Firefox

Firefox is very easy to set up for printing use in our system. The first thing you will want to do is bring up the menu items for Firefox, so if you don't already see them at the top of your screen, hit your Alt key once, and they will pop up for you.

 

In the Page Setup window, first make sure that the scaling is 100% and the checkbox is checked, and in almost all cases, you will be using Portrait orientation. Don't click OK just yet, one more step after this one:

Next, click on the Margins & Header/Footer tab. In here you will want to zero out all of the Margins, and click on each of the buttons for Headers and Footers and change them to make sure they all say Blank. When you are done, your window should look like this:

Click OK and you're all set!

You may periodically need to come back in here and make these settings again. Firefox periodically updates itself, and the updates, at least for now, reset this window to the defaults. You will know when this happens if you see extra space around what you are printing and extra information at the top and bottom of the print for things such as the web page URL, date and time, etc.


Advanced Printer Setup in Firefox

 

"I set my default printer for Windows but whenever I print from Firefox it uses a different printer. How do I make it print from the one I want?"

 

How to Set Your Default Printer in Firefox

PLEASE NOTE: The About:Config area of Firefox allows you to control how it interacts with your printers. Be very careful to only change the settings we recommend, proceed with caution in researching and making any other changes!

Here are the steps to set your default printer in Firefox:

  1. In a blank Firefox window, in the Address Bar where you enter website URLs (NOT in the smaller Search field on the right), enter the following: about:config
    Then hit your Enter key. You will see the following warning:

  2. This statement is misleading, and it's kind of a little joke by the team at Mozilla, the makers of Firefox. Firefox has no warranty to void, and while it does offer control of how it interacts with your other hardware, there isn't anything in there that could possibly void a computer warranty or a warranty on a printer. We recommend that you click to un-check the Show This Warning Next Time box and then click the I Accept the Risk button.
  3. Next, enter the following in the Search area to get to the default printer setting for Firefox: print_printer

    print_printer_default_reset.png
  4. In the Value column on the far right, right-click on the printer name and a menu will pop up. In the menu, click Reset. You will see the printer blank out.
  5. In the last step, you will go to your Cloud Based Point Of Sale system and print from the printer you want to be the default. Firefox will make that printer the default and fill in the blank in its settings.
  6. Double check by going back to about:config, and in the search line enter print_printer. You will see the printer you just printed from as the default.

 

 

 

I have set my paper size properly in the printer driver, but whenever I print from Firefox it uses the wrong size! How can I set it to use the correct size?

 

How to Set Default Printer Paper Size in Firefox

PLEASE NOTE: The About:Config area of Firefox allows you to control how it interacts with your printers. Be very careful to only change the settings we recommend, proceed with caution in researching and making any other changes!

Here are the steps to set your default paper size for a printer in firefox:

  1. In a blank Firefox window, in the Address Bar where you enter website URLs (NOT in the smaller Search field on the right), enter the following: about:config
    Then hit your Enter key. You will see the following warning:

    warning.png
  2. This statement is misleading, and it's kind of a little joke by the team at Mozilla, the makers of Firefox. Firefox has no warranty to void, and while it does offer control of how it interacts with your other hardware, there isn't anything in there that could possibly void a computer warranty or a warranty on a printer. We recommend that you click to un-check the Show This Warning Next Time box and then click the I Accept the Risk button.
  3. Next, enter the following in the Search area to get to the default printer setting for Firefox: print.printer (please note, this is different from the above command for default printer, print_printer, so they are easy to confuse).
  4. You will see a list of all printers used by Firefox. Scroll down until you find the exact model you want to work with for setting paper size. Please note that you may have multiple copies of the same printer, so you need to find the same exact one, for example, Epson T88 V copy 2 might be the one you actually prefer to print from.

  5. In the image above, you can see the three areas we will be resetting: paper height, paper width, and there is a chance you will want to reset your paper size unit. In the example above, our Epson printer uses millimeters instead of inches for paper size, but the settings are currently in inches. For paper_size_unit, the setting is currently at 0, which is for inches, so it will need to be reset.
  6. Right-click the number in the Value column for paper_height and in the popup menu, click Reset. You will see the number blank out.

  7. Right-click the number in the Value column for paper_width and in the popup menu, click Reset. You will see the number blank out.

  8. If you need to reset the paper size unit, right-click the number in the Value column for paper_size_unit and in the popup menu, click Reset. You will see the number blank out.

  9. Now that everything needed is reset, we need to do a follow up print to update the settings from the printer driver. So go to your Cloud Based Point Of Sale system and print to the exact printer model you just reset.
  10. Last, we need to go into the Firefox settings again and make sure the browser knows to always look at the driver settings, so once again, go back into about:config, and this time, in the Search line, enter the following: print.save_print_settings
  11. In the Value column, right-click on the word true and in the popup menu, click Toggle. You will see the value change to false.
