Hi @MJDodd,
Welcome to the HP Support Community!
Thanks for reaching out about your query regarding printer settings!
We're thrilled to have the opportunity to assist you and provide a solution.
The HP OfficeJet Pro 7740 typically displays paper size in inches by default, but you can change the settings to millimeters (mm) in the printer preferences. Follow these steps:
Method 1: Change Paper Size Settings in Windows
- Open Control Panel → Devices and Printers.
- Right-click on HP OfficeJet Pro 7740 → Click Printing Preferences.
- Go to the Paper/Quality tab.
- Click on Advanced.
- Look for Paper Size and select Custom.
- Set the dimensions in millimeters (mm).
- Click OK and Apply.
Method 2: Change Printer Language to Metric (if supported)
- On the printer’s control panel, go to Settings.
- Select Preferences or System Setup.
- Look for Units of Measurement (if available).
- Change from inches to millimeters (mm).
- Save the changes and restart the printer.
Method 3: Change Paper Size in HP Smart App
- Open HP Smart App on your computer.
- Click on your printer → Printer Settings.

If your printer still does not display mm, you may need to manually input paper sizes in custom settings.
