Three corrections from the first real session. Routed via a manager, the box
was prefilled with the DX's own address — the one thing that must not go on
that envelope. It now starts empty and the QRZ fetch fills in the MANAGER's;
switching the routing recomputes the box unless the operator has typed in it,
because a hand-checked address is not the app's to replace.
A fetch that came back with no street was overwriting a reviewed address with a
bare country — the cty.dat fallback dressed as an answer. It now refuses to
touch the box and says nothing was found. And the prefill no longer stacks the
same town three times (address + QTH + country all carrying it).
The output is ONE PDF for the whole session, each page at its own label size,
written to the temp dir and opened straight in the viewer — no save dialog: the
file is a print run, not a document to keep.
The printing session in three steps. The worklist is the paper queue (ADIF
qsl_sent R/Q), grouped by callsign since several QSOs of one station share a
card. Each recipient is reviewed before anything prints: routing first — via
manager when qsl_via says so, direct when an address is known, bureau otherwise
— then the address itself, editable and fetchable from QRZ (the MANAGER's
address when routing says via). What is printed is the reviewed text verbatim,
not a re-resolution that could differ from what was checked.
One PDF per label kind, never one file for all: a roll printer holds one stock
at a time, and a file mixing 29 mm addresses with 62 mm QSO labels could not be
printed at all. Pages are rasterised by the designer's own renderer at the
stock's dpi and carried into the PDF untouched — internal/pdf is a hand-written
image-page writer (DeviceGray + flate: monochrome, lossless, no cgo) because
that is the entire need.
Bureau stations get no address label (no envelope); return labels are printed
one per envelope. Finishing offers the log update: QSL_SENT=Y, the chosen date,
via B or D per routing — through the same BulkUpdateQSL the paper view uses.
A fixed 720 px cap cut a 98 mm label off at the RST column and wasted half the
window; the scale now follows the centre pane's measured size, with a floor so
small stock never renders unreadably.
The designer's data model lives in internal/labels: STOCKS are the physical
roll in the printer (geometry in mm, margins, dpi — seeded with the common
Brother DK sizes, the QL family being what prompted the feature), TEMPLATES are
one design each, of two kinds: the QSO label glued on the card, whose repeating
table carries several contacts of the same station, and the address label for
the envelope, whose lines collapse when a variable is empty.
Everything is measured in millimetres — labels are sold in mm, and an operator
lining a design up against a physical sticker thinks in mm; pixels exist only in
the renderer, at the stock's dpi. The canvas renderer is shared between the
editor's preview and the future print path, so there is no second
implementation for the preview to disagree with.
The preview is fed with the log's latest contacts rather than lorem ipsum: real
data shows a too-narrow column immediately.
Printing (PDF, one page per label at exact size) is the next module; nothing
here prints yet.
