We've got a p-touch hooked to the computer. Are you using the standard tapes? Or one of their "hi-strength" specialty types?

Thanks

PtouchDirect Standard TZ Tape Guide - What Brother TZ Tape Color Is Right For You? Laminated Brother tz tapes stick to virtually any surface and are durable enough to withstand scrapes and abrasions. Because TZ TAPES are water resistant, they can be used outdoors, as well as indoors. They shrug off spills of any kind; from water, to oil, to chemicals and won't fade under harsh UV rays. And these tz labels stay on through hot and cold environments from freezers to microwaves. Brother has P-touch tz laminated tapes down to a science.   Other Brother TZ Tape Guides: Extra Strength TZ Tapes, Specialty TZ Tapes   Click here to View, save or print Tape Guide   Just click on the tape number you need - it's that easy!
