2. About Raster Commands

Using raster commands an RJ-XXXX printer (where “XXXX” is the model name) can be used to print without using our printer driver. This operation is useful in the following situations. ⚫ When printing from an operating system other than Windows

(Example: When printing from a Linux computer or mobile terminal) ⚫ When adding print functions to an existing system In addition, printing can be performed with advanced settings.

In this material, “raster” refers to binary bitmap data (collection of dots).

Refer to this material to print by sending initialization commands and control codes together with raster data to

the RJ-XXXX printer (hereafter, referred to as “printer”). This manual describes the procedure for adding these codes and sending the data.

3. Printing Using Raster Commands

(1) Open the USB/network port

Open the USB/network port in the operating environment. The procedure for opening the USB/network

port is not described in this material.

(2) Confirm the printer status sent from the printer

The “status information request” command is sent to the printer, the status information received from the

printer is analyzed, and then the status of the printer is determined.

For details on the “status information request” command and on the definitions of “status”, refer to “Status

information request” in “7. Printing Command Details”.

(3) Send the print data

If the status analysis confirms that media compatible with the print data is loaded into the printer and that

no error has occurred, the print data is sent. The structure of the print data is explained in the next section, “4. Print Data”.

Note:

No command can be sent to the printer after the print data is transmitted and until the completion

of printing is confirmed. Even the “status information request” command cannot be sent during printing.

(4) Print the data

(5) Confirm that printing is completed

When printing is completed, the status is received from the printer. If this status is analyzed to confirm that printing is completed, printing one page is considered finished. If the print job has multiple pages, (2) through (4) are repeated.

(6) Close the USB/network port

After all printing is finished, close the USB/network port.

⚫ When the printer is turned on, it is in the receiving state. When printing begins, the printer changes to the

“printing” phase (phase type: printing state; phase number: printing) and sends that phase status to the

computer. When printing has finished, the printer sends the “printing completed” status to the computer.

When the “printing completed” status is sent, the printer changes to the “receiving state” phase status

(phase type: receiving state; phase number: waiting to receive) and sends that phase status to the

computer.

Unless an error occurs during printing, the printer sends the “printing completed” status.

Parameters

Definitions of {n}

No-compression mode (Enabled)

Reserved (Disabled)

TIFF (Enabled)

Description

⚫ Selects the compression mode. Data compression is available only for data in raster graphic transfer. ⚫ Registry has to be added in order to use TIFF compression mode on RJ-4200.

For details, refer to section 4.2.1 Preparation.

[TIFF(Pack Bits)]

⚫ 1-byte units ⚫ If the same data is repeated, the number of data units and that 1 byte of data are specified.

If different data is in a series, the number of data items and all of the different data are specified. ⚫ If the same data is repeated, the number of data units is specified as the actual number minus 1,

expressed as a negative number.

If different data is in a series, the number of data units is specified as the number of bytes minus 1,

expressed as a positive number. ⚫ If the above process results in more than 104 bytes of compressed data with RJ-4200, 72 bytes of

compressed data with RJ-3000 or 54 bytes of compressed data with RJ-2000, the data is treated as

being all different. As a result, the data will be 105 bytes with RJ-4200, 73 bytes with RJ-3000 or 55 bytes

with RJ-2000, including the 1 byte that specifies the data length.

Example 1 raster of raster graphics transfer:

Without compression:

00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 22 22 23 BA BF A2 22 2B……

With compression:

ED 00 FF 22 05 23 BA BF A2 22 2B … a b c

Since “00h” is repeated for 20 bytes, 20d -> 19d -> 13h changed into a negative number is EDh. Therefore: ED 00

Since “22h” is repeated for 2 bytes, 2d -> 1d -> 1h changed into a negative number is FFh. Therefore: FF 22

The following 6 bytes remain unchanged. 6d -> 5d -> 5h Therefore: 05 23 BA BF A2 22 2B

7. Printing Command Details

Explanation of “TIFF compression mode” With compression, the data for the “raster graphics transfer” command is based on 104bytes (RJ-4200), 72 bytes (RJ-3000) or 54 bytes (RJ-2000) of the total number of pins (RJ-4200: 832, RJ-3000: 576 and RJ-2000:

432). As shown below, with no compression, the sum of the number of offset pins and the number of pins

within the print area is the byte data. However, with compression, the number of unused pins is also added to

the data. In other words, with compression, this becomes 104 bytes with RJ-4200, 72 bytes with RJ-3000 or 54 bytes with RJ-2000 when it is expanded by the machine, regardless of the tape width.
