HP's LaserJet Firmware Update Solves Unauthorized Printer Access Issue
HP has built a firmware update to mitigate this issue and is communicating this proactively to customers and partners. No customer has reported unauthorized access to HP. HP reiterates its recommendation to follow best practices for securing devices by placing printers behind a firewall and, where possible, disabling remote firmware upload on exposed printers.
The firmware update can be found at www.hp.com/support and selecting Drivers. Additional printer security information is available at www.hp.com/go/secureprinting.
So, there you have it. All better. Well, after you download that update.
