Q: enable Laserjet 5000N to print from MacPro

Have you downloaded the drives for Apple Soffware Update? See:

http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03413323

aboutthe only I can tell you is that this printer uses DHCP.. and yes, there are newer drivers for it. the website mentions a jet direct wireless card and that you have to put the printer in "Ad-hoc" mode, whatever that is....I think the crystal ball's starting to go dark...maybe reset printing system...add network printer...maybe try "Gutenprint" or "Gimp Print".??...doesn't appear to be listed as Yosemite-friendly...okay, I think I got it

here's how to do a cold reset on the printer.. turn it off. hold "Go" key, turn on printer, keep holding "Go" key until you see "COLD RESET:"

release the "GO" key, watch for INITIALIZING, then restoring Factory Settings...then OFFLINE..press "Go" again to put it online. see if you can get it

to spit out a configuration page..press menu until you see info menu...then item...then Print configuration, then select to print page....

go to print and fax preferences..go to existing icon of your LaserJet priner and click "Minus", then click plus, then go to add printer, then select IP

button at top. Under "Protocol"  choose HP Jetdirect-Socket is chosen. Under address, type in  your printer's address. Make sure "Print using" is set to

HP LaserJet 5000. you may have to turn on Internet Sharing on the Mac, possibly/

I've given it a try, anways

Such a Printer is capable of being a device on your Network. You connect it with an Ethernet cable to your Router, not to your Mac.

Connected to the Router, it can get a valid local IP Address and become visible to you so you will see it in the Add-a-Printer box.

My router is part of the modem that Comcast installed. My Mac has an AirPort card and needs no other router. I can not connect another router to my system, since the modem is far from my office and my printer. There's no way I can run an RJ-45 cable from the modem/router to my printer.

If the Printer is near your computer, it should also be able to receive the same signal your computer gets over Wi-Fi. But it needs to ahem an IP Address set up and the network-name and password entered. Typically this is done on the control panel of the Printer itself. Once it has this information, it can participate as a wireless Printer on your network.

"ahem an IP Address" above is supposed to read "Obtain an IP Address"

Unfortunately, this is not a printer with wifi capabilities (built 1998), and the only way it will connect to the computer is over a "network", i.e. not directly to computer via ethernet cable. It has an IP address, however.

what cables does it have? you may be able to connect with USB.

If not, there is a somewhat complicated way you can Share your Wi-Fi connection out over Ethernet to connect to other devices. This implements a software Router in your Mac.

It has a 10Base-T, 10Base-2 and a LocalTalk connection on its HP JetDirect internal print server. I think the only one I can use is the 10Base-T. No USB.

How would I implement a software router in my Mac? I tried to connect my Mac to an auxilliary router, but it didn't work.

System preferences > Sharing > Internet Sharing

share your current Wi-Fi connection of your computer out over Ethernet.

The software Router by default establishes its network with the Router Address at 192.168.2.1, and a Subnet mask of 255.255.255.0, so attached devices need to ask for an address via DHCP, or have an address in that range, such as 192.168.2.250.

If you examine the interface using

system preferences > Network > Ethernet ...

... it will always have a self-assigned IP address (which keeps it from being used for other traffic). This is normal.
