FIRST: when you are printing from the wireless network, make sure you have authenticated to the system as described on the page about the wireless networks. Note that only our specific networks know about the printers in our buildings; Eduroam and the generic leiden University networks cannot access our printers.

Alternatively, you can use the local cups configuration environment on your Mac, if enabled (see help or various information pages online on how to enable this service). On the url field in your web browser type:
http://127.0.0.1:631. Now you see the management interface to cups. Here you can add, remove and modify printers as you like. The interface is quite intuitive.

You might want to set double-sided printing on by default, to save paper. Click on the Administration menu and choose “Set Default Options”. From there clicking on “General”, you can choose to turn on “Two-Sided”. By clicking “Set Default options” the setting is saved for all future sessions.

The printserver supports the Internet printing protocol (IPP; also known as CUPS). To add a printer, make sure you select IPP as the protocol, and
printserver.strw.leidenuniv.nl. The queue on the server is under the

Next you can select the manufacturer and printer model, or use a generic postscript printer driver. See the list of available printers for details.
Also make sure to use A4 paper in stead of American letter format.
Note that it is currently not possible to automatically search for printers; you will have to specify the name of the server and the queue manually.
If your laptop is running its own local CUPS daemon, you can follow the instructions for CUPS given under Mac OS above.
Windows should be able to use this method as well ( but not always? does anyone know which driver or windows component is necessary? )
In the Add printer wizard, select the option “Connect to a printer on the internet”. Windows will first try to find the printer, which is unfortunately not possible in our setup. When offered to enter the printer's address manually, click “next” and in the URL window fill in (for sterrewacht):

Of course this works for any of our printer names, so fill in your printer of choice here. A list of available printers is available, along with their make and model, for selecting the right driver. Also make sure to use A4 paper in stead of American letter format.
