Chapter 4. Record Formats
Two-Byte Image Line (SIL)
Two-Byte Image Line (SIL)
The SIL record contains the characters for a line of print. It is the same as
the IML record except that two bytes are used to identify each character.
For a category I super font, the first byte is for the subfont number and the
second byte is for the character within that subfont. A category II font is
not divided into subfonts so the two bytes simply identify the desired
character. The current font must be a super (double-byte) font when this
record occurs or an error occurs and printing stops.

If there is no text included, a blank line will be printed.
If the multi-part line mode is enabled by an MPL record, the cursor is left
at the end of the text printed by this record and is not positioned for the
next line.
1-2 2 Record Length The length of this record, in binary, including the record length
field. For example, hex 00 30 specifies a record length of 48 bytes.
3 1 Cyclic Record Count A binary cyclic record count using modulo 256. Each record in the
job is counted, starting with hex 01 for the first record. The 255th
record is hex FF and the 256th record is hex 00. This count is used
to verify record sequence.
4 1 Control Code A binary code that identifies the record type. A value of hex 2B
identifies the SIL record.
5-n n Print Line A character string representing a line of text. The character coding
must agree with the coding of characters in the font. There is no
end-of-line character.
Each character is identified using two bytes.
