You signed up for MyPost Business, connected your eBay or Shopify store, and hit "print label." What came out of your thermal printer was either a tiny stamp-sized label, a blank page, or an A4 PDF that your 4x6 printer refused to touch.

Sound familiar? It happens to almost every Australian seller the first time they try printing MyPost Business labels on a thermal printer. The label generation side works fine. The printing side is where it falls apart.

This guide walks through the full setup: MyPost Business account creation, connecting your eBay or Shopify store, thermal printer configuration, and getting 4x6 labels that actually print correctly.

In this article:

Setting up your MyPost Business account

If you already have an account, skip ahead to the eBay or Shopify section. For everyone else, here's the process.

  1. Go to auspost.com.au/mypost-business and click "Sign up free"
  2. Enter your business details (ABN is optional for sole traders)
  3. Set your default sender address, this gets printed on every label
  4. Choose your preferred label format under Settings > Print Settings

The whole thing takes about five minutes. There's no cost to create an account, and you don't need a minimum parcel volume to get started.

Once you're in, you'll land on the MyPost Business dashboard. This is where you create labels manually, import orders, manage integrations, and track shipments.

Setting your label format early

Before doing anything else, go to Settings > Carriers > MyPost Business > Print Settings and change the label format from A4 to A6 (1 per page).

Skip this step and every label you download will be an A4 PDF with the shipping label crammed into one corner. Your thermal printer can't do anything useful with that.

Change it to A6 now. You'll thank yourself later.

Connecting eBay to MyPost Business

eBay has a direct integration with MyPost Business. No third-party app needed.

  1. Log in to your MyPost Business dashboard
  2. Go to Settings > Integrations
  3. Click Connect to eBay
  4. Sign into your eBay account when prompted
  5. Click I Agree to authorise the connection

Done. Your eBay orders will now show up in MyPost Business under the Orders tab. Select orders, generate labels, and print them from one screen.

What gets imported

When you connect eBay, MyPost Business pulls in:

  • Buyer name and shipping address
  • Item details and quantity
  • Order date and any buyer notes
  • The shipping method the buyer selected at checkout

You still need to enter the parcel weight and dimensions for each order (or set defaults). MyPost Business uses these to calculate postage and generate the correct label.

Bulk label printing from eBay orders

Once your orders are imported, select all the ones you want to ship, click Create Labels, confirm the weights, and hit Print. MyPost Business generates a single PDF with all your labels.

If you set your format to A6 earlier, each page in that PDF contains one 4x6 label. Send the PDF to your thermal printer, and they'll print one after another without any manual cropping.

Tracking numbers are automatically sent back to eBay and forwarded to your buyers. No copy-pasting needed.

Connecting Shopify to MyPost Business

The Shopify integration is slightly different. You can either use the direct connection or go through a third-party shipping platform like Starshipit or SellerDash.

  1. Log in to your MyPost Business dashboard
  2. Go to the eCommerce Partners section
  3. Select Shopify and click Connect to generate a token
  4. Copy that token
  5. In your Shopify admin, go to Settings > Shipping & Delivery
  6. Scroll to Carrier Accounts and click Connect account
  7. Select Australia Post and paste your token

Once connected, you can create and print shipping labels directly from your Shopify order fulfilment screen. Your MyPost Business savings band applies automatically.

Using a third-party shipping platform

If you sell on multiple channels (eBay, Shopify, Etsy, Amazon AU), a shipping platform like Starshipit, SellerDash, or ShipStation can pull orders from all your stores into one place.

The setup process:

  1. Choose a shipping platform that integrates with both Shopify and MyPost Business
  2. Connect the shipping platform to your MyPost Business account (each platform has its own guide for this)
  3. Connect the shipping platform to your Shopify store

This adds an extra step to the initial setup, but it means you can manage all your orders from one dashboard instead of jumping between MyPost Business and individual store admin panels.

For sellers doing fewer than 20 orders per day on a single platform, the direct MyPost Business integration usually works fine. The third-party platforms become worth it when you're juggling multiple sales channels or need features like automated carrier selection and batch processing.

Configuring your thermal printer for 4x6 labels

Account connected, orders importing. Now for the part that trips people up: getting your thermal printer to cooperate.

Printer driver installation

Most thermal printers need their manufacturer's driver installed before they'll work:

  • Dymo LabelWriter 4XL/5XL: Search "Dymo LabelWriter driver download" on dymo.com
  • Zebra ZD421/ZD220/GK420d: Search "Zebra printer drivers" on zebra.com
  • Brother QL-1100/QL-1110NWB: Download from brother.com.au/support
  • MUNBYN: Usually ships with a driver disc, or grab it from their website

Install the driver, plug in the printer via USB, and do a test print from the manufacturer's software to confirm it's recognised.

Setting the paper size

This is where most people get stuck. Your thermal printer needs to know it's printing on 100x150mm (4x6 inch) label stock, not A4 paper.

On Windows:

  1. Open Settings > Printers & Scanners
  2. Find your thermal printer and click Printing Preferences
  3. Set paper size to 100mm x 150mm (or 4" x 6")
  4. Set orientation to Portrait
  5. Save

On macOS:

  1. Open System Settings > Printers & Scanners
  2. Select your thermal printer
  3. Open the print dialog (Cmd+P from any app)
  4. Under Paper Size, select 100 x 150mm or create a custom size

If your printer doesn't show 100x150mm as an option, you may need to create a custom paper size. On Windows, this is done through the printer's advanced settings. On macOS, go to File > Page Setup > Paper Size > Manage Custom Sizes.

Thermal label printer loaded with 4x6 shipping label rolls

Before you commit to a full batch, print one test label:

  1. Download a single label from MyPost Business
  2. Open the PDF and send it to your thermal printer
  3. Check the output: is the barcode scannable? Is text readable? Is it centred on the label?

If the label is cut off, too small, or offset, the paper size setting is probably wrong. Go back and double-check that both MyPost Business (A6 format) and your printer preferences (100x150mm) are aligned. The shipping label printing problems checklist walks through the common fixes if the test label still looks wrong.

The A4 label problem and how to fix it

Even with the A6 setting in MyPost Business, you might still end up with A4 PDFs in some situations. eBay sometimes generates its own label format. Third-party platforms might override your settings. And if you're using MyPost Business to create manual labels (not from imported orders), the default can revert to A4.

When this happens, you have a few options:

Option 1: Change the setting in MyPost Business

Go back to Settings > Print Settings and make sure A6 (1 per page) is selected. This fixes most cases.

Option 2: Convert the A4 PDF before printing

For a one-off label, upload the PDF to the free A4 to 4x6 shipping label converter, choose the crop position, download the 4x6 version, and print it at 100% scale. You can still use the snapshot tool in Adobe Reader, but the converter is usually faster and avoids guessing the crop by hand.

Option 3: Use LabelChop to automate it

LabelChop watches your Downloads folder for A4 label PDFs, automatically crops them to 4x6, and sends them straight to your thermal printer. There's no manual step after the initial setup. If you're processing more than a handful of labels per day, this saves real time.

For a deeper look at the cropping problem, see our guide on how to crop MyPost Business A4 labels to 4x6.

MyPost Business savings bands explained

Beyond the convenience of printing labels from home, MyPost Business gives you cheaper postage rates through savings bands. Spend more, pay less per parcel.

There are six bands (0 through 5), based on how much you've spent in the last 4 weeks or 12 months, whichever gives you a higher band:

  • Band 0: Under $50 in the last 4 weeks (retail rates, no discount)
  • Band 1: $50 to $249 in 4 weeks, or $500 to $2,499 in 12 months
  • Band 2: $250 to $499 in 4 weeks, or $2,500 to $4,999 in 12 months
  • Band 3: $500 to $999 in 4 weeks, or $5,000 to $9,999 in 12 months
  • Band 4: $1,000 to $1,999 in 4 weeks, or $10,000 to $19,999 in 12 months
  • Band 5: $2,000+ in 4 weeks, or $20,000+ in 12 months

The discounts vary by destination. Same-city parcels under 5kg get the best deal at up to 40% off at Band 5. Interstate parcels under 5kg top out around 20% off. Rural deliveries get smaller discounts, maxing out at about 5%.

If you're doing 10 to 30 parcels per week, you'll probably land on Band 1 or 2. That's still noticeably cheaper than walking into a post office and paying retail rates over the counter.

You can check your current band in MyPost Business under the Send and Save tab.

Get your labels sorted

The whole MyPost Business setup takes about 15 minutes. eBay connects directly. Shopify uses a token. Both import orders and send tracking numbers to buyers without any extra work from you.

Where most sellers get stuck is the thermal printer configuration. Change your label format to A6 in MyPost Business before you print anything, set your printer paper size to 100x150mm, and run a single test label before committing to a full batch.

Still getting A4 PDFs despite all that? LabelChop watches your Downloads folder and converts them to 4x6 automatically. No cropping, no print dialogs, no wasted labels.
