Before you can use Printlane, you need to enable it in your current Shopify theme:

  1. Open your Shopify Admin
  2. In the navigation, click on Online Store -> Themes: Themes in your Shopify Store
  3. Click on Customize next to Current theme: Customize the current theme
  4. In the navigation, click on App embeds and enable Printlane: App Embeds of your current theme
  5. Save your theme: Save your theme changes

If you switch to another theme in the future, you need to follow the above steps again.

Customize products

Now Printlane is enabled, you can activate the designer for one of your products. We'll use one of the demo templates in your Printlane account.

  1. Open Printlane Studio
  2. Edit a demo template and click on the Shopify tab
  3. Select one of the products from your Shopify store
  4. Click on Save
Enable designer for a product

The Shopify product you selected will use this template in the designer.

Open the product page in your Shopify store. It will display a button Personalize instead of Add to cart. You can customize the product by clicking on the Personalize button.

Read our full guide on Creating templates if you like to create and link your own templates.

Designs in the shopping cart

A unique reference to the design is displayed after adding a product to the shopping cart:

Customization reference in cart

This reference is stored in a line item property, allowing customers to add the same product multiple times to the shopping cart with a different design.

Changing designs from within the shopping cart

You can replace design references with links that allow your customers to review and change designs from withing the shopping cart.

To do so, you'll need to update your theme's cart liquid code:

  1. Open your Shopify Admin
  2. In the navigation, click on Online Store -> Themes: Themes in your Shopify Store
  3. Click on the Actions dropdown for your Current theme, and choose Edit codeEdit code of your current theme
  4. Open the cart liquid file. It's usually named main-cart-items.liquid, cart.liquid, cart-template.liquid or form-cart.liquid. This file should contain code that loops over each line item's properties:
    {% for property in %}
      ... code that prints properties here
    {% endfor %}
  5. Add a conditional statement looking for customization reference, and print a link:
    {% for property in %}
       {% if property.first contains 'customization reference' %}
          <a href="#" class="printlane-open" data-printlane="{{ property.last }}">Change design</a>
       {% else %}
          {{ property.first }}: {{ property.last }}
       {% endif %}
    {% endfor %}
    For a complete overview of all tags, please refer to Shopify's Liquid documentation.
  6. The design references are now shown as links and will open the Printlane Designer when clicking on them: Edit designs in the shopping cart


Please take into account that design references will always be displayed in the Shopify Admin, on checkout pages and confirmation emails.

Displaying thumbnails of designs

First allow changing designs

To display thumbnails of the created designs on the shopping cart page, you first need to make sure that users can review and change designs on the shopping cart page (see above).

Printlane offers functionality that generates a thumbnail of the design that you can use to display in the shopping cart. You can think of this as a screenshot of what was last displayed in the designer application right before the customer added the product to the shopping cart.

You can enable this if you're displaying links to change designs (see previous step) and by following these steps:

  1. Open your Shopify Admin
  2. Click on Online Store in the navigation
  3. Next to Current theme click on Customize
  4. Click on Theme settings -> App embeds
  5. Expand Printlane and tick the checkbox Replace cart thumbnailsEnable cart thumbnails
  6. Save your theme

After enabling this functionality, follow these steps to ensure it works:

  1. Navigate to a customizable product page
  2. Create a design and and add it to your shopping cart
  3. The shopping cart should now replace the original image in with a thumbnail of the design

If you're experiencing difficulties having the thumnails to appear, please check:

  • if the Cart row selector is correct. It should be a CSS selector string that matches all cart line items.
  • if the items in your shopping cart were added before ticking the checkbox Replace cart thumbnails. These items won't have a thumnail available yet.

Uninstalling or cancelling Printlane

If you want to stop using Printlane or cancel your subscription, you can simply do so by uninstalling the app from your Shopify store:

  1. Open your Shopify Admin
  2. Click on the Apps link in the left sidebar
  3. Under installed apps, you'll see Printlane, click on the "waste bin" icon
  4. Confirm uninstalling Printlane

All access to your Shopify store and data is now revoked. Your data in Printlane will be automatically erased according to our data processing policy.

You might have done changes to your theme's liquid code to allow customers to change designs from their shopping cart (see 4. Designs in the shopping cart).

To revert these changes, please follow these steps

  1. Open your Shopify Admin
  2. In the navigation, click on Online Store
  3. Click on the Actions dropdown for your Current theme, and choose Edit code
  4. Find the cart's liquid file (usually named cart.liquid, form-cart.liquid or cart-template.liquid)
  5. Open the file and remove the code that was added earlier
  6. Save you Shopify theme


I need help with integrating Printlane in my Shopify store

If you aren't able to get Printlane working by following all steps described in this document, please contact our support department by following the Support-link in Printlane Studio.

Take into account some time for our support to respond to your request for assistance.

I've switched to another theme and Printlane is not working anymore

When you publish or prepare another theme, you need to enable Printlane in that theme as well. Please go to 2. Enable Printlane in your theme and apply all steps to the new theme.

Customers can add products to my cart without customizing

Some Shopify themes come with "Quick add" functionality or show Add to cart buttons on catalog or collection pages. Shopify does not support creating designs from overview pages.

To prevent customers adding products without designs, please take a look at your theme's settings and disable Quick Add functionality or hide Add to cart buttons from overview pages to prevent this from happening.

When clicking the personalize button, the Printlane Designer doesn't open

When the text on the Add to cart button is changed to Personalize, Printlane is enabled and the designer for the product is active.

However, some Shopify themes implement functionality that override the default way of adding products to the shopping cart, which can break the Printlane integration.

If you happen to see the Personalize-button, but the Printlane Designer does not open when clicking the button, please take a look at your theme settings and disable any functionality like "Add to cart using Ajax" and / or setting the Cart type to Page: Setting the cart type in your Shopify theme settings

How do I hide the Buy it now button on product pages?

Some themes display Buy it now buttons next to the regular add to cart buttons. These are called dynamic checkout buttons and can't be configured to work with Printlane.

Buy it now buttons on product pages

To prevent customers from buying products without a design, you need to disable these buttons.

  1. Open your Shopify Admin
  2. Click on Online Store in the navigation
  3. Next to Current theme click on Customize
  4. Navigate to a product page
  5. Click on the Buy buttons item in the navigation and uncheck Show dynamic checkout buttonsDisable dynamic checkout buttons
  6. Save your theme

When linking or updating a Printlane template to a Shopify product, the changes are not immediately visible

When you initially link a template to a Shopify product, it might take up to a minute for the Personalize button to show on the product page.

Choose Shopify product variants

This is because Shopify might cache your product page, and the changes haven't come through just yet.

This also happens when updating the product or the variants for which the template is used. Please allow some time for Shopify to display the changes.

How can I hide the design reference on checkout pages?

Shopify does not allow to change checkout pages unless you have a Shopify Plus subscription. If you have such a subscription, you can override the checkout pages.

If you make changes to your checkout code, then you need to upgrade your checkout.liquid template manually whenever Shopify makes an upgrade. We advise to use the default checkout provided which displays the design reference.

I've received an order, how do I see it's design?

Every customized order line has a unique Printlane reference, for example 1.03dc0b02-8431-4ac8-9bfa-f32d279554d5: Design reference in order detail

The first part before the dot is a number, 1. This is the ID of the design, a number that increases automatically when creating more designs. You can lookup the ID in the list of designs in Printlane Studio.

Paste the ID 1 in the Search by ID filter on top of the page and click on the search-button to find the corresponding design: Design reference in order detail

Did you know you can also lookup orders in Printlane Studio? This page shows all orders that contain at least one order line with a design reference. Orders and order lines without referenced designs are not available in Printlane due to data processing regulations.

I want to remove Printlane code or snippets from my theme

Please follow the uninstall instructions in Uninstalling or canceling Printlane.
