When I go thru the installation wizard I don't find a driver for the P513w on the list. So I've been through all 7 (like 1100) that are on the list but none of them work. Anyone got any ideas?
I found this: http://www.dell.com/support/drivers/us/en/19/DriverDetails?driverId=R247660&fileId=2731129060 Wonderful! An Ubuntu installer for your exact printer. However, depending on your Ubuntu version, it's too old to install correctly. Notice it was built in 2009. As an experiment, I installed it on a print server I have running 10.04. In this case, it actually pays to be old!
I copied the .ppd files and zipped them and here is a link to my Dropbox public folder: https://dl.dropbox.com/u/58267392/Dell.zip
Copy the file to your desktop. Right-click it and select Extract Here. Open a terminal and do:
Now add your printer and select the ppd file at /usr/share/ppd/Dell/dlP513w.ppd.
I found additional guidance here: http://ftp.dell.com/Printer/R247803_Readme.txt
Good luck and let us know your success!
