Windows 10: HP 400 Laser Printer-duplex and paper size errors

1. My HP 400 won't print double sided lately for docx documents.

2. It also wants legal paper inserted for a letter-sized Word document that it says has text outside the margins but it also says text is very close.

3. It pops up an error message when I attempt to print the docx document saying "Printer HPLJ300-400 color M351j-M451 PCL6 does not exist on the computer."

Printer's default paper size ignored

I often print to PDFs. My PDF printers are set to a default paper size of Legal. But when I print the size is Letter and I have to change it each time. This used to work. I'm not sure when it changed.

• Windows Setting Manage Default Printer is not checked
• Doesn't matter which printer I use - PDFCreator, Bullzip PDF, Adobe PDF
• Windows 10 build 1803
• Happens when printing from many apps - Microsoft Office, LibreOffice, Email
• Works properly when printing from other apps - Notepad, Notepad++, browsers
• Happens on multiple computers - desktop and laptop

Any tips on how to get the printer default paper size to work?

 

How do you auto-duplex on HP m277dw printer with Windows 10?

Various forums suggest setting the Duplex Unit to Installed on the Device Settings dialog to get the HP m277dw printer to print double sided. I have done this and it works if I manually flip the pages:





This model printer has allowed for automatic duplexing for versions of Windows prior to Windows 10.

What can I do to cause the printer to auto-duplex under Windows 10, whether that's a setting on the printer itself, a driver update, or some obscure Windows setting? HP Support doesn't seem to know what to do.

 

Wireless Printer Will Not Duplex Print

I'm not sure this is a Windows problem. It may be an HP problem but I've not been able to get a solution on their forum so here goes a try on this forum

My HP Envy 4520 wireless network printer will not duplex print when installed on my HP Pavilion Notebook. The printer will not give me the ability to duplex print automatically. Printer preferences shows only 2 sided manually and that requires me to manually remove paper, turn it around and insert it in the printer. A pain in the neck for I do a lot of multi-page printing.





I will really appreciate help.

Oh, by the way the printer works fine on my Del Desktop.

Thank you very much.
