Cups-PDF on Fedora Core 3

I discovered Cups PDF today, it is a 'virtual printer' which allows you to create PDF documents by printing which can then be shared throughout the network, in much the same way as Acrobat does on Windows. This is something I'd tried to achieve before, although last time I was trying to use a shell script I found on the internet combined with a Samba share and it never worked. I downloaded the 'output to home directory' version of the RPM since I ultimately wanted to allow users to collect the results of their printed output themselves. The RPM installation was unproblematic, though there were a few spurious 'user not found' warnings, and I then tried to follow the advice of various howtos on the Internet - basically loadup up the Gnome printer configuration utility, add a new 'local printer' and then select the 'virtual pdf' from the list. Only there was no 'virtual pdf' in the list. I checked and double checked I'd done everything, and I even followed along with the manual install instructions to check the RPM had put files in all the right places, but no option was appearing in the printer utility. I was beginning to suspect this was because the Red Hat printer config utility was different from the Gnome one. After failing to find help through Google I decided to search my fedora-user archives in Gmail and the second thread I found led me to the solution: use the built in Cups configuration utility, which is by default available through a web browser on http://localhost:631 if cupsd is running. Here I clicked on the option to add a printer, put in a name and a description on the next screen along with 'localhost' for location and on the screen after that was a drop down list for 'Device' with 'Virtual Printer (PDF Printer)' near the bottom. Selected, saved, and tried to print through Firefox straight away - the document is created in a folder 'cups-pdf' in my home directory! Now to try it at work...
