The printer will accept four types of image files: .BMP, .IMG, .PCX and a special Datamax 7-bit ASCII file (as defined in this section). Using the Datamax 7-bit ASCII format will require at least twice as much data transmission time as the other formats (see <STX>I). The Datamax ASCII image file format is made up of a set of records with identical formats, each representing a dot row of the image. The last of these records is followed by a terminator.

Dot-row record

Dot-row record

Terminator

Each dot-row record has the following format:

Syntax:80nndd...d<CR>

Where:

nn

-

Number character pairs in dd...d, represented in ASCII hex.

 

dd…d

-

Dot data, character pairs, ASCII hex, 00-FF

Duplicate records may be encoded using a repeat data record, following the data record that needs duplicating. The repeat data record format is:

Syntax:0000FFnn<CR>

Where:

nn

- Is the number of duplicates, ASCII hex, 00-FF.

The terminator, last record, at the image download is: FFFF<CR>
