5.3.7 SAVING FORMAT FILES COMMANDS
The printer has the capability to store a format file in RAM without processing it. Later, this
file can be accessed repeatedly at very high speeds, because access is now a direct
memory fetch. The printer will retain these format files after the removal of power. The
printer can be configured through software dip switch 2 (see section 5.3) to automatically
process the file at power up. The printer treats these files exactly as if they were sent
through the communication port.
^A ^D Command
XX 54 Send Saved Format File to Serial Port: ^A selects which one (1-8).
XX 58 Process Saved Format: ^A selects which user entered format (1-8) is to be
printed.
XX 59 Save Format File: ^A selects which slot (1-8) in which the user entered format is
to be placed. The format file must be terminated by an ESC (1B hex) character.
66 66 Initialize Storage Area for Format Files: Used when format files are to be
stored into Ram. This command must be issued before saving format files or when
saved format files need to be changed. There is no way to erase or change one
data stream, they must all be initialized. A ^A66 must precede this command.
USAGE:
Before sending the first format file, the RAM must be initiated by sending ^A66^D66
5
.
This command sequence reserves an area of memory for format storage. When this
command is issued, all previously saved format files will be erased. Therefore, it also
works as a memory clear operation. Only use this command before sending the first file.
Next send the ^A1^D59
5
command sequence. This indicates to the printer that file #1 of a
possible 8 is being sent to the printer. After this command, follows the format file.
The format file must be terminated with an escape character (1B hex) so that the printer
knows that the complete file has been sent down. The printer will not accept an ASCII
representation of the escape character.
To access the stored file, serially send ^A1^D58
5
, where ^A1 indicates the number of the
file that is accessed. The printer will now process the stored file.
All proceeding files sent to the printer to be saved also receive the ^AX^D59 command,
where X denotes the number of the file. Be sure that the ^A66^D66 command is not sent
again. This will erase all stored files. These files can also be accessed through the
^AX^D58 command, where X denotes the number of the file to be processed.
It is important to note that the saved format file mode works very well with variable text.
Configure the format file with all the positioning data, header information and fixed text.
Terminate the file with an escape character. Select the saved format and send the variable
data as normal. It may be the difference between sending a few lines of data versus the
entire format! Access is very fast.
To list a file that has previously been sent to the printer, use the ^AX^D54 command,
where ^AX denotes the file to be read. The printer will send the file to the serial port.
Sample files: File #1 initiates the save format file memory and downloads saved format file
#1. File #1 includes all the fixed data on the tag. File #2 is the file that initiates processing
of file #1 and includes all variable data for the format. File #2 also prints the tag. File #3
shows how a second saved format would look if the entire format was in one file.
NOTE: <ESC> = 1B hex or ESC character
