Abstract
An image formation device having computer readable instructions that alleviate the necessity of the user to enter the correct page size into the image formation device. The computer readable instructions contain, among other things, a look-up table, or map, of known print media dimensions the image formation device is able to handle. The size of the media loaded into the image formation device is detected and assigned a value according to the look-up table, or map, of the computer readable instructions. The value is compared to the known types of media that are supportable by the printer. These types of media are grouped into predetermined categories according to their respective width dimensions. A determination of whether the image formation device performs a function is made based on the comparison of the converted value to the predetermined group of media.
