HP Designjet Printer Series Security Settings 3.17 User sessions This feature allows you to set a timeout so that open sessions to ePrint&Share from the printer front panel are automatically closed if they are not used. 3.18 Disable internet connection Disable the direct connection of the printer to the internet. This option would also prevent the printer from automatically performing firmware upgrades. 3.19 Printer Access control For some printers, when setting an Embedded Web Server admin password you are also preventing access to certain front panel features. The features protected in the front panel are: • Network connectivity & Internet Connectivity • Control firmware upgrades • Reset factory defaults • External hard disk connection • Security If a user loses the admin password, it is not possible to reset it so the printer would be locked. There is a service menu option to reset the admin password. 3.20 External hard disk (EHD) Some printers allow the connection of an external hard disk. Any HP Designjet printer with an internal hard disk uses it for four main purposes: • Store the printer's firmware & resources (media profiles, demo plots, diagnostic plots). • Virtual memory for job processing. • Job storage/queue • Storage for printer's accounting data. The HP Designjet External Hard Disk was designed to fulfill one specific use for those security conscious customers that want to preserve the confidentiality of the jobs being printed in their HP Designjet printers. How the system works 1. Connect the External Hard Disk (EHD) into the printer's USB host port. 23
