3.2 Operating Modes

This section provides a functional overview of how the printer receives print data from your host computer and how it will operate in the various

operating conditions. This section also shows you how to install the TEC Printer Drivers into your computer.

Labels will be created on the host computer connected to your printer, using either a commercially available label creation program or using the TEC Command Program Language. Or if the optional PCL5 Interface Board has been installed, the printer will be able to print from any software using the HP-PCL5 Printer Command Language. The label information sent from your host computer will consist of a series of commands that inform the printer of the labels size, layout, orientation, and number of copies to print and will also contain the print data including scaleable text, graphics, and bar codes. The printer electronics will decode the commands and manipulate the data to create a bit graphic image of the label that will be stored in the printer’s memory. The printer electronics will then transfer the image as a series of dots, one line at a time, to the thermal print head.

The thermal print head consists of a line of 2560 thermal elements with each element shaped like a tiny dot. The dot line is 8.5 inches (216.8

mm)in length resulting in a dot density of 300 DPI. As the paper is advanced through the printer by the paper feed mechanism, the thermal head continuously prints the image as a series of dot lines at a resolution of 300 dots per inch, horizontally and vertically.

Precision feeding and back feeding of the label or tag stock is accomplished through the use of specialized stepping motors and photo- sensors. The label gap sensor or the black mark sensor tells the printer electronics when the label or tag stock is properly positioned under the head for accureate printing.

1.Tear Off Mode – In this operation mode, when the media has stopped feeding after printing, the label should be in a position that the operator can simply pull the media downward against the tear off bar to tear off the printed label.
