Lexmark X644e 用户指南

The following information applies to  protection.

•

You can set both read/write and write s for a resource. If both s are set, the 
read/write  has precedence over the write .

•

If you attempt to -protect a non-existing resource, the PJL interpreter will 
return a warning (CODE = 25001).

•

If a resource has already been  protected, the resource must be “unlocked” 
before you can specify a different  for that resource.

•

Several restrictions with s apply to flash due to the nature of the technology:

– You can create/change s for the whole flash multiple times, but each change 

uses up free space in the flash that can only be recovered by reformatting 
the whole flash.

– You can create s for individual resources on the flash only once. You can 

also delete this  once. If this is done, you must recreate the resource before 
using the  feature again.

Use the DEFAULT command to set a  on the entire flash or disk or on an individual 
macro or font in flash.

LRWLOCK with DEFAULT specified locks a file or device for reading and writing. 
LWLOCK with DEFAULT specified locks a file or device for writing only.

@PJL DEFAULT LRESOURCE:"device:filename.filetype" LRWLOCK=""[<CR>]<LF>

@PJL DEFAULT LRESOURCE:"device:filename.filetype" LWLOCK=""[<CR>]<LF>

The filename used depends on whether you wish to put a  on a font or a macro.

The filename for a font is a five digit ID from the print directory page (add zeros to the 
left of the ID to fill the five digits) followed by a three digit instance number. The first 
time a font is downloaded after a flash has been formatted, the instance number is 0.
