TEST TWO DISTINCT SHEETS
Manual duplex printing helper
Check refeed direction and order with two labelled sheets. Your printer is not detected automatically.
01 · Test with two sheets
Session not checked yet. Without a source session, only test sheets are available.
SHEET A/B, two physical sheets, are needed to check order. Before loading, mark one side lightly in pencil and record how you loaded them.
Compare TOP, corners 1–4 and front/back labels. Test the back using the same refeed method.
02 · Confirm what you observed
| Order | Front | Back |
|---|
One sheet cannot establish stack order
One sheet shows only the printed side and direction. If A/B pairing is unclear or printing lands on the wrong side, document export stays locked. Test the four combinations: same/reverse order × back 0°/180°. No automatic inference or mirrored text is supported.
Check batches of up to 16 sheets. Recheck a batch after a jam or double feed. Retest when settings change. If a 100 mm line measures differently, first check 100% printing. Scale, offset, skew and paper shrinkage are not corrected automatically.

Privacy and file handling
PDF processing and previews run in this browser. Document files, names, contents and metadata are not sent to a server or saved in browser storage. There are no ads or third-party scripts in the processing area. Static-site access may still produce server logs.
Your original is unchanged. Output is for printing; link, bookmark, accessibility-tag and signature preservation or secure removal of hidden data is not guaranteed. Even a small scanned file can use substantial memory. Physical-printer and all-browser validation are not claimed.
