What is TSPL?

TSPL (TSC Printer Language), also called TSPL2, is the command language of TSC thermal printers. Many budget desktop label printers, including some sold under other brands, use it. A 4×6 thermal printer that isn’t a Zebra often uses TSPL.

Example

Section titled “Example”
SIZE 4,6
GAP 0.12,0
CLS
TEXT 50,50,"3",0,1,1,"LabelZoom"
BARCODE 50,120,"128",100,1,0,2,2,"12345678"
PRINT 1

TSPL puts one English-word command on each line. SIZE sets the label size, GAP sets the gap between labels, CLS clears the image buffer, TEXT and BARCODE draw fields, and PRINT prints the label. Field coordinates are in dots.

Convert TSPL files

Section titled “Convert TSPL files”

These free tools run in your browser:

The LabelZoom API converts TSPL to and from ZPL, PDF, and images. For example, POST /api/v2/convert/tspl/to/png renders TSPL as an image. If your shipping platform produces ZPL and your printer uses TSPL, convert the label with POST /api/v2/convert/zpl/to/tspl, or convert it to PDF and print it through the printer’s driver. Save TSPL output as bytes, not text; see Binary output.
