Image forming apparatus, printing method, and computer-readable recording medium that has stored control program

A printing method, comprising:

• forming an image on a recording medium conveyed on a conveyance path;
• and
• controlling image formation on the recording medium by:
• acquiring, with a sensor, first information on a first paper characteristic of the recording medium without classifying the first information to any paper kind;
• after acquiring the first information, acquiring, with the sensor, second information on a second paper characteristic of the recording medium without classifying the second information to any paper kind;
• and
• determining a parameter for controlling the image formation and conveyance of the recording medium based on a difference between the first information and the second information and controlling the image formation based on the parameter.

A non-transitory computer-readable recording medium storing a control program that controls an image forming apparatus, the program causing a computer to execute:

• forming an image on a recording medium conveyed on a conveyance path;
• and
• controlling image information on the recording medium by:
• acquiring, with a sensor, first information on a first paper characteristic of the recording medium without classifying the first information to any paper kind,
• after acquiring the first information, acquiring, with the sensor, second information on a second paper characteristic of the recording medium without classifying the second information to any paper kind, and
• determining a parameter for controlling the image formation and conveyance of the recording medium based on a difference between the first information and the second information and controlling the image formation based on the parameter.
