I think how you would handle it depends upon your needs. I don't think you can configure a report size to manage this, but you could either turn off the header and footer or configure a header/footer on every page.

Perhaps you could give more details as to your requirements.

hello @darylbowman , the idea is to print a purchase ticket, like the one that gives you in a retail store. This ticket adjust the size depending on the item lines,  but I don't know if there is a configuration for the paper rolls for thermal miniprinters like the one in the picture.

I configured a report for this once. Rather than use a pre-defined PaperKind, I used Custom and entered the paper width manually. Then, for the length, I entered a size as long as I thought the longest report would need to be. This should allow for the report to adapt to the required length as necessary.

Thanks @darylbowman I did that with my rpx, I would be great that the Report Designer could support this kind of paper.

I agree that it would be nice to have a more elegant approach.
