• How to print multiple receipts or invoices on one page — Drag PDF invoices, receipt photos and payment screenshots into one tool and they are laid out at real size on A4 sheets, ready to print.
• How to print multiple pictures on one A4 page — Add several photos or screenshots and they are arranged on one A4 page, uncropped and as large as possible, ready to print or save as PDF.
• How to print text messages and chat history — The easiest way to print a conversation is from screenshots. Add them to the tool and long ones are split into readable columns on A4 paper.
• What DPI do you need for printing? — DPI is dots per inch. For text and photos, 300 DPI prints sharp and 150 DPI looks a little soft. Exports from the layout tool are already 300 DPI.
• How to print a long screenshot so you can read it — Shrinking a long screenshot onto one page makes the text unreadable. Split it into columns instead; the tool cuts between lines and adds pages as needed.
• Why does my printout come out the wrong size? — Prints that come out slightly small or cut off are usually caused by "Fit to page" scaling or the wrong paper size. Set Actual size / 100% and test.
