Q-Connect Universal Self-Adhesive LabelsSuitable for laser printers, inkjet printers, and copiersLabel size: 105 x 148.5 mmWhiteness CIE: 150Color: WhiteNumber of labels per sheet: 4Recommendations:If you are printing just one label, select the four-field print option in the carrier's application (bottom right field), to ensure the printer roller can easily re-feed the sheet without issues. Printers generally don't prefer so-called "butter paper" running through them.If your printer struggles to feed the sheet, place a few plain A4 papers underneath the label sheet in the tray. This is because the paper is delicate and narrow, and not all printers can feed a single sheet alone.Insert the sheet straight; carrier barcodes are usually positioned at the edge of the labels, so it's essential to have them fully printed, otherwise, they might not be properly scanned at check-in.Stick the label with the printed address smoothly to avoid wrinkles in the barcode area, as this might cause issues during package reception.
