How do I check the ink levels on my HP Photosmart 7350 inkjet printer under Windows 7?

If you are running Windows 7 I believe it has been disabled. There are some work arounds but I'm not sure.

To check the ink levels from the printer control panel
1. Press Setup.
2. Press the down arrow button to highlight Tools, and then press OK.
3. Press the down arrow button to highlight Display Ink Gauge, and then press OK.
The product displays a gauge that shows the estimated ink levels of all cartridges
installed.
4. Press any button to return to the Tools menu.
To check the ink levels from the HP Photosmart Software
1. In the HP Solution Center, click Settings, point to Print Settings, and then click
Printer Toolbox.
NOTE: You can also open the Printer Toolbox from the Print Properties dialog
box. In the Print Properties dialog box, click the Features tab, and then click the
Printer Services button.
The Printer Toolbox appears.
2. Click the Estimated Ink Level tab.
The estimated ink levels for the ink cartridges appear.
Replace the ink cartridges

1. Open the Printer Toolbox . There are two ways to do this:
   • Open HP Solution Center , select Settings , and then Printer Toolbox .
   • If the HP Solution Center method does not work, open Printers and Faxes in the Windows Control Panel, then right-click the printer icon and choose Printing Preferences . Click the Features tab, and then click the Printer Services button.
2. The Printer Toolbox opens. Click the Estimated Ink Level tab. A cartridge may be running out of ink even if the graphic shows otherwise. (see the note at the start of this section). Lines or streaks always appear in printouts when the cartridges begin to run out of ink. Replace print cartridges that are out of ink or low on ink.

Assuming you have all the HP drivers installed:

3. From the HP Solution Center , click the Settings menu.

You need the HP Toolbox software: Follow these steps to check the ink levels in the Toolbox . The Toolbox is part of the standard printer software. Depending on the version of Toolbox on your computer, the appearance of the Toolbox features might vary. NOTE: Ink level warnings and indicators provide estimates for planning purposes only. When an indicator shows low ink levels, consider having a replacement cartridge available to avoid possible printing delays. Print quality deteriorates as cartridges run out of ink.

Or

Print a self-test report
1. Load A4 unused plain white paper into the input tray.
2. Press and hold the Cancel button and then press the Start Copy Color button.
The product prints a self-test report, which might indicate the source of the printing problem.
3. Make sure the test patterns show a complete grid and the thick color lines are complete.
• If more than a few lines in a pattern are broken, this might indicate a problem with the nozzles. You might need to clean the print cartridges.
• If the black line is missing, faded, streaked, or shows lines, this might indicate a problem with the black or photo print cartridge in the right slot.
• If any of the color lines are missing, faded, streaked, or show lines, this might indicate a problem with the tri-color print cartridge in the left slot.

In your HP software "Toolbox" click the "Estimate Ink Level" tab.

To get to the HP "Toolbox"
Click Start > Control Panel > Printers
Right click your printer name, choose "Preferences"
Click the "Services" Tab
Click "Service this Device"
The Toolbox opens

You should have an HP Toolbox icon (Windows) on your desktop or in your Programs list. Open this and find the tab that says: Estimated Ink Level. Your printer has to be connected to your computer for this to work. Be aware these are estimates only. It's always good to have a spare cartridge or two on hand, especially if you do a lot of photo printing.
