Printing on the 4th floor from Mac OS X
2008-11-26
These are instructions for setting up computers running Mac OS X 10.5 (Leopard) to print to the IWI printer on the 4th floor of the Bernoulliborg. The printer is a Kyocera FS-3900DN which for entirely mysterious, to me, reasons is available in the Netherlands as Océ WP35.
Download and install the drivers. You need the file Kyocera OS X 1045 v1.0a.mpkg.zip. Then, in the Mac´s System Preferences select the panel Print & Fax. Click on the + button. In the window that appears click on Default, select Oce_pr2 from the list of printers and press Add. In the next dialog press Continue. Succes!
Update Feb. 16 2010: There is a problem with the Kyocera drivers under Mac OS X 10.6 (Snow Leopard). There are two possible solutions. The first is to use the Kyocera 3800 drivers that come with 10.6. I don´t run 10.6 so I only have second-hand knowledge that this actually works. A second possible solution for which I don´t even have second-hand knowledge that it works is to download and run the OSX 10.6 Permissions Fix program available here from Kyocera. Detailed instructions are also available.
Update Jun. 11 2010: I now run Snow Leopard, and I can verify that the official Kyocera driver for FS-3900DN together with the permissions fix work perfectly. Furthermore, I have now changed the way I setup the printer so that I can print also through the wireless network (RuG-FN2). For this, instead of going to the Default pane of the Add Printer window, go to the IP pane. In Protocol choose Internet Printing Protocol (IPP), in Address fill in 129.125.68.42, and in Queue fill in ipp/FWN-5161-0400-OCEWP35. You can also change the name to something more recognizable. Finally, you have to manually choose the printer driver.

A handy bookmarklet
2008-11-20
At RuG we have access to several academic journals. From inside the university network this access is transparent. When outside I must first authenticate through a proxy server. The latter is sometimes inconvenient. For example if I'm at home and find a paper through Google, then in order to access the PDF I should go to the RuG journals list and search again. Although this doesn't take long it is somewhat inconvenient.
Somewhat more convenient is the following. If the paper is at the URL
http://www.iop.org/EJ/abstract/0951-7715/21/6/014/
then I can obtain full access to it by adding .proxy-ub.rug.nl after the hostname. The final URL is
http://www.iop.org.proxy-ub.rug.nl/EJ/abstract/0951-7715/21/6/014/
But what if the browser could help us add the (not easy to remember) .proxy-ub.rug.nl to the URL faster? This is possible with the following Javascript.
orig=document.location.href.toString();
parts=orig.split('/');
parts[2]+='.proxy-ub.rug.nl';
document.location.href=parts.join('/');
For maximum convenience I have installed this as a bookmarklet in Safari. Whenever I visit the webpage of a paper, I click on the bookmarklet and the magic phrase is added to the URL. After that I authenticate with the proxy server and I am redirected back to the paper webpage with full access rights. You can do the same by dragging the following link to your bookmarks bar or by saving it to your bookmarks.
Disclaimer: I hope that this works in Firefox and other browsers but I have never tested it.
