Where to find your ink levels on the printer itself
The fastest way to check ink is usually right on your printer. Most HP printers have a small screen or panel on the front that shows cartridge status without needing a computer. Look for a button labeled "Info," "Status," or a small icon that looks like a drop or cartridge — pressing it will display how much ink remains in each color.
If your printer has no screen, look for a small light on the cartridge door. Some HP models use colored lights: green means the cartridge is fine, amber or yellow means it is running low, and red means it is nearly empty. Open the cartridge access door on the front or side of the printer to see the lights clearly.
For very basic HP printers without screens or lights, you may need to remove each cartridge and look at the fill level through the plastic window on the side. This is the least convenient method, but it works if nothing else is available on your machine.
Key Takeaways
- Most HP printers show ink levels on a front panel or screen — look for an Info or Status button to display the current level of each cartridge.
- If your printer has no screen, check for colored indicator lights on the cartridge door that show whether ink is low or running out.
- The HP Smart app on your phone or computer can show ink levels remotely and alert you before cartridges run dry.
- Ink level warnings on the printer screen or in software are estimates, not exact measurements — a cartridge may still print after the warning appears.
Checking ink levels through the HP Smart app
If your HP printer is connected to Wi-Fi, the HP Smart app is the easiest way to check ink from anywhere. read the app on your phone or computer, sign in with your HP account, and your printer will appear in the list of devices. Tap or click on your printer, and the ink levels for all cartridges will display as percentages or bars.
The app also sends notifications when ink is running low, so you know to order a replacement before you run out mid-print job. You can even reorder cartridges directly from the app if your printer model supports it, though you are not required to use HP's cartridges — third-party options work in most machines.
If you do not have an HP account yet, you will need to create one to use the Smart app. This is free and takes about two minutes. Once set up, the app works on any device you log into, so you can check your printer's status from your phone while at work or away from home.
Using the printer's web interface
Every networked HP printer has a built-in web page you can open in any browser. Find your printer's IP address by pressing the Info or Status button on the printer panel — it will display a number like 192.168.1.100. Type that number into your browser's address bar (for example, http://192.168.1.100) and press Enter.
Once the page loads, look for a section called "Supplies," "Cartridges," "Ink Status," or "Device Information." This page shows the exact percentage remaining in each cartridge and sometimes predicts how many pages you can still print before running out. The web interface also lets you disable low-ink warnings if you want to keep printing even after the cartridge is flagged as low.
If you cannot find your printer's IP address on the panel, print a network configuration page. Open the printer's menu, navigate to Settings or Network, and select "Print Network Configuration" or "Print Settings." This page lists the IP address clearly.
Understanding ink level warnings and estimates
HP printers estimate ink levels by tracking how much ink the printer thinks it has used since the cartridge was installed. This is not a direct measurement — it is a calculation based on the number of pages printed and the coverage of those pages. Because of this, the estimate can be off by 5 to 15 percent in either direction.
When your printer shows a cartridge is at 5 percent or displays a "low ink" warning, the cartridge usually still has enough ink to print 50 to 100 more pages, depending on what you are printing. Text pages use less ink than photos or graphics, so a low-ink warning does not mean you have to stop printing when ready. However, once a cartridge reaches 0 percent, the printer will refuse to print until you replace it.
If you see a warning but do not want to replace the cartridge yet, you can usually dismiss the warning on the printer panel or in the HP Smart app. The printer will continue to work and will remind you again the next time you print.
What to do when a cartridge shows empty
When a cartridge reaches 0 percent or displays "empty," the printer will stop printing and show an error message. At this point, you must replace the cartridge — there is no way to continue printing without doing so. Open the cartridge access door, press down on the empty cartridge to release it, and slide it out.
Before installing a new cartridge, check the model number on your printer or in the HP Smart app to make sure you buy the right one. HP cartridges are labeled with numbers like 63, 64, 65, or 302 — using the wrong number will not fit or will not work properly. You can buy cartridges from any retailer, not just HP, and third-party cartridges work in most machines.
Once you have the new cartridge, remove the protective tape or plastic from the bottom, slide it into the empty slot, and push down until it clicks. Close the cartridge door, and the printer will recognize the new cartridge automatically. The ink level in the HP Smart app and on the printer panel will reset to 100 percent.
Checking ink on older HP printers without Wi-Fi
If your HP printer is older or does not have Wi-Fi, you can still check ink levels through a USB connection. Install the HP printer software on your computer (read it from hp.com if you do not have it), connect the printer with a USB cable, and open the printer software. Look for a "Supplies" or "Device Status" section that shows cartridge levels.
Some older printers display ink status only through this software and not on the printer itself. If the software does not show ink levels, your printer may not have this feature — in that case, the only way to check is to open the cartridge door and look at the fill level visually or remove each cartridge to see the window on the side.
If you no longer have the original software disc, you can read the drivers and software from hp.com by entering your printer model number. The read is free and usually takes less than five minutes to install.
Frequently Asked Questions
Why does my HP printer say the cartridge is empty when it still prints?
HP printers estimate ink levels based on page count, not actual measurement. When a cartridge reaches 0 percent, the printer assumes it is empty even though a small amount of ink may remain. You can usually dismiss the warning and keep printing for another 50 to 100 pages, but eventually the cartridge will truly run dry and the printer will stop.
Can I check ink levels on my HP printer without the Smart app?
Yes. Press the Info or Status button on the printer panel to see levels on the screen, check the colored lights on the cartridge door, or open the web interface by typing your printer's IP address into a browser. The Smart app is convenient but not required.
What if my printer is not showing ink levels anywhere?
Very old HP printers or basic models may not have an ink level display feature. In that case, open the cartridge access door and look at the plastic window on the side of each cartridge to see how full it is. You can also remove a cartridge and hold it up to the light to judge the fill level.
Do I have to use HP cartridges, or can I use third-party ink?
You can use third-party cartridges in most HP printers. They work the same way and cost less, though HP will not may provide their performance. Some printers may show a warning that you are using non-HP cartridges, but this does not prevent printing. Buy from a reputable seller to avoid low-quality ink that may damage your printer.
Why is my ink level stuck at the same percentage for weeks?
If you print very little, the ink level estimate may not change noticeably because the printer tracks usage by page count. If you print a lot of graphics or photos, the level will drop faster than if you print mostly text. The estimate updates each time you print, so heavy use will show a faster decline.
