I know printing the correct barcode label is important to your business, Jksanford.
For now, when you choose the Continues (Perforated Edge) printer type, it will only let you choose Avery and Rolodex cards formats. You may continue using the Label Printer (Single Label) type so you can print a 4"x5" label format. That's currently the biggest barcode label.
We're currently unable to add a template for your printer. We'd appreciate it if you could let us know about your preferences by sending feedback. Your valuable suggestion goes to our Product Development team to help us improve our system. You can do that by going to Help, clicking Sending Feedback Online, then choosing Product Suggestion.
We always appreciate customers who take the time to give us their feedback. I’ll also pass your idea to our management team.
I've got you an article for future reference: Use barcode scanning.
We're just here if you need more help. Don't hesitate to come back anytime.
