===== ZPL =====

It is possible to make newlines for every new command. Some tutorials tend to stack several related, but different, commands on the same line.

<code zpl>
^XA

^FX The FX command starts a comment that ends at the next tilde 
or caret, but should be correctly terminated with a field separator command/symbol ^FS

^FX Print a box, 80 by 80 points (1cm) ^FS
^FO16,8^GB80,80,5^FS

^XZ
</code>

==== 38 x 13 mm Labels ====

Seems to be offset even though I specify dimensions. This ZPL places a box in the upper left corner and puts a text on the label

<code zpl>
^XA

^FO16,8^GB80,80,5^FS
^FO100,30^A0,40^FDWorks!^FS

^XZ
</code>

Apparently, the width is set to 330 points by the PC software, can be read by following commands

<code zpl>
^XA
^HH
^XZ
</code>

And can be updated with

<code zpl>
^XA
^PW304
^XZ
</code>

But to avoid conflict with the PC software it's probably better to move the Label Home, and then return it.

<code zpl>
^XA

^FO0,0^GB80,80,5^FS
^FO100,30^A0,40^FDWorks!^FS

^LH0,0
