Recent answers to When print letter, prints as 4" wide.

</p><p>Then I remembered seeing a setting paper_width...the Zebra and this same HP were 4.25, all of the other printers were -1. I left the others alone for now and changed the Zebra to 4.00 and the HP to 8.50 as that is what they should be.
</p><p>For S&amp;G, I then looked at paper_height, and the Zebra and this HP was set to 11, and all the others were -1. I changed the Zebra to 1 and left the HP and others alone.
</p><p>Ran a test. Both this HP and one of the other printers is fine, but the Zebra is a bigger mess now. I put the Zebra back to where it was, and it is at least usable.
</p><p>The site I print the labels from was designed around IE and ScriptX. MOST things print fine in FF, except for one label (which is an important one). This discussion allowed me to fix MY issue (the letter sized paper)... I will check with the ERP people about the labels to see if they know what is going on there as I don't think that is a FF issue.
</p>Hmm, why is the label width being applied to a different printer? I haven't heard of that one before2019-12-17T09:51:07-08:00jscher2000https://support.mozilla.org/en-US/questions/1275261#answer-1274380<p>Hmm, why is the label width being applied to a different printer?

</p><p>Let me start with something more general:
</p><p><em><strong>Firefox Using One Corner of the Page</strong></em>
</p><p>One reason for Firefox not to use your entire piece of paper is if it misread the printer data and thinks it holds very small paper. As a possible quick fix, try this:
</p><p>(1) In a new tab, type or paste <strong>about:config</strong> in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.
</p><p>(2) In the search box above the list, type or paste <strong>paper_data</strong> and pause while the list is filtered
</p><p>(3) This value varies, but based on past threads:
</p>
<ul><li> 1 means letter size
</li><li> 9 often means A4 size
</li><li> 256 is an unknown small size that sometimes shows up on Brother printers for no apparent reason
</li></ul>
