Canon Fax L140 Printer Driver May 2026

| Setting | Recommendation | Why? | | :--- | :--- | :--- | | Print Quality | 600 dpi (Standard) | The FAX L140 maxes at 600x600 dpi. “1200 dpi” just interpolates and slows print speed. | | Toner Save | On | Reduces toner usage by 30-40% for draft documents. | | Page Layout | 2-in-1 or 4-in-1 | Great for saving paper when printing long manuals or drafts. | | Grayscale Processing | Black and White (Pure) | Never set to “Color” – the L140 is monochrome only. | | Bindings | Long edge or short edge | Crucial for double-sided (duplex) printing if your model supports it (the FAX L140 requires manual duplex). |
