Changing the resolution of a printer using a pulse train

摘要

A variable resolution print system is provided. The system includes a variable resolution printer coupled to a positional encoder and a configuration module. The position encoder provides a pulse train to a controller in the variable resolution printer, the pulse train representing the movement of a target relative to the printer. A user of the print system enters or sets a desired resolution for printing via the configuration module. The controller calculates the difference between pulses in the pulse train. The controller then determines an adjustment to the calculate difference based on the desired resolution. The adjustment is used to generate a pulse train that actuates one or more print head of the printer.

1. A variable resolution printer, wherein the printer has a fixed native resolution, comprising:
a controller configured to receive configuration data and a first pulse train having a plurality of pulses representing the movement of a target, wherein the configuration data specifies a desired print resolution, the controller including a module configured to calculate a difference between pulses in the first pulse train, to determine an adjustment to the calculated difference based on the desired print resolution, and to generate a second pulse train based on the determined adjustment; and a print head coupled to the controller, wherein the print head is configured to print indicia on the target based on the second pulse train generated by the controller; wherein the module is configured to calculate a correct pulse width for a next pulse in the second pulse train based on a prior average velocity of the target.
