UPS ShipConfirm Request for label printing

Question

Could anyone tell me what I need to specify in LabelSpecification section of UPS xml request document in order to print EPL shipping label? The following is what I have:

  <LabelSpecification>
    <LabelPrintMethod>
      <Code>EPL</Code>
    </LabelPrintMethod>
    <HTTPUserAgent>Mozilla/5.0</HTTPUserAgent>
    <LabelImageFormat>
      <Code>GIF</Code>
    </LabelImageFormat>
  </LabelSpecification>

But I keep getting the following error in the response:

Missing/Invalid Combination of LabelSpecification/LabelStockSize

I've tried using 'EPL2' as well with no avail. And I've no idea where to specify LabelStockSize. UPS website isn't very helpful in this regard. Thanks in advance.

Answer 1

Yahooing, I found examples like this:

<LabelSpecification>
  <LabelPrintMethod>
    <Code>EPL</Code>
  </LabelPrintMethod>
  <LabelStockSize>
    <Height>4</Height>
    <Width>6</Width>
  </LabelStockSize>
</LabelSpecification>

and this:

<LabelSpecification>
  <LabelStockSize>
    <Height>4</Height>
    <Width>6</Width>
  </LabelStockSize>
  <LabelPrintMethod>
    <Code>EPL</Code>
    <Description>epl file</Description>
  </LabelPrintMethod>...

In other words, it looks like <LabelStockSize> needs to be a child of <LabelSpecification>, but can come before or after <LabelPrintMethod>.
