Thanks for the OS X-related information. The way options get re-purposed on some commands can be confusing. I see that Wine uses the lpr mechanism to send print jobs to CUPS and the CUPS documentation says that it uses UDP broadcasts to advertise its print services to clients. Presumably this is how Wine finds out which printers are available. Can you, or anybody else confirm this? If that's the sole way Wine finds out about printers then a note on the CUPS site about CUPS and OS X is relevant here,. It says: <quote> Due to user interface changes in Mac OS X 10.5, CUPS shared printers will not automatically appear in the print dialog. Instead, you must first run the following command to enable CUPS browsing on your system: cupsctl BrowseRemoteProtocols=cups Then choose each of the CUPS shared printers you want to see in the print dialog by adding them, either from the Add Printer... item in the print dialog or from the Print & Fax preference pane in the System Preferences window. </quote> So, another question for the OP - have you done this?
