Woosim Porti P340/P440 Panel Printer Series

This range includes the 3 and 4 inch versions of the low profile panel printer series. The Porti P340 prints on 80mm wide rolls whilst the P440 prints on 112mm paper.

The advantage of the wider format printers is to enable a larger number of dots to be printed on each line. This means you can print much larger characters, more standard characters, or improved graphics.

Despite the wide format capabiity, these devices still have an impressively shallow depth behind the panel making them ideal for slimline panels or very small enclosures.
