Wired and Wireless Printing

I'm not even sure where to put this.

I have an HP 8600 Premium e All in one. This printer can be printed to wirelessly OR wired. I did not know this when I bought it. For a top of the line MFP, and with the prevalence of both wired and wireless networks coexisting, this is just mind boggling that there is no out of the box solution that comes with the 8600.

That being said, I have iPads, iPhones that need to print wirelessly and PC's that need to print wired.
I am running a Windows SBS 2008 network.

If I connect the 8600 to my wireless network, the iOS devices can print with no problems but the PC's cannot. If connect the 8600 via cable to the network, the PC's can print and the iOS devices cannot.

Now the 8600 does allow for the wireless setup to run on a wired PC. The problem is that the wireless network will not be the same as the wired network as the wireless router/access point has to serve IP addresses to all devices connecting to it wirelessly. So they will always be on separate networks due to the fact that my SBS server serves IP addresses to all wired devices and 2 DHCP servers cannot exist on the same Windows network.

My fix, so I thought, was to pick up a Airport Express base station, thinking that I would connect the printer wired or wirelessly to that and the iOS devices would be able to see it.

Didn't happen.

My goal is to have my iPads, iPhones and PC's print to the 8600 printer.

I'm open to anything at this point.

Most MFDs with a built-in print server lack an internal routing facility, so only one network interface can be active.

Assuming that the printer has a fixed IP, set the router as the printer's gateway, and allow a route to the printer's IP from the other network.

main network
default gateway (sbs server or router)
set route for>ap/router

default gateway

You may need to disable SNMP and bidirectional communication in the printer properties ports tab.
Assuming you have a wireless access point (AP), jack the printer and PCs into it and the iOS and any other wireless devices via WiFi.

Make sure that the WiFi on the AP is not using a different subnet as the wired side of the AP.  Many APs only support a single subnet between the LAN copper ports and the WiFi but a some support separate subnets (such as a guest WiFi that usually only has access to the WAN port and beyond).

This sounds like a firewall/router problem. First get a laptop and connect it to the wireless. Then try and ping one of desktops on the wired network. If you cant ping then you have a firewall/router problem.

So your wireless network is separate from your wired network?

You stated the printer can run both wired and wireless.  So connect it to both networks, and it should obtain an IP for both networks allowing all devices to print.

Printers work best wired in my opinion.

So that being the case, look for an app that will permit your iPhone to print on any printer. Here is an example.

Just put the wireless AP on the same network as the wired LAN and disable the AP's internal DHCP server. Let your SBS server manage all DHCP requests, also those for the WLAN. Then you can either connect the printer wired or wirelessly to your network and printing will work for all devices, whether they use wireless or wired.

I appreciate all of the comments but it's not a router/firewall problem. It's by design.

The wireless and wired networks cannot be on the same network.

The reason for this:

The wireless access point / router needs to serve IP addresses to wirelessly attached devices which makes the wireless access point / router a DHCP server.
The SBS server on the wired network needs to serve IP addresses to wired attached devices which makes the SBS server a DHCP server.

You cannot have 2 DHCP Servers on the same network yet both are needed in this scenario.

Now you can access resources from the wireless to the wired network via routing on the wireless access point / router, but not printing.

Unless there is a way through a RADIUS setup of some sort.

I like your thoughts on this but my setup doesn't allow for it. Though I could add another AP.
Do you have an AP in mind that will allow the airprint function? Or is it simpler than that? My Apple printing understanding is limited.

What are the IP ranges of your networks?

If the wired and wireless are separate networks.  You should be able to hook the printer up to each at the same time.  The wired NIC of the printer will obtain an address from the SBS server.  The wireless NIC will obtain an IP from the Wireless Routers DHCP.

It would be the same as having a computer or server with 2 NICs on separate networks.

As I recall on some of those printers, the wireless is disabled when you plug in an ethernet cable.  

Once the printer is connected with ethernet to your network then any wireless device that is capable should be able to connect to the network with wireless and, hence, to the printer.

Of course, you have to have a wireless segment in your network like a wireless router or access point....

Thanks Remmett70, but HP explicitly denies that functionality. Only one connection can be active. If you connect a cable to the printer, the printer automatically shuts down wireless.

Fmarshall - that's provided they are on the same net.

For me, it's a security issue. I like to keep my wireless networks separate from my wired networks except through very specific routing.

This just got a lot more complicated than I wanted it do.
In my point of view there shouldn't be any need for a special "airprint" function  to be able to print. But then I don't have much to do with MAC gadgets.
I think that the air things like airplay and airprint work off of the broadcast domain and will not work on a routed network.

You should be able to set the wireless AP to do 'DHCP Relay' and point it at you SBS box for the DHCP server.  That way you can bring the two networks back down to one and have everything accessible wired or wifi.
