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.
