Can't Print #10 Envelope Correctly

I recently switched to using LO (v7.6) on Win10 and am not able to print out a #10 envelope on my Canon printer MX870 with the correct orientation and font size – despite making sure I have the correct selection of page size and orientation.

[Note – the two sets of lines were results of two attempts].

It seems that LO stubbornly sticks with portrait orientation and scales the font size to fit its conceived paper width.

can that help?

Envelope in Writer

Thanks for the pointer.

I did go through all the steps that are in that write-up, but to no avail.

You may want to check your printer manual to see how envelopes should be inserted. In most cases, envelopes have to be inserted manually in the feed tray.

Before switching to LO, I had printed envelopes of various sizes on this same printer with MS-Word of various vintages for years without any difficulty/issue.

This is quite an old old bug:

tdf#106831

Thank you, as I was going crazy thinking I missed something trivial!

It seems from the bug-report thread that the bug got fixed and unfixed.

I can’t remember a time where every envelope size printed correctly on LibreOffice, or even with OpenOffice.org and StarOffice before it. There has always been some kind of envelope printing issue, whether it was orientation, page style, text frame size, etc. Given the wide range of printers, drivers and supported operating systems, this isn’t really surprising, but of course, when it affects you in your daily work and it just works with the market leading product, it is incredibly frustrating.

Have you tried setting the envelope size and orientation in the printer driver not just in the LibreOffice print window? I need to do that when printing envelopes from Word so it might be a print driver thing.

See canon site which warns of possibility of orientation issues, Canon Knowledge Base - Loading Envelopes - MX870

The printer-driver settings direct dialog is the same as that provided from within LO and yields the same incorrect result.

We know that it is the printer driver that is scaling the font size from screenshot 3, so you might like to untick that setting.

Did you try keeping all the settings the same but changing orientation to portrait? Or not setting the LibreOffice settings at all (on a new document) but making changes only in the print driver, the LO print dialogue and the printer driver might be rotating the document to compensate for the three others setting, I get this with booklet printing…

I found out that while fiddling with LO Print settings I had been too focused on the “Printer Properties” settings while overlooking the “Page Layout” settings in the “General” tab. With the correct settings selected – #10 Envelope & Landscape – the issue was resolved.
