(7) Load Horizontal Tab Stop Data command

The Load Horizontal Tab Stop Data command loads horizontal tab stop data
into the horizontal control buffer

Example:

35 20 4E

Parameter sequence

Codes used in the parameter sequence are the same as those of the Load FCB
Data command.

Code 35 in the parameter sequence above indicates that the

horizontal tab stop is to be set at column 5.

Code 31 35 indicates that

the horizontal tab stop is to be set at column 15.

Using this parameter,

the horizontal tab stop is set at columns 5, 15, 25, and

If the column for the horizontal tab stop exceeds the

margin, the

printer regards it as an invalid horizontal tabulation

data command

and clears the horizontal control buffer.

Status Request command

The Status Request command directs the printer to report its status to the
host.

Even if the DTR signal is off, the printer can receive this command

and report printer status.

If the

Reverse Channel line, or DTR line protocol is used and

the host receives code XOFF from the printer, or if the Reverse Channel is

off (for example, the printer interface buffer is almost full) and the

host transmits this command, the interface can be used efficiently.

(9) Status Response

The Status Response command, in response to the Status Request command

transmitted from the host, reports the printer status in the following
format:

Example:

90 24 31 30; 31 33; 34 30; . . . . . . . . . .
