// Because, for this document, our printer setup - a Brother P-touch QL-500
// label printer driven by a CUPS with the printer-driver-ptouch - and
// DK-11208 Large Address Labels (38x90mm), either the printer driver or the
// printer itself doesn't properly print on the labels, we need to deploy some
// workarounds using margins.
// Link to the printer-driver-ptouch:
// https://github.com/philpem/printer-driver-ptouch
//
// For the horizontal margins, we use a 4mm margin on the left and a 0mm
// margin on the right.
// Do this because by default the print itself is offset to the left sadly. It
// seems like the printer is printing from the very edge, where the label
// roll, but not the label itself, is. On the label roll on the left there are
// 2mm of material until the label itself starts, so we need to offset by 2mm
// on the left for the print to be on the label itself. However this offset
// also results in a forced margin of 2mm on the right, so to have an even
// margin on the resulting label, add another 2mm of margin on the left,
// resulting in 4mm of margin on the left in total. Also just don't have any
// margin on the right, since there's a forced margin already anyway.
//
// For the vertical margins, we use a 0mm top margin and a 9mm + 9pt bottom
// margin.
// Do this because the printer doesn't print from the very top of the label
// sadly, so since we then have a forced margin there anyway (one of 6mm), we
// don't need to add any top margin.
// On the bottom, we already need a margin of 9pt for the image to be fully on
// the page. However, because the printer doesn't start at the very top, the
// printing ends after the label already ended. To combat this, add a margin
// of 7mm for the logo to still be on the page and add another 2mm for the
// margin to be same as the margin at the sides (resulting in 9mm).
//
// These workarounds were developed for this document, our Brother P-touch
// QL-500 label printer in combination with DK-11208 Large Address Labels
// (38x90mm).
