosted PaperCut server, jobs show in the release station and Job Log with IP addresses instead of hostnames in the client column
When a print job arrives at the PaperCut server it may have an associated IP address but no client hostname. When this happens PaperCut does a reverse lookup to find the client hostname, which can be useful information to display on release stations and in the Job Log. If you experiencing the above issue, the likely cause is the failure of the server to resolve the client hostname from the IP address associated with the print job.
Generally hostnames on larger networks will be resolved via DNS (and/or configured via DHCP), so if you experience this issue you may need to check your DNS configuration.
An alternative to DNS is to use WINS resolution to resolve client hostnames from IP addresses. WINS resolution will be attempted by the Windows server but is not enabled in Mac OS 10.6 by default. If you were not seeing this issue previously with your Mac OS 10.5 (or earlier) clients, it may have been because WINS resolution was enabled. To enable WINS resolution, enable the option at:
File Sharing(list item, ensure that it is checked On) →
Share files and folders using SMB (Windows)(checkbox).
AFP and FTP may be kept disabled.
Enabling this file sharing option starts the SMB service, which in turn starts the Samba daemon responsible for WINS resolution.
