Description
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 3-44.
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 3-45 for more information.
Password Protection
You can password protect either the entire flash memory or disk, or files stored on the
flash memory or disk.
There are two levels of password protection:
Read/Write
Ensures that the file or device is protected against reading and writing unless the
password has been appropriately specified (applies only to actual file data).
Write
Ensures that data cannot be changed on a file or device unless the password
has been appropriately specified. A Read/Write password takes precedence
over a Write password.
Each file or device can have a separate password. Write passwords ensure that files
cannot be deleted, renamed, or updated and a device cannot be formatted or
specified as a download target. Read/Write password protection provides the same
protection as Write, but additionally ensures that data cannot be read from the file or
device.
