If you use Mac OS >10.10, you can find printers nearby using the Printing Services page: https://printservice.web.cern.ch/printservice/UserTools/PrinterList.aspx. You can configure a printer queue for the selected printer directly from this page.
You can as well use the Mac Self-Service which will take care of downloading and configuring appropriate drivers for a chosen printer.
More information about Mac Self-Service and how to enroll your Mac is available here.
In case the printservice page and the Mac Self-Service do not work for a given printer, instructions on how to manually configure a print queue on Mac OS X are available at https://espace.cern.ch/winservices-help/Printing/ConfiguringPrinters/Pages/AddaPrinteronMacOSSystem.aspx.
