"Wireless print servers" tend to have a lot of issues, as you are typically using a TCP/IP network connection to connect to a device the driver expects to be on a USB port. OTOH, if you get a printer with a built-in ethernet port and have a wireless network connection to it, neither the printer or the computer will know or care about the wireless link; the only difference is a possibly slightly slower data transfer speed to the printer, which may or may not have any effect on print speed.
Thanks for the reminder of this. The Apple Airport Express has a USB 2.0 port on it and handles printing pretty well (via Bonjour), except that the utility hasn't worked for me on other printers (haven't tried it on the ipf5000 yet). Your suggestion of wireless via the ethernet port on the printer may be a better solution (the iPF5000 is ethernet equipped). I've never networked in this way, but have read something of it (obviously, I'm no network master). Wireless print servers (HP) have been a bit funky for me.
The Airport Express also has an ethernet port but I've not read that it can be used to network a printer (it's typically used to connect to a modem). A wireless router added to the network at the printer end may be needed, I guess. I need to dig around and learn more about the network requirements if I want to avoid running a Cat 5 cable the long and inconvenient run to the printer.
Currently, I'm simply transferring my finished files to a laptop and printing from that until I resolve this network issue. I'm remodeling a print work area and all of this is being taken into consideration.
