Windows Server 2008 (32 bit/64 bit) , Windows 7 (32 bit/64 bit) , Windows Server 2008 R2
or Windows 8 (32 bit/64 bit)

3. HOW TO CONNECT PRINTER TO PC

3.1 Connection with serial interface (RS-232C)

The communication conditions must be set to the factory default values, as follows:

Communication speed: 9600 bps
Data length: 8 bits
Parity: None
Stop bit: 1 bit

RS-232C

(1) Select “Change blocks” from the “TOOL” menu, and set the number of memory blocks to be used for

storing the TrueType font files.

The dialog box to be displayed differs depending on the selected printer.

(1.1) LE840/LE850 series (1 block = 128K bytes)

The LE840/LE850 has a total of 24 blo cks of expansion memory. Since this memory is shared by
TrueType font files, writable characters, BASIC files, and PC save commands, it is necessary to set
the number of memory blocks to be use d for TrueType font files and writa ble characters, and
BASIC files by using this command. The remaining number of memory blocks is used for P C save
commands.

After the number of memory blocks is set by this command, all data in th e expansion memory,
including writable character data, BASIC files and PC save commands, is initialized.

6. INTERNAL SPECIFICATIONS FOR LE840/LE850

This section describes the commands specifically used for the communication between the tool and the
printer.

The TrueType fonts to be stored in the printer must have a license. To
obtain the licensed TrueType fonts:

• Purchase commercially available TrueType fonts.

• Obtain the license from the publisher.

6.1 TrueType Font Memory Block Command

Function Sets the nu mber of memory blocks for the True Type font da ta, writable characters,

BASIC files, and PC save commands to be downloaded to the printer.

Format {XF;aa,bb,cc|}

Term aa: No. of memory blocks for TrueType fonts

bb: No. of memory blocks for the writable characters

cc: No. of memory blocks for the BASIC files

00 to 24

00 to 24

00 to 14

Explanation • A total of 2 4 blocks can be allo cated. These are allocated in the followin g order:

TrueType fonts, writable characters, BASIC files, and PC save commands.

• If the total number of blocks exceeds 24, the excess blocks are not allocated.

- 12 -

6.2 TrueType Font Data Loading Prepare Command

Function Requests the printer to make preparations for downloading the T rueType font data. If the

printer is printing at the time, the printer stops printing. When the serial interface is used, the
printer returns a status in response to the TrueType Font Data Loading Prepare Command,
when the printer is ready. At this time, the next comman d should not be sent until the
PC receives the status i ndicating that preparation is completed from the printer. If the
TrueType font data is d ownloaded to areas other than the memory blocks specified by the
TrueType Font Memory Block Com mand, the prin ter LED lights up in red indicating that an
error has occurred.

Format {LDT;aaaa,bb|}

Term aaaa: Address that the data is loaded (in hex.)

[00H] [00H] [00H] [00H] (00000000H) to [xxH] [xxH] [xxH] [xxH] (xxxxxxxxH) Since

the address where the TrueType font is loaded is CC0000H, [00H] [CCH]
[00H] [00H] is specified. However, the printer ignores this setting, and

bb: Size of data to be loaded (in hex.: in units of KB)

downloads the data to the actual storage area address, instead.

[00H] [08H] (0008H = 8 KB) to [0CH] [00H] (0C00H = 3072 KB)
However, the size must be as follows:

Sector size of the flash memory (128 KB) × n

Example A 512-KB TrueType font is downloaded.

{LDT; [00H] [C0H] [00H] [00H], [02H] [00H] |}

6.3 Program Data Command

Function Transfers program data.

Format {LP;nnnnnn ---- nnnnnn|}a

- 13 -

Term nnnnnn ---- nnnnnn: Program data in binary notation

a: Checksum: There are two conditions: 1-byte data, and that the result i s 0 when it is

added to the value obtained by adding up the all of nnnnnn ---- nnnnnn.

8. DATA

TRANSMISSION/RECEPTION

8.1 Loading from PC through RS-232C

After the TrueType Font Data Loa ding Prepare Command is sent, the next command should not be
sent until the PC receives a status indicating that preparation for loading is completed. The Program
Data Command should be divided into the size that matches the sectors, and then sent. The printer
starts writing the data in flash memory when the data sent for each sector reaches 64 KB. When the
writing of data for each se ctor is completed, the printer sends a status to request the next data. At
this time, the PC shoul d send the next data. When the writing of the last data is completed, the

8.2 Loading from PC through Centronics

printer sends a normal end status.

When loading data through the Centronics, the TrueType Font Loading Prepa re Command and
Program Data Command may be sent continuously. When the printer receive s the Tru eType Font
Loading Prepare Command, it prepa res for loading remaining in the B USY state. When the
preparation for loading is compl eted, the pr inter clears the BUSY stat e, and outputs a n ACK to
resume receiving the data. For the Program Data Command, when the printer receives the data of
one sector size, the printe r writes it in the flash memory remaining in the BUSY state. When the
writing of dat a of one sector si ze is completed, the printer clears the BUSY state, and out puts an
ACK to resume receiving the data.

10. TRUETYPE FONT DATA FORMAT

When the TrueType font data is loaded, the header is attached to the font data and they are
transferred as one data.

FONT HEADER (4 × 25

BYTES)

FONT
DATA

The font header is an index which indicates the start position of the font data, corresponding to the
font types of 01 to 25. Each index indicates the number of bytes from the start position of the font
header. If 0 is set for the i ndex, it means that there is no font data for the fo nt type. An index is a 4 ­byte data, and the byte list is little endian.

Ex.) When the font file for the font type “0” is placed immediately after the font header:

Font header = 4 × 25 bytes = 100 bytes = 64H bytes
Font index value: 00000064H

At the time, the header is as shown below:

TYPE 01 TYPE 02 TYPE 03

64 00 00 00 00 00 00 00 00 00 00 00 ·······
