Get help with PrintFlex

Last updated: 21 September 2026

PrintFlex is in development and early access, so support is the founders reading their email. Write to us and a person who builds the app will reply.

What to include in a report

The more of this you send in the first email, the faster we can fix it:

• Your store URL, for example yourstore.myshopify.com, so we can find your install.
• The order number or numbers involved, exactly as Shopify shows them.
• Which document you were generating: invoice, packing slip or pick list, and which template.
• What you expected and what happened instead. A screenshot or the PDF itself helps a great deal.
• For scan mode problems: the phone or scanner model and the browser you were using.

Quick troubleshooting

• The camera won't scan the QR code. Give it more light and hold the phone still about 15 cm from the page. If the handset is old or the browser has no camera barcode support, use a USB scanner on the Code 128 barcode instead, or type the order number into the field on the scan page.
• The document looks wrong. Open the template in the app and check its toggles: prices, taxes, discounts, phone number, notes and HS codes can each be shown or hidden, and the live preview shows exactly what will print. Check the paper size (A4 or Letter) matches your printer.
• An order is missing from the dashboard. Check the active filters first, then the order's fulfillment status in Shopify. A saved view that filters on "Unfulfilled" will hide orders that have since been fulfilled.
• An order shows "Printed" but nobody printed it. Another staff member may have generated a document from a different batch. The status is shared across the whole store so the same order is not shipped twice.
• The pack screen asks for a PIN. The PIN is set by the store owner in the app's Scan mode settings. Staff need to ask the owner; we cannot read or reset it by email without verifying the store.
• Billing questions. All charges go through Shopify. Your Shopify invoice lists the PrintFlex plan, and you change or cancel the plan from inside the app or by uninstalling it.
