The description field for fonts comes from the font header. The description field for 
macros or symbol sets is blank unless the description field in the file header is set by 
the PJL LRESOURCE command. See “Printer Unique LRESOURCE Variables” on 
page 3-52.

The description for macros or symbol sets can be set only once for files stored in flash 
memory. The description can be set any number of times for macros or symbol sets 
stored on a disk. The limitation for flash files is due to flash technology. See the  
“LDESCRIPTION” variable in “Table 3-9: Printer Unique LRESOURCE Variables” on 
page 3-53 for more information.

You can  protect either the entire flash memory or disk, or files stored on the flash 
memory or disk.

There are two levels of  protection:

Read/Write

has been appropriately specified (applies only to actual file data).

Write

Ensures that data cannot be changed on a file or device unless the  has been 
appropriately specified. A Read/Write  takes precedence over a Write .

Each file or device can have a separate . Write s ensure that files cannot be deleted, 
renamed, or updated and a device cannot be formatted or specified as a download 
target. Read/Write  protection provides the same protection as Write, but additionally 
ensures that data cannot be read from the file or device.
