HP Laserjet CP1525nw and AirPrint

If you want to check Bonjour is working properly from your iPad's perspective on the network, there is an iPad/iPhone app available called "Discovery - Bonjour Browser" by Tidesoft. It's not free, unfortunately, but I can't see an alternative for iOS.

If you use it (or some other non-iPad based Bonjour tool for PC/Mac) then you're looking for an advertised IPP service (Internet Printing Protocol) from your HP printer. If you drill down into that, look at the capabilities list in the PDL record. It needs to include "image/urf". There should also be a URF record.

If none of that made any sense, I can give you a more step-by step run-through. The app is pretty automatic and straightforward to use, though.

If you do see what I described on your iPad then AirPrint should work, and I'm at a loss to explain it!

It certainly looks that way. The list of services should appear within a few seconds.

I guess it's up to the network people to tell you where to go from here. But as I said earlier, Bonjour is essential to AirPrint. If the iPad doesn't see that specific IPP service then your printer won't appear on the list.

Good luck!

If you've got the latest firmware (and it sounds like you do), and Bonjour Browsers shows absolutely nothing, it sounds like either your router is blocking Bonjour discovery (assuming your CP1525NW is on the same wireless network as your iPad). If they are not on the same Wireless network, they both must at least be on the same subnet for Bonjour to work.

I had the same issue - I purchased a CP1525nw because I needed a new printer, and I got this one because it is Mac OS compatible, wireless, and had Airprint compatibility. I also did not see the printer from my iPhone. I simply installed the HP firmware update utility and now everything works.

Same issue here, only with intermittant errors. I found that pinging the IOS device from my main computer makes it work, as long as the ping is active.

Stop the ping, and printer discovery fails.

HP support told me they only support the printer, not devicing connecting to it.

So this sounds like a router issue. Not sure it makes sense, but with the pings going, the router is allowing Bonjour (which uses mulitcast DNS) to work. Stop the pings and the router stops letting the Bonjour packets through. We have seen quite a few router specific issues. Which router do you have, and how is your wireless network configured?

Actiontec MI424WR. It's the router that Verizon issued to Fios users.

Wireless network is WPA secured, 255.255.255.0 mask and 192.168.1.1 as the gateway.

Typically have a couple windows machines on, a couple iphones, and an ipad.

OK, I think we have an Actiontec in our lab. I'll give it a try and let you know what I find.

Thanks, let me know if you need more network details.

I'll be giving it a try over the break. And you're not the only one reporting issues with the Actiontec routers. If I come up with something, I'll post back, likewise if I need more information. And thanks for helping work through these issues.

I have the same printer and the same errors. Quick question, does my printer need to be on the wireless network to operate AirPrint. It's currently connected to my wired network and I'm able to see the printer from my iPad with the printer's IP address. The printer has the latest firmware as of 12/2/2010.

Ok, answered the wireless question myself, configured it for my wireless network and still "no printers found"

Paul-

I understand that printer will work either wireless or by connecting to the router via Ethernet. It is the USB connection that does not work.

Unless there is a newer firmware update for the printer, the only remaining suspect is the WiFi router. You can set the printer up as an Ad Hoc network to bypass the router. Your iOS device should be able to connect to the printer's WiFi directly, and then should be able to find it when printing.
