The print mode includes the standard mode, page mode, and the batch rotate print mode.

Standard mode
Prints line by line. Line spacing is automatically adjusted according to character size, image size, and barcode height. Suitable for printing receipts whose print length varies by print content.
Page mode
Prints page by page. Prints characters, images, and/or barcodes on a single page that is defined as a print area.

When processing in the page mode, use addPageBegin method to start and addPageEnd method to end the page mode process, respectively.
Batch rotate print mode
This is a print mode in which the range of the print data (such as characters, images, barcodes, etc.) is set, the print data in the set range is compiled, inverted, and then printed.

When performing the processing in the batch rotate print mode, start the batch rotate print processing with addRotateBegin method, and end the batch rotate print processing with addRotateEnd method.

The APIs that can be used in each mode are described in the table below.
