Abstract
In a control method for image data including binary image data and multilevel image data, line information is attached to line print data for each of lines forming the image data and then the line information and the line print data are stored for each line in a memory. The line information is used to determine whether a data block included in the line print data is one of a binary image data block and a multilevel image data block. The binary image data block and the multilevel image data block for each line are processed according to the line information so as to produce a printed image of the image data.
Claims20
A control method for image data including binary image data and multilevel image data, comprising the steps of:
- a) attaching line information to line print data for each of lines forming the image data, wherein the line information is used to determine whether a data block included in the line print data is one of a binary image data block and a multilevel image data block;
- b) storing the line information and the line print data for each line in a memory;
- and
- c) processing the binary image data block and the multilevel image data block for each line according to the line information so as to produce a visible image of the image data.
A printer for printing image data including binary image data and multilevel image data, comprising:
- a memory storing line information attached to line print data for each of lines forming the image data, the line information is used to determine whether a data block included in the line print data is one of a binary image data block and a multilevel image data block;
- a discriminator for discriminating between the binary image data block and the multilevel image data block according to the line information;
- a data processor for processing the binary image data block and the multilevel image data block for each line to produce print image data;
- and
- an output device for outputting a visible image from the print image data.
A memory for storing a program for controlling a microprocessor provided in a printer for printing image data including binary image data and multilevel image data, the program comprising the steps of:
- a) storing line information attached to line print data for each of lines forming the image data, the line information is used to determine whether a data block included in the line print data is one of a binary image data block and a multilevel image data block;
- b) discriminating between the binary image data block and the multilevel image data block according to the line information;
- c) processing the binary image data block and the multilevel image data block for each line to produce print image data;
- and
- d) outputting a visible image from the print image data.
