Control apparatus, storage medium in which control program is stored, and printer to execute a plurality of processing in parallel

A non-transitory computer readable storage medium in which a control program is stored, the control program being usable for a printer which is configured to communicate with an external apparatus and to include a printing section, a display section, and a storage section which is configured to store image data to be supplied to the display section and first data transmitted from the external apparatus, and the control program making the printer execute a plurality of processing comprising:

• a first processing in which the image data is supplied to the display section;
• a second processing which is to be executed in parallel with the first processing, and in which a predetermined image processing is applied to the first data to generate second data to be stored in the storage section;
• and
• an identifying processing in which the number of the second data stored in the storage section,
• wherein in a first case, in which the number of the second data identified by the identifying processing is smaller than a predetermined threshold value, the control program makes the printer execute the first processing such that a proportion of time for the first processing to unit time is a first proportion, and
• in a second case, in which the number of the second data identified by the identifying processing is the predetermined threshold value or larger, the control program makes the printer execute the first processing such that the proportion of the time for the first processing to the unit time is a second proportion which is greater than the first proportion.

A printer which is configured to communicate with an external apparatus, comprising:

• a printing section;
• a display section;
• and
• a control section which is configured to control the printing section and the display section, to include one central processing unit and a storage section which is configured to store image data to be supplied to the display section and first data transmitted from the external apparatus,
• wherein the central processing unit is configured to function as:
• a first processing executing section which is configured to execute a first processing in which the image data is supplied to the display section;
• a second processing executing section which is configured to execute a second processing, which is to be executed in parallel with the first processing, and in which a Raster Image Processer processing is applied to the first data to generate second data to be stored in the storage section;
• a third processing executing section which is configured to control the printing section to execute a third processing, which is to be executed in parallel with the second processing, and in which the second data stored in the storage section is printed on a recording medium;
• and
• an identifying section which is configured to identify the number of the second data stored in the storage section,
• wherein in a first case, in which the number of the second data identified by the identifying section is smaller than a predetermined threshold value, the first processing executing section is configured to execute the first processing such that a proportion of time for the first processing to unit time is a first proportion, and
• in a second case, in which the number of the second data identified by the identifying section is the predetermined threshold value or larger, the first processing executing section is configured to execute the first processing such that the proportion of the time for the first processing to the unit time is a second proportion which is greater than the first proportion, and
• wherein the third processing executing section is configured to wait to execute the third processing in a case that the second data is not stored in the storage section, the third processing executing section is configured to execute the third processing in a case that the second data is stored in the storage section, and
• the number of second data which is stored in the storage section is decreased by the third processing being executed.
