Hi kupdike2000, sorry to hear that you are facing this problem.

You can add an add-on to the browser that allows you to print any Web page or browser tab as a PDF document.

Install PrintPDF

Step 1. Launch Firefox and navigate to the Mozilla Web page that offers the free PrintPDF add-on (see Resources). Step 2. Click 'Add to Firefox," click the "Install Now" button when it appears and then click "Restart Now" to restart the browser. Step 3. Navigate to any Web page after Firefox restarts and click "File." Select "Print to "PDF" and type a name for the file you are about to create in the "File Name" text box. Step 4.Click "Save." The add-on prints the Web page to the PDF file you designated in the "File Name" text box.

Use Print Pages to PDF

Step 1. Visit Mozilla's Print Pages to PDF add-on Web page (see Resources) and click "Add to Firefox." Step 2. Click "Install Now" and wait for the "Restart Now" button to appear. When it does, click that button to restart Firefox. Step 3. Visit a Web page and right-click that page. Click "Print Pages to PDF" to view a menu containing print options. These options are "Print Active Tab," "Print Active Tab (Text)," "Print All Tabs" and "Print All Tabs (Text)." Step 4. Select the desired print option. The add-on prints the content you selected and displays it in your PDF reader. If you select one of the "Print All Tabs" options, the add-on combines all tabs into a single PDF. Choosing one of the options that has "Text" in the name causes it to only print text from Web pages. You can also right-click a tab or bookmark to view the menu that contains print options.

If it doesn't solved your problem feel free to ask in Reply Section. Thanks for raising your question in Mozilla Support Forum.

Thank you for your prompt reply. I prefer not to install any add-ons. Is it possible to use the Windows 10 built in PDF print? This is available to all programs on Windows 10 to print to PDF. The way I access it is from the File Menu, select Print, then I select printer "Microsoft Print to PDF" as the printer. This works perfectly with Internet Explorer and other applications on my computer. It is only with Firefox that it does not print the document in it's entirety. Thank you for your help.

Hi kupdike2000,

You may wish to reconsider your aversion to installing a new application to handling the conversion to PDF documents. I find that the 'Microsoft Print to PDF' does not always play nice with non-Microsoft applications. For years, I have been using the free version of PrimoPDF which you can download from https://www.primopdf.com/

It installs as a virtual printer and will show up in the list of printers when you "File | Print..." from almost any windows application. It will 'print' to a selectable folder on your computer, which can then be printed out on paper, if you desire.

I use PrimoPDF exclusively as my PDF maker. It has many nice features, I especially like the ability to -- extract pages from -- or add pages to -- an existing PDF file. It is also possible to combine several PDF documents together.

Thank you both for your input. It is much appreciated. I will try it out.

Hi kupdike2000, often a problem you see in a PDF will appear in Print Preview. In other words, it is a problem with how Firefox is laying out the page for printing and it's not specific to a particular printer.

There are numerous style rules that Firefox can display properly on screen (continuous) but is unable to split across page boundaries correctly. For example, the content may just run off the bottom of the page. There is work ongoing this year to correct that problem, but I don't know how soon it will roll out. Maybe this Fall?

I personally print PDFs a lot so I created an add-on to tweak pages to work around some of these issues. If you're interested. Please check the screenshots on the Add-ons site for more info:
