If your printer is not printing, the cause is almost always one of a handful of common issues: a paper jam, an empty or clogged ink cartridge, a driver problem, or a connection failure. This guide walks you through each likely cause in order, with exact steps to get your printer working again quickly.
Quick Checks Before You Dive In
Before opening any software or removing cables, run these 30-second checks. They resolve a surprising number of “not printing” cases:
- Power: Is the printer actually on? Many models have a power light that stays lit even when the printer is in a sleep state. Press the power button once to wake it.
- Paper: Is paper loaded and pushed back until it clicks? Is it curled, damp, or over the fill line? Remove and re-stack it.
- Error lights: Blinking or solid orange/red lights usually indicate a jam, empty ink, or an open cover. Look at the printer’s front panel for a message or icon.
- Print queue: On your computer, open the print queue (see below) and check if your document is stuck with a “Paused” or “Error” status. If so, cancel all jobs and try again.
Step 1: Check the Print Queue
The most common software reason a printer “does nothing” is a stuck print job. A previous job with an error (like a paper jam) can block everything behind it.
- Open the print queue: On Windows, go to Settings > Bluetooth & devices > Printers & scanners, click your printer, then Open print queue. On Mac, go to System Settings > Printers & Scanners, click your printer, then Open Print Queue.
- Look for any document with a status like “Error”, “Paused”, or “Deleting”.
- Select that job and click Cancel (or the X icon). If it won’t cancel, restart the print spooler service (Windows) or the printer itself.
- Try printing a test page from the printer’s properties window. If that works, your printer hardware is fine and the issue was the stuck job.
Step 2: Verify the Connection
Printers connect via USB cable, Wi-Fi, or Ethernet. Each has its own failure modes.
- USB: Try a different USB port on your computer (preferably a port directly on the motherboard, not a hub). Check that the cable isn’t damaged. Reconnect it firmly.
- Wi-Fi: Printers often drop off the network after a router change or a power outage. Check the printer’s network status page (usually printed by holding a button, or found in its menu). Ensure your computer and printer are on the same network (e.g., both on the 2.4 GHz band, not one on 5 GHz and the other on 2.4 GHz).
- Ethernet: Check the link lights on the printer’s network port. If they’re off, the cable or router port is the problem. Try a different cable or port.
If the connection looks fine but printing still fails, run the printer’s built-in network test (usually under “Network” or “Settings” in the printer menu). If the test shows an IP address of 0.0.0.0, the printer hasn’t obtained an address from your router.
Step 3: Clear Paper Jams Properly
Paper jams are the #1 hardware cause of “not printing”. Even a tiny scrap of torn paper can stop the printer.
- Turn the printer off and unplug it. Wait 30 seconds.
- Open the front, rear, and any access panels. Look for jammed paper, especially in the rollers near the back.
- Gently pull the paper out in the direction it was feeding (usually upward or forward). Pulling against the feed direction can tear it.
- If paper tears, use tweezers to remove the pieces. Check the rollers for any stuck bits.
- Close all panels, plug the printer back in, and turn it on. Most printers automatically reset the jam error.
If you can’t see any paper but the printer still reports a jam, the sensor may be blocked by dust or a torn piece. Use a flashlight to inspect the paper path.
Step 4: Check Ink and Toner Levels
Many printers refuse to print (or print blank pages) when a cartridge is empty, even if you only need black and the color is empty. Some models also stop if a cartridge is very low to protect the printhead.
- Open the printer’s status software on your computer (often called “HP Smart”, “Epson Status Monitor”, or “Canon IJ Status Monitor”). Look at the ink/toner levels.
- If a cartridge shows empty or very low, replace it. If it shows full but you’re getting blank pages, the printhead may be clogged.
- For inkjet printers, run the built-in Nozzle Check and Printhead Cleaning utility (found in the printer software under “Maintenance” or “Tools”). This pushes ink through the nozzles. You may need to run it 2-3 times, but don’t overdo it—excessive cleaning wastes ink.
- For laser printers, if you see faint or streaked output, the toner cartridge may be low. Gently rock the cartridge side-to-side to redistribute toner, then reinstall.
Step 5: Update or Reinstall the Driver
A corrupt or outdated driver is a common cause after a Windows or macOS update. The printer may appear “ready” but jobs fail instantly.
- Go to your printer manufacturer’s support website and download the latest driver for your exact model and operating system version.
- Uninstall the current driver first: On Windows, go to Settings > Apps, find the printer software, and uninstall it. On Mac, delete the printer from Printers & Scanners.
- Restart your computer, then install the new driver.
- Add the printer again (Windows: Settings > Bluetooth & devices > Printers & scanners > Add device; Mac: Printers & Scanners > Add).
If the manufacturer’s driver still fails, try the built-in Microsoft or Apple driver as a fallback—it may be more stable for basic printing.
Step 6: Set the Default Printer and Check Settings
Sometimes the printer is fine, but your computer is sending the job to a different device (like a fax or a PDF printer).
- On Windows, open Settings > Bluetooth & devices > Printers & scanners. Check the box that says “Let Windows manage my default printer”—or manually click your printer and select Set as default.
- On Mac, go to Printers & Scanners, right-click (or Control-click) your printer and choose Set as default.
- In the print dialog, double-check the selected printer name, paper size, and orientation. A mismatch (e.g., the printer has A4 but the document is Letter) can cause a silent failure or a paper jam.
Frequently Asked Questions
Why does my printer say “offline” when it’s on?
This usually means the computer can’t communicate with the printer. Check the connection (USB or Wi-Fi), then in the print queue click “Use Printer Offline” to uncheck it. On Windows, also try restarting the Print Spooler service (search “services.msc”, find “Print Spooler”, right-click and Restart).
Why is my printer printing blank pages?
Blank pages from an inkjet usually mean clogged printheads or empty ink. Run a nozzle check and cleaning cycle. For a laser printer, blank pages often indicate a toner cartridge issue—try reseating it or replacing it. Also check the document itself: if it’s a PDF with only images, the printer might be out of memory; try printing at a lower quality.
Why does my printer say “paper jam” when there’s no paper?
A sensor is likely blocked by a torn piece of paper, dust, or a foreign object. Open all access panels and inspect the paper path with a flashlight. Remove any debris carefully. If the error persists, the sensor may be faulty and need professional service.
Why won’t my printer print after a Windows update?
Windows updates can replace or corrupt printer drivers. Reinstall the latest driver from the manufacturer’s website, or use the Windows built-in driver (“Generic / Text Only” or the model’s name). Also check that the printer is not set to “Pause printing” in the queue.
Why does my printer print slowly?
Slow printing is often due to high-quality settings, a busy network, or a large file. Try changing the print quality to “Draft” or “Standard”. For wireless printers, move the printer closer to the router or use a USB cable. Also check if the printer’s firmware needs an update.
Why does my printer print with streaks or lines?
For inkjets, streaks usually mean clogged nozzles or low ink. Run a nozzle check and cleaning cycle. For laser printers, streaks are often caused by a dirty drum or a low toner cartridge. Try cleaning the drum with a soft, dry cloth (if accessible) or replacing the toner.
