Automatic print speed control for indicia printer
First Claim
Patent Images
1. A method for printing a label using a variable speed printer, comprising the steps of:
- optimizing a printing speed of the variable speed printer through a proportional-integral-derivative controller for a new print job based on a print duration and print processing duration history of one or more previously completed print jobs, such that an actual print duration of the new print job is equal to or greater than a print processing duration of a queued print job; and
automatically adjusting the printing speed based on the optimized printing speed, the variable speed printer executing the new print job at the optimized printing speed and transitioning to printing the subsequently queued print job without having to increase or decrease the printing speed.

Abstract
A label printing device and method include a proportional-integral-derivative controller and a variable speed printer motor. The variable speed printer motor is connected to the proportion-integral-derivative controller, and has an automatically optimized printing speed determined by a print duration history of one or more previously completed print jobs.

14. A barcode label printing device comprising:
-
a proportional-integral-derivative controller; and a variable speed printer motor connected to the proportion-integral-derivative controller, and having an automatically optimized printing speed determined by a print duration and a print processing duration history of one or more previously completed print jobs, such that an actual print duration of a new print job is equal to or greater than a print processing duration of a queued print job, and the new print job is performed at the optimized printing speed and transitions to printing the subsequently queued print job without having to increase or decrease the printing speed. - View Dependent Claims (15, 16, 17, 18, 19, 20)
