Root cause of the oversized/wrapping text on the printed slip: ePOS-
Print XML's <text> attributes (width, height, em) are stateful on the
printer — they persist across subsequent <text> tags until explicitly
changed back, not per-tag like CSS. The sale slip's header_title block
sets width="2" height="2" for the big title and nothing after it ever
reset back to width="1" height="1", so the entire rest of the receipt
(business info, items, totals, payment, footer) inherited double-size
text — exactly the wrapping/misalignment seen in the photo. Same
issue existed in the delivery note (header's height="2" leaking into
every line after it) and cash-up (GRAND TOTAL's em="true" leaking
into CASH RECONCILIATION's non-bold lines).
Now every <text> tag in all three XML builders explicitly declares
width/height/em rather than relying on inheritance from whatever
tag ran before it. This isn't just a display fix — since blocks are
now user-reorderable/toggleable, no block can safely assume what
state a neighboring block left behind; every block must be correct
in isolation regardless of order.
Same class of bug existed on the Bluetooth ESC/POS side: ESC/POS's
alignment command is equally persistent, and the sale slip's
header_title centered the title but relied on the next block
(business_info) to reset it back to left — broken the moment
business_info is disabled or reordered. Fixed the same way: each
block resets what it changed before returning.
