Scenario: You have a new HP Color LaserJet Pro MFP 4302. It has been powered up and assigned (manually or by DHCP) an IP address which already has a DNS address associated with it. After finding the label with the initial admin password you try and access the Embedded Web Server (EWS) via your web browser. You use the DNS address for this.
What you get after a couple of seconds is a HTTP 403 error.
Try accessing the page using the IP address – it should work. The problem seems to be that if the printer thinks its DNS name is different from the actual address it breaks the EWS.
In this particular case, it was fixed by going to Network→Network Settings→Identification and changing the Host Name to be the same as in the DNS server. Then (after some refreshing of pages and re-logging in) you can use the DNS address to access the EWS as expected.
Windows driver – IJ Network tool does allow you to input IP address eventually (Mac version does not). Conveniently our print server was on the same subnet as the printer, so it found it straight away. Driver can be installed on Server 2012 and shared, but cannot be shared as a LPD queue (as Canon don’t use a standard IP port).
Printer does function as an IPP printer, and LPD (if enabled).
On the Mac, use the IP address of the printer – it doesn’t communicate properly with the DNS name.
If the HP Universal print driver cannot automatically retrieve a printer configuration (say SNMP is blocked on the network or disabled on the device) it defaults to monochrome printing (UPD version 5.0 and newer). This can also lead to long pauses while trying to open the printer properties, as it presumably times out while trying to retrieve the data. On the Device Settings tab, click Device Type: Auto Detect to display the drop-down list and then select Color (and also check the duplex setting).
