Please take care when loading these sheets into your printer tray. The new manufacturer of this Brand has used an UN-printed material for the backing sheet. Please double-check that labels are inserted correctly before printing. Should you wish, we will happily replace any 'blank-back' label sheets that do not meet your requirements. Customers ordering this product from our webstore will be notified of this potential problem BEFORE their order is fulfilled. As always, our PRICE-MATCH PROMISE will apply to any replacement supplied. For example, this product code ' value392272 ' would be replaced by Xerox912254 or 5Star328489 ...whichever you prefer. Product Code ' value392272 ' carries an EAN # (BarCode) 5055792392272 registered to Exertis (UK) Ltd. Please use that EAN if comparing prices, to ensure that alternative suppliers are quoting for the identical product. There's ALWAYS a cheaper alternative... but... how-low-do-you-go before an item is UN-usable?
