A small guide to getting started

How to Print Coloring Pages

Print a library picture or your own converted photo on the paper you have. Start with the kind of image you want to print, then check the sheet before using ink.

A picture from the library

  1. Open any coloring page and choose A4 or US Letter.
  2. Select Print this page to open a clean print sheet. Wait for the image to load, then press the print button.
  3. Before direct printing

    Even if you choose US Letter on ColorWillow, the print dialog may still default to A4. Check Paper size in the dialog and change it to Letter before printing.

  4. Check the preview shows one page with the whole drawing visible before printing.

Save a PDF for later

Choose a paper size on the coloring page and select Save as PDF. The PDF is created in your browser using the original PNG, centered on one sheet with the same safe margin.

Before direct printing

A downloaded PDF or PNG

PDF

  1. Open the PDF in your PDF viewer and choose the matching paper size.
  2. Start with Actual size or 100%. If the preview clips any part of the drawing, use Fit to printable area and check again; this may make it a little smaller. Avoid Fill or borderless enlargement when they crop the image.

PNG

Open the original downloaded PNG in your image or printing app. Choose the paper size, then Fit to page with the full image visible. Keep its proportions and avoid crop-to-fill. The website’s paper choice does not set the paper size in that other app.

Match the paper in your printer

For US Letter paper, choose Letter (8.5 × 11 in). For A4 paper, choose A4 (210 × 297 mm). Check both the website and the print dialog; they can have different defaults.

Actual PDF previews: the same square flower drawing, centered on one sheet in each size. Open a sample to check the page layout before printing.

Why is there white space around the drawing?

Dashed line: 10 mm safe margin

This Letter preview uses the same image and layout as the downloadable sample. The dashed guide marks the area inside the page’s 10 mm (about 0.39 in) safe margin.

A square picture leaves more space above and below it on a portrait sheet. The image keeps its proportions; that extra space does not mean part of it is missing.

The dashed guide is only shown here. It is not printed in the sample PDF. Check your printer’s preview too, because its printable area may differ.

  1. Choose “Add to list” on a picture card. Open the print list to remove pictures or change their order. The list stays in this browser tab, expires after 30 minutes without print-list activity and holds up to 10 pictures.
  2. Choose A4 or US Letter and decide whether to include a cover. Select Print to prepare every picture before the browser’s print dialog opens. A cover adds one sheet.
  3. You can also download the whole list as one PDF. Canceling preparation or closing the print dialog keeps your list so you can try again.

Open your print list

Use the print list for a quick one-picture-per-sheet PDF, with an optional cover. Choose Add to book draft when you want page text or more control over the cover and order. The list stays intact. For a ready-made sequence, start with a book from the coloring book library.

How to make and keep a book

If the print preview does not look right

The edges are cut off or the picture is too small

Use the same paper size on ColorWillow and in the print dialog. For direct printing, choose 100% scale, no extra margins, and turn off headers and footers. The sheet already has a safe margin. If you print the downloaded PNG in another app, use Fit to page instead.

A sheet is blank or there are extra pages

Wait until the pictures finish preparing. Check the preview page count: one sheet per picture, plus one if you selected a cover. Check paper size and margins. If a picture fails to load, cancel, check your connection and retry; you can remove the named picture from the list.

The print dialog does not open

Try the Print button again after preparation finishes. If your browser still does not open a print dialog, download the PDF and print it from your PDF viewer. Check its preview and paper settings before printing.

A note on clarity

A PDF sets the page layout; it does not add image detail. Use the original download, not a screenshot. For Free results, 1024 px can retain more detail than 512 px but takes more memory and requires another conversion; small source photos are not enlarged. If lines still look soft, reduce the print size in your printing app or choose a clearer source.
