HP LaserJet 4200 series printers include an embedded Web server with a variety of options. One of the options is NTP, or network time protocol, configuration. The HP printer's NTP client automatically sends out requests to obtain the current time from an authoritative NTP server, which ensures the time on the printer is correct. You can configure the frequency of the NTP requests coming from the HP 4200 as well as the port it uses.
Type the IP address for your HP 4200 into your Web browser's address bar and press "Enter." If you don't know the printer's IP address, print a configuration page using your printer's console and locate the IP address printed on the page. Consult your printer's manual for instructions.
Click the "Settings" tab at the top of the Web page.
Click "Time Services" in the menu on the left side of the page.
Type the NTP server you want the HP 4200 to use into the "Network Time Server Address" box.
Type the interval between NTP requests in hours into the "Synchronize Time with Server Every" box.
Type the local NTP port the HP 4200 will use into the "Local Port to Receive Time from Server" box.
Update the time from the NTP server immediately by clicking "Get Time."
Save the settings by clicking "Apply."
