Hi Reliance, 

I'm traveling, and away from my printers so I can't confirm this, but I THINK the easiest way to do it is to open the HP Device Manager (in menu under system); if that's not there then install hplip-gui and set up your printer with it. One of the options when you select your printer in the GUI is to open its webpage - you can also get there by opening a browser, logging into your router to find its IP address, and then entering that in the bar. The printer's webpage should have the option to upgrade firmware, somewhere though I don't remember where. 

If I'm wrong about that, the way I'd do it is to open my Win10 Virtualbox and then use the windows-based tool to update the printer. Now, setting up a vbox is kind of a time-consuming way to do a printer upgrade, but it has other uses. If you've never used virtualbox, it's way easier than you might think - just install, add yourself to the vbox group, download WIn10 from the Microsoft website, run the wizard in vbox to setup the guest, open settings for the guest and in storage tab add the iso you downloaded for Win10, in network set bridged adapter, and in system/acceleration choose hyper-v from the dropdown. Launch the VM and follow the install process for Win10 (the time-consuming part) just as you would on a real computer; it'll let you install without product key though some features (especially customiation) will be disabled, and after it boots for the first time just leave it running awhile in background while it sorts itself out - otherwise you'll think it's super sluggish. 

You should be able to add the printer if networked, but with usb you'll need to install the extension pack for vbox host. Get it from Oracle's website and add it through preferences in one of the menus in the vbox interface. And you'll need to install the guest additions for Win10 - get it through the devices menu on the running virtual machine. (The guest additions also allow you to access documents on your host machine from the Win10 guest.) This has been a high-level overview; ping back if you need the step-by-step version.

Hello,

I'm using a HP Laserjet 1536 dnf MFP on my LAN.

According to  Faxploit not only the inkjet family is affected but all fax machines.

Is a solution planned for the Laserjet family?
