Update to the foregoing: I have now moved the printer so it's right next to the router and is showing 5 bars. However, it's still very intermittent. Initially it would respond to a ping, but is now reporting "host down". So the problem doesn't seem to be related to signal strength after all. One interesting point: when it was failed to print initially, I deleted it from the list of printers and then re-added it. It worked once after this and then went offline again.

In case you had placed the printer right next to the router I would highly recommend you to muve the device a bit and place it no closer than 1.8m (6 feet).. Plecing two wireless devices right next to each otehr may cause signal interfations.
Also try checking for any available firmware update for the router and check for any change, as well check for any available firmware updae for the printer:
I do believe the issue is still related to the router in any matter, considering the difference we did seen after enabling Multicasting.

OK, I've moved the printer so that it's no longer next to the router. It's now next to the Mac that I'm trying to print from. They're both connected to the same wireless router, and there are two bars showing on the printer's status display (i.e. not perfect, but should be adequate - the Mac next to it connects to the internet fine). If I ping the printer, I get a round trip time of around 2ms on average.
However, when I try to print, it claims to be offline.
I can't see why I should need to upgrade the firmware, because it worked perfectly adequately in the previous house. Please tell me what I can try next.

Hmmm. Deafening silence there. PLEASE can you help me?
Here's the latest situation. I have changed nothing in the settings of my printer since I moved house. The only thin I have changed on the router settings is to permit multicast. Both my Mac and my printer are connected to the same wireless router. There are no relays between them. The printer is showing two bars on the network status display.
When I ping the printer, I get a round trip time of around 0.04ms.
1) When I print a simple Word document, it initially claims that the printer is offline. However, after a considerable delay (anything from 5 minutes to 30 minutes), the document does eventually get printed.
2) When I try to scan anything, it usually tells me that it can't make connection to the scanner. Very occasionally it works.
3) Sometimes I can establish a connection to the embedded web server, sometimes I can't.
This is not a tolerable situation. If this continues, I will probably hurl the printer out of the window. Can you PLEASE tell me what I can do to make this thing work reliably?

I believe updating the firmware would be a good thing (as ShlomiL has stated previously). Here is an article that deals with maintaining a wirless connection (which includes updating of the firmware):

No joy. I've run the product update thing from the printer itself and installed the latest driver (which, looking at the date, was probably the one that was in use anyway) and I still can't talk to the printer. Right now I can ping it (average turnaround 0.05ms), but I can't open the web server. I'm willing to bet this will change at random later.

Just to be sure...did you do everything in the article (Power reset and Static IP assignement)? If not, please do so and let me know the outcome.

OK, I've changed the IP address to a static one, and it's still no better. In fact, it's worse, because I deleted the printer from the Mac control panel in order to avoid any confusion, and now it can't find the printer to add it back again. I can ping the printer's new address, though. Even though it seems a LOT slower than before. Please help. Because at this rate I will be forced to buy a separate printer for myself, and I'm afraid it won't be an HP one. In fact, I won't be buying any more HP printers ever.

Ok, now that you have a different issue I recommend checking out the following:
This should help you atleast get the printer installed again. Let me know what happens.

Printer definitely connected to the network (and I can ping it, as well as access the EWS). Router apparently supports Bonjour. When I went to add it via the control panel this time, it briefly appeared, then promptly vanished again.
