A human preparing a document photo usually has a simple goal: one clean file that survives the next screen in the application. The advice below is organised around that goal.
Design the output around the paper
For physical photos, the paper is the canvas. Decide the finished photo dimensions, number of copies, spacing and safe margins before exporting the sheet. Then make sure the print dialogue does not rescale the page.
A small test prevents a large reprint
Measure one printed copy after the first run. If it is larger or smaller than intended, stop and correct the scale setting before printing the entire sheet. “Fit to page” is convenient for ordinary documents but can change the physical size of an ID photograph.
Build the A4 sheet deliberately
A4 is 210 × 297 mm. Treat those paper dimensions as fixed, then place the document photos inside the page with margins and spacing. Do not calculate the number of copies from a screenshot; calculate from the actual photo and gap dimensions.
Print at 100%
Disable “fit” or “shrink to printable area” when exact physical dimensions matter. If the printer cannot print edge-to-edge, keep the layout inside the printer’s safe margins.
For a time-sensitive application
Download or save the final file before closing the session and note the destination next to its filename. That small bit of housekeeping matters when several applications are being prepared in the same week.
The physical result deserves its own quality check
When the final output is a print sheet, check one physical copy rather than trusting the preview alone. A printer can introduce scaling, border expansion or colour shifts that are invisible in the exported PDF or JPEG. A small ruler or a known reference measurement can confirm the actual dimensions before you produce the full batch.
The part worth saving
Treat the prepared file as a deliverable with a destination. A clear filename, current requirement and preserved original make the workflow much easier to audit or repeat.
