When Peninsula Group’s representative asked me if I was interested in reviewing their completely rewritten Thermal Printer driver, I didn’t hesitate for a second. Peninsula Group’s printer driver is the only one that works with OS X without driving you crazy. The new printer driver includes a special installer to set up extraction of labels for use with UPS, FedEx, etc. once and then never look back. The rendering engine also makes it possible to print from web browsers without dithering — which is essential for barcodes to remain readable.
