1. A method for printing a graphic media product with a media printer, the method comprising the steps of:
- detecting an installation of a supply of a media substrate;
activating a sensor, based on the detection of the installation;
measuring a width of the installed media substrate with the activated sensor by counting truncated calibration dots positioned on the left and right of the media substrate, the calibration dots being disposed on the media printer;
computing a center position of the media substrate based on the measured width; and
marking the indicia upon the media substrate wherein the marking of the indicia is aligned relative to the computed center position of the media substrate.

Abstract
Printing a graphic media product is described. The media product has an indicia marked on a media substrate. An installation of a supply of the media substrate is detected. A sensor is activated based on the detection of the installation. The activated sensor measures a width of the installed media substrate. A center position of the media substrate is computed based on the measured width. The marking of the indicia upon the media substrate is aligned relative to the computed center position of the media substrate.

20. A graphic media product printed with a media printer using a process for marking an indicia upon a media substrate, the printing process comprising the method steps of:
-
detecting an installation of a supply of the media substrate for feeding to a printing head; activating a sensor, based on the detection of the installation of the supply of the media substrate; measuring a width of the installed media substrate with the activated sensor by counting truncated calibration dots positioned on the left and right of the media substrate, the calibration dots being disposed on the media printer and total number of the calibration dots corresponding to a maximum printing width of the media printer; computing a center position of the media substrate based on the measured width, the center position being computed relative to the printer and comprising adding half of the measured width of the installed media substrate to a total of one of the left or right truncated calibration dots; and aligning the marking of the indicia upon the media substrate relative to the computed center position of the media substrate.
