Transmilles ProCal, ProCal-Track, ProCert and ProSales software all support printing directly to labels for generation of certificate labels, job labels and much more.

Printed labels include barcodes and logos and can be configured by end users to show or hide additional information

The current list of supported label printers can be found below : 

Seiko Smart Label Printer (Using label code SLP-TMRL)

Brother Label Printers (P-Touch 2430 and compatible)

Dymo 300/400 Series Printers

The above list applies for ProCal & ProCal-Track Version 5 onwards.

Other printers that use Serial Connections (ASCII Output) can be used, but are not as configurable as the supported printers.
