The module-scoped `pendingPromise` in `webContents.printToPDF` was chained with `.then(onFulfilled)` and never cleared. Once a call rejected (e.g. an out-of-range `pageRanges` like `"999"`), subsequent calls chained onto the rejected promise and short-circuited without ever invoking `_printToPDF` — so every following call re-surfaced the original error. Replace the shared variable with a per-`WebContents` `WeakMap` queue that swallows prior rejections before chaining and clears its entry once the tail drains.
