Protection - Lexmark X644E Technical Reference Manual

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 3-52.
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.

renamed, or updated and a device cannot be formatted or specified as a download

ensures that data cannot be read from the file or device.
