Why Print to PDF Breaks an Online Textbook's Layout

Pressing Command+P on an online textbook rarely gives you clean pages. Figures vanish, tables split across pages, the reader's toolbar repeats on every sheet, or the PDF is blank after page one. The cause is almost always the print route, not your printer settings.

This post shows how to choose the right route, read the symptom, and avoid spending a limited print allowance on bad output.

Start with the right print command

An online reader is a web app. The browser's own print command prints the app's screen layout, which was never designed for paper. The reader's print button sends a print-ready version of the pages you select.

Route	What it prints	Typical result
Reader's print button	The publisher's print version of selected pages	Clean pages, counted against the allowance
Browser File, then Print	The visible web page and its interface	Cropped, blank or broken layout
macOS PDF menu in the print dialog	Whatever the chosen route sent	Matches the route above it

Use the reader's print button. Then, in the macOS print dialog, choose the PDF menu and Save as PDF if you want a file instead of paper.

Diagnose the visible symptom

• Blank pages after the first: the browser printed only the visible viewport of a scrolling reader.
• Missing figures: images had not loaded yet, a pattern known as lazy loading.
• Toolbar on every page: the browser route printed the app interface.
• Tables split mid-row: the print stylesheet does not keep table rows together.
• Repeated headers or page numbers: the reader adds its own header and the browser adds another.
• Tiny text: the reader's page was scaled to fit a wide screen layout.

The first three point to the wrong route. The last three can often be fixed in settings.

If browser preview is missing content, load one permitted sample

When you must use the browser route, for example for a free chapter or course page with no print button, load the content before printing:

1. Scroll slowly through the pages you will print so every image loads.
2. Wait a few seconds at the end.
3. Open print preview and check one page with a figure.

Test with one short, permitted sample first, rather than a full chapter.

Check print settings in this order

1. Destination: the reader's print, then the macOS PDF menu.
2. Pages: the exact page range, not "All".
3. Paper size: match your region, such as A4 or US Letter.
4. Scale: fit to page width, or 100% if text is already readable.
5. Headers and footers: turn off the browser's own if the reader adds them.
6. Background graphics: turn on if highlights or shaded boxes are missing.

Check the preview after each change.

Avoid wasting a limited print allowance

Many readers count each printed page against an allowance, whether it goes to paper or a PDF. The allowance for your title appears in the reader or in your account.

• Print only the pages you need for the current week.
• Combine short ranges into one job where the reader allows it.
• Keep the saved PDF so you do not print the same pages twice.

When screenshots are a valid fallback

Screenshots are a fallback only when you are allowed to keep the pages and the print route cannot produce a usable layout. Examples are your own course pages, an open-licensed book in a web viewer, or a reader that offers no print at all for content you have rights to copy.

In that case, Temposhot captures each visible page as an image and exports a searchable PDF in page order. The ebook pages to PDF tutorial shows the setup, and screenshot PDF vs browser Save as PDF compares the two outputs. Screenshots are not a way to print beyond an allowance, and Temposhot cannot capture a reader that blocks screen capture.

What to send support

If the reader's own print route still breaks the layout, contact the platform's support with:

• The book title, edition and ISBN.
• The page range you printed.
• Browser name and version, and macOS version.
• A screenshot of the print preview showing the problem.
• Whether pages were deducted from your allowance.

Ask whether they can restore the deducted pages after fixing the issue.

FAQ

Why does the reader's print button open a new tab

Many readers render a print version in a separate tab, then open the system print dialog. Print from that tab.

Can I fix a broken PDF afterward

You can remove blank pages or reorder them with PDF Page Organizer. Missing figures cannot be added back.

Does Save as PDF keep text searchable

From the reader's print route, usually yes. From a browser route that printed images of the page, often no.

Working with pages you are allowed to save?

Capture them as images and export a searchable PDF with Temposhot. The save screenshots as PDF page shows the workflow.
