Thanks! I needed a little comic relief. This has been a little grinding since the printer problem is so sporadic. OK. The printer problem is back this pm, even though nothing was done. Both the MBP and MP quit seeing the HP printer. The Macs wifi to the D-Link and the printers plug into the D-Link.
The printer shows via its config printout that it has address 192.168.0.110, I just pinged that address from my MP using terminal and got a good response. I logged onto the D-Link router and it shows the HP printer at 110. Based on previous experience, if I do nothing, either tonight or tomorrow it'll print again. How do I check a DNS caching problem?
If the computer is talking to the D-Link router (192.168.0.1) and wants to send a print job to 192.168.0.110, doesn't that eliminate the need for DNS?
Thanks for your time.

If the Macs and the Printer are on the same subnet (have addresses in about the same range, which these do) the Router does not intervene, it only Bridges (passes the packets) wireless to wired without changing anything.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

The D-Link says the MP is 192.168.0.102 and the MBP is 101. The Brother printer is 103 and the HP is 110. Both printers are static IP.
Just for completeness, the D-Link goes into a Verizon router/modem. I've turned off the wireless function on the Verizon unit. There is one DirectTV cable going into the Verizon. Everything else, ipads, iphones, Netflix boxes and Samsung TV are wireless into the D-Link. For a long time this used to work just fine...
Earlier, the Brother printed and the HP did not. Now neither printer is seen by the MP.

Arrrgghhh!! When I tried to print to the Brother, the message was printer not connected. So I deleted the file from the que, and closed the print box. Just now, five minutes later, the Brother started up on its own and printed the page! What??

Is this an intermittantly defective D-Link? I'm going to go back to just the Verizon unit, take the D-Link out of the loop, and see if this goes away. Tomorrow that is. Thanks for the help.

If you are passing out DHCP Address in the same range, you may occasionally give your Mac the same IP Address as the printer. The manual IP Addresses and the automatic TP Addresses should be a little different.
For example, my printer is at 192.168.0.17 manually
The first IP Address assigned automatically is 192.168.0.101Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

I don't think this is a DCHP issue. Printers drop in and out within a day, and the computers are never turned off. Plus, when I make the printers static I tell the router. I have moved the printers back to the Verizon router/modem, restarted the Verizon wireless, moved the computers over to the V wireless, installed the printers with their new addresses and Bingo! they both showed up on both computers as available to use! I'll try this and see if the printers disappear.
There are discussions elsewhere about the DIR-615 router losing connections, but they seemed to be wireless problems. Mine have all been through the wired ports.
