Continuous Labels i75-series
When smart continuous labels are installed in the i7500 Printer, the ZPL script must include the [^LL] command for optimal printing. Sample script shown below.

Graphics & Fonts
If your script files use graphics or text that are not already on the printer, you will need to import them before running the script.
Minimum Font Sizes: The i7500 Label Printer supports the following minimum font sizes in scripts. If using ZPL, be aware that font sizes are not set explicitly, but rather with the bounding width and height.
- 5 pt minimum font size for 300 dpi printers.
- 4 pt minimum font size for 600 dpi printers
IMPORTANT! It is recommended that ZPL scripts be written in the dpi supported by your printer.
