Set the paper first
A4 versus Letter is still the silent killer of international files. Writer: Page Layout → size, then Print Preview at 100 percent. If a heading kisses the footer, it will kiss the physical margin too. Spreadsheets: set print area, Fit to width (usually 1 page wide, as many tall as needed), and check page breaks in Page Break Preview — not in the grid.
Duplex and binding
Enable duplex in the printer dialog, not by hoping. For a bound thesis, add a gutter in Page Setup. Mirror margins on odd/even pages if you are printing a booklet. WPS booklet options vary by build; if the control is missing, export PDF and impose in a dedicated tool or at the copy shop.
Spreadsheets that become 40 pages of 8-point type
That is not a printer bug. Hide unused columns. Repeat header rows on each page. Landscape a wide table. If the audience only needs a chart, print the chart — not columns A through AH. Sheets notes · formulas.
Labels and envelopes
Match the product code (Avery or local). Print one sheet of cheap paper, overlay on the label stock against a window, then commit. Mail merge details: mail merge.
Presentation handouts
Export PDF. Choose 2 or 3 slides per page if you are saving trees. Animations die on paper; that is the point. Carry the PDF on a USB in case the room PC has no WPS. Slides.
When the driver is the villain
A school HP that still has a 2014 driver will ignore duplex and scale to 94 percent for fun. Print to PDF first, then print the PDF from a viewer the lab already trusts. If WPS Print Preview looks right and paper looks wrong, it is the driver or the tray — not Writer.
