1. Introduction
1.1 Product Introduction
Thank you very much for purchasing barcode printer.
The LTT324 printer features two durable gear-driven motors that are capable of handling large capacity
300-meter ribbons and large rolls of media inside its sleek design. If the 5” interior label capacity is not
enough, simply adding an external media roll mount and the LTT324 can easily handle 8.4” OD rolls of
labels designed for expensive industrial label printers.
The moveable sensor design can accept wide range of label media. All the most frequently used
barcode formats are included. Fonts and barcodes can be printed in any one of the fourdirections.
The simulation models are built in font of high quality and efficient (True Type font) and font engine. With
flexible firmware design, user can also download the True Type Font from PC into printer memory for
printing labels. Besides the scalable font, it also provides a choice of five different sizes of alphanumeric
bitmap font, OCR-A and OCR-B fonts. By integrating rich features,it is the most cost-effective and high-
performance printer in its class!
To print label formats, please refer to the instructions provided with your labeling software; if you need
to write the custom programs, please refer to the XPL programming manual that
can be found on the accessories CD-ROM.
