I have an odd situation. I have several HP Laserjet 400 on our network. For some reason at one site, one of the printers will not keep it's IP address. The IP address is static and the people printing to it are using Windows 7.
I have set up the IP address and was able to print from the printer; access the printer through the web page, etc. About a month ago, this printer stopped working. It would print for a while then nothing would print. Unable to ping the IP address, etc. turned off and back on; unplugged network cable, replaced cable; moved printer to another port. I figured it was a printer issue, right; (this printer was brand new). I replaced the printer with another brand new printer and within 2 days it was doing the same thing. I changed the IP address manually and could connect via the web page. I had people print and it worked for 2 days. On both printers, the printer would print fine first thing in the morning, but after the first couple of documents, the problem occurs again.
I use a program wherein I can see the status of each IP address in the company. The status of the IP address is Transient.
If anyone has any idea what may be going on, I would really appreciate your help.
