What you might need (vol.) is a variety of labellers, so you can mix it up to prevent a package profile being established for a specific vendor.To be honest you have to realize that all our intercepted packages wind up in an incinerator. They might take photographs (since handwriting = bad), but when you consider the volume of packages that Ebay produces alone...You have to be doing something pretty unique to stand out. Like fingerprints! There are more important concerns than which thermal printer you're using. Like having a proper staging area. Like mixing up your packaging style. Like randomizing your postal drops. Etc.
