Applications Overview
Label Tutorial
This section guides the reader through a examples designed to teach the reader how to create basic labels. The tutorial starts with a simple label with a plain text string. The tutorial builds on this example by introducing a single concept in each subsequent example. By the end of the tutorial, the label will contain text, lines, boxes, and a bar code. Each step also provides background on the PAL operators, helping the reader understand the example code.
NOTE:
For the PAL code segments presented, it is assumed that the command lines will be entered via some form of terminal emulation package or as a transmitted string from the host. The lines are to be terminated by pressing the [ENTER] key if using a terminal emulator or by sending a Carriage Return [CR] character. A Line Feed [LF] following the carriage return is also acceptable. The sample code will not explicitly show the end of line terminations. If the printer is in executive mode, there will be a PAL> prompt issued at the completion of each command.
The PAL command interpreter is case sensitive!!! All commands must be entered using the same case as in the examples and in the Programmer’s Reference Manual.
Each step of the tutorial is presented on a single page with a diagram of the label output, the commands used to produce the label and descriptions of the PAL commands. Shading is used to call attention to code that has been added to the previous example to introduce a new concept. The detailed descriptions of the commands only cover the commands in the shaded area since the rest of the commands have already been covered in previous examples.
