I have a wireless HP printer: HP LaserJet 200 colorMFP M276nw. It is connected wirelesslly to my home network. When I first installed it, the performance was very, very good. Any time I clicked "Print", the printer would respond immediately and within a couple of seconds the first page was being printed. Now suddenly for no apparent reason, print jobs have started taking 1-2 full minutes before the printer starts responding (meaning it just sits there as if nothing has happened, and then after a couple of minutes, it suddenly comes to life).
I cannot think of any changes I have made which would have caused this behavior, although it is possible that someone may have inadvertently made a configuration change on the printer without realizing it. There have been no changes to the router whatsoever. The router is an "all-in-one" modem/wireless router combo unit from Comcast.
Can anyone help me troubleshoot this?
