My printer doesn't print A3 papers correctly (HP OfficeJet Pro 7740)

[Emanuele18]

Hi
I'm having some troubles while trying to print A3 documents; the horizontal lines are printed like this "////" instead of this "____". Although, when I use my phone to print A3 PDFs, i have no problems, the documents are perfect. What could be the problem?

My OS is WINDOWS 11

Welcome to the HP English Community --

Check both of the following on the Windows system:

• The Full Feature Software / full driver printer software must be installed.

and

• The HP Driver must be selected in Printer Properties as opposed to the Windows / IPP Driver set.

What?  Windows print drivers do not do well with A3 printing.

==================================

Printer - Full Feature Software

HP Full Feature Software / Full Driver printer software - supports printing and scanning from the web, printing in in other software and programs (for example, Word), and provides access to the full range of Printing Preferences / Shortcuts.  The full driver generally adds at one, possibly least one, possibly two shortcuts to the Desktop: Printer Assistant, HP Scan Assistant, and/or HP Scan.

NOTES:  

HP Scan is not installed if the printer does not support Scan.

The Printer Assistant is not installed if the type of full driver software does not support it.  If the printer model includes built-in Fax hardware, the software supports the setup and use of the Fax driver. No Sign-in required.

Reinstalling?

• Uninstall existing full driver printer software from Programs and Features.
• If your printer includes a separate "help" in Programs and Features, uninstall that, too.
• Restart the computer and log in.
• If the printer is connected to the computer using a printer USB cable, remove / disconnect the cable before loading the software.

If / When asked, opt for the Full Driver / Full Software to be installed.

After the software is installed, Restart the computer and sign in.

The installation of the full driver generally adds at least one or more shortcuts to the Desktop.

 Note:  Printer Assistant, HP Scan Assistant, and HP Scan are dependent on printer model and supported software options.

• Printer Assistant – Where still supported as part of the full driver printer software
• HP Scan Assistant – For those printers that no longer provide the Printer Assistant
• HP Scan – Shortcut on Desktop named for the printer model
• When installed, HP Universal Scan software adds a separate self-named “HP Scan” shortcut

Printer Assistant shortcut > Tab Scan > Manage Scan to Computer > Enable

Or

HP Scan Assistant shortcut > Manage Scan to Computer > Enable
