OVERVIEW HP Web Jetadmin provides several options for managing storage media in HP devices. Device lists display all storage media types and properties/contents. Hard disks can be initialized or securely erased using different levels of data overwrite. Fonts, forms, and macros can viewed, added, deleted, and remotely printed on devices. Print jobs that have been stored on the printer through the job retention feature of the printer driver (disk jobs) can be viewed, deleted, and remotely printed.

MEDIA Once the Media item has been selected from the View drop-down menu, a Storage Media column is visible that contains a list of all storage media installed on FIGURE 3 – STORAGE MEDIA PROPERTIES the device. If the Storage Device count is 1 or greater, the mouse-over tool tip displays a table of all the storage media on the device. The table contains the properties of the media such as Description and Size (see Figure 3).

The HP    Secure Erase feature will not impact data stored on: Flash-based non-volatile RAM that is used to store default printer settings, page counts, etc. A system RAM disk (if utilized) The flash-based system boot RAM Changing the erase mode (Secure Sanitizing Erase, Secure Fast Erase, or Non-secure Fast Erase) does not overwrite previously stored data on the disk, nor does it immediately perform a full Secure Storage Erase.

Erase Customer Data Secure Storage Erase has traditionally referred to an erase operation that performed one of three erase behaviors over the entirety of a physical disk. Newer devices offer a different type of secure erase method, Erase Customer Data. Instead of erasing physical storage devices, the Erase Customer Data operation acts on the logical notion of customer data. The user cannot select a physical disk and request an erase.

A File System Password is no longer required for the Erase Customer Data operation. Also, the File Erase Mode set under Configuration is only used for secure file erase of everyday temporary files. For storage erase, an erase mode is passed as a parameter to the erase method. Instead of the userselected storage devices, the storage erase method will always erase all "customer data." To invoke the service, a client with correct web credentials makes a call to Erase Customer Data passing a valid erase mode.

Initialize File System The Initialize File System command acts directly on the disk partitions to provide troubleshooting and diagnostic tools. The manipulation of disk partitions is similar to formatting a hard disk and does not provide sector level overwrites of the disk space previously assigned to the removed partitions. These erase commands are not recommended for securely removing customer data.

Figure 8 – Storage Repository Before fonts and macros can be installed on devices, they must be imported into the storage repository (see Figure 8). Upon import, the files are converted into fonts or macros that the printer will understand and accept. This step calls into the FontConversion.dll and ImageMagick.dll files that were inherited from Web Jetadmin 8.1. They can ensure that page commands are stripped out and macro definition files are added.

PCL Bitmap Fonts - *.LGP, *.USL, *.USP, *.R8L, *.R8P, *.L7L, *.L7P Macros: PostScript Macro - *.pfa, *.prn *.txt Bitmap Image - *.bmp Collections: - TrueType Collection file, *.ttc, contains a collection of TrueType Fonts in one packaged file. This file will be broken into its individual font files before it is sent to the FontConversion.dll for processing as FontConversion.dll cannot process collections on its own. If, during the file conversion process, there is no output from the .

The USB media drive will actually contain an “entities” directory in which resident fonts will exist as xxx.bin files where “xxx” is the name of the font. It is also possible to install non-resident fonts with WJA on a USB drive that already contains resident fonts if it shows up as a separate drive in the Media column. The fonts/macros installed will be placed in their respective directories on the USB drive (eg.
