Laserjet P2015 - can I add a network card?

Typically, unless you buy the really high end HP Laserjet printers there aren't slots to add cards such as what you're referring to.  What I would do in your case for cost effectivness and accomplishing the same goal is to attach the printer to an external JetDirect.  It will provide the same functionality and will likely be cheaper.  I've provided a link below to a model that is on the CDW site.  The other nice thing is that the external JetDirect can work via a hardwire connection or wireless b/g.  The other plus is that if the P2015 printer dies you can easily move the JetDirect to any printer that has a USB connection.  :-)  Hope this helps.

USB printer sever will do the trick.

Like the one from netgear

brisquet - would this be the kind of thing to look at?

I'm hesitant to use a USB print server as I've had mixed luck with those in the past - I just need to be able to assign it an IP address and go to the remote PCs, add local printer, TCP/IP port, etc.  If I need to pay $130 for a formatter board to get a network jack, I'm ok with that.

Thanks!

Yes, that would be the correct part.  HP does have a print server for this particular model here:  http://partsurfer.hp.com/Search.aspx?type=PROD&SearchText=CB366A

I am guessing at the model # of your printer here but the print server is compatible with all P2015's.  I would go with the print server in the off chance the formatter would not be compatible, but I don't see why it wouldn't work.

I would advise the External Jetdirect route, USB ones do work but are less reliable.
