HP printer guide
Print the full-path browser sheet, then print HP’s own Print Quality Report or Printer Status Report from the printer. If both show the same defect the printer needs attention; if only the browser sheet does, the computer, driver or queue does. That difference decides whether cleaning, aligning or a driver reset is your next move.

8 pt — Fine text should remain crisp, evenly filled and easy to read without halos, feathering or broken strokes.
6 pt — If this line is legible and consistent, your printer is resolving small type well.Print it right
A scaled or economy-mode print can look like a printer fault. Start with a controlled print before changing ink, toner, or hardware.
Use Normal quality, 100% scale and the paper size loaded. In the HP driver turn off Print in Grayscale and any EconoMode or Draft setting. This tests the app, the HP driver, the USB or Wi-Fi link and the printer as one chain.
On a touchscreen: Setup or Tools → Reports (or Printer Reports) → Print Quality Report or Printer Status Report. In HP Smart, open the printer’s settings and look for Printer Reports or Tools. On button-only DeskJets, holding the Cancel or Resume button for a few seconds prints a status report; the manual names the button. On LaserJets: Reports → Print Quality Page or Configuration Page.
Matching defects on both sheets point at supplies, nozzles, alignment or hardware. A clean HP report with a faulty browser sheet points at software: a driver preset, the queue, the app or the connection. Only then choose between Clean Printhead, Align Printhead, a driver reset or a supply change.
Read the result
Inkjet: nozzles in that color are clogged or the cartridge is nearly empty. LaserJet: toner transfer is uneven or the cartridge is low and toner is not reaching one side of the drum.
Inkjet: Tools → Clean Printhead (or Clean Cartridges) once, then reprint the Print Quality Report. Laser: check toner level, redistribute toner only if the manual permits, then reprint.
The print engine and supplies are fine. The fault is the driver, a preset, the queue, the connection or the app.
Open Printing preferences and Restore defaults, clear the queue, confirm the queue uses the exact model driver rather than a generic class driver, and print from another app or browser.
EconoMode or Draft, low black ink or toner, a blocked black channel, or the wrong paper type. Instant Ink cartridges stop working entirely if the subscription lapses, so a sudden refusal to print, rather than pale output, points there.
Turn off Draft and EconoMode, check the black supply, and compare against the black-only test.
Inkjet printhead alignment has drifted, commonly after a cartridge change or a jam. On a laser, doubled edges usually mean color misregistration or a worn transfer component.
Inkjet: Tools → Align Printhead (or Align Cartridges) and reprint this sheet. Laser: run Calibration or Color Calibration from the printer’s menu.
Protective tape or a vent seal is still on, the cartridge is not clicked home, or the printer’s firmware does not accept the cartridge chip. HP’s Dynamic Security can block cartridges with non-HP chips after a firmware update.
Remove the tape, reseat the cartridge, and read the display for a supply message. If it is a chip rejection, only an HP or HP-accepted cartridge will clear it.
Air in the tubes or a tank below its minimum line. Smart Tank printers feed the printhead from bottles through tubes, and an empty tank lets air in.
Fill the tanks above the minimum line, then run Clean Printhead once from Tools. Run a second level of cleaning only if the report still shows gaps.
A rotating component is damaged or dirty. HP’s Print Quality Troubleshooting Page and the model’s repetitive-defect ruler map the spacing to the imaging drum, developer roller, transfer roller or fuser.
Measure the spacing with a ruler, match it in the HP service manual, and replace or clean that part rather than the toner.
HP inkjets print two useful pages from the printer itself. The Printer Status Report lists the model, firmware, connection and estimated ink levels, with a small set of color bars at the bottom; it is the quickest way to confirm supplies and network state. The Print Quality Report (on some models the Print Quality Diagnostic Page) is the one that matters for streaks and color: it prints numbered color blocks and line patterns designed to expose clogged nozzles, missing colors and misalignment.
Both pages come straight from the printer’s firmware without a computer, which is exactly what makes them useful. If a Print Quality Report is clean, the printhead, ink and paper path are working and any bad document is coming from the computer side.
HP’s Clean Printhead routine runs in stages, and each stage pushes ink through every nozzle, not just the blocked ones. A single first-level cleaning is cheap; running every level several times in a row can consume a noticeable share of a small cartridge and still not clear a channel that is simply empty. Print the Print Quality Report first. If it shows gaps, run one cleaning, reprint the report, and stop as soon as the gaps close.
If two rounds do not help, look for a reason cleaning cannot fix: an empty cartridge whose gauge still shows ink, a vent seal left on, a cartridge not seated, or on integrated-head cartridges (most DeskJet and ENVY models) a head that has simply worn out and needs a new cartridge.
Alignment corrects where each drop lands relative to the others, so it fixes doubled lines, jagged verticals, color fringes on black text and stepped diagonals. It does nothing for pale colors, missing blocks or white streaks, which are supply and nozzle problems. Run Align Printhead or Align Cartridges from the Tools menu, from HP Smart, or from the printer’s touchscreen after installing a new cartridge or printhead, after a jam, and after moving the printer. Then reprint this sheet and compare the grid and the 6 pt line.
LaserJet printers use toner, a drum and a fuser, so they need laser rules. A uniformly pale page is usually EconoMode, a low cartridge or the wrong paper type. Toner that smears under a finger has not fused: the paper is too heavy or damp for the setting, or the fuser is failing. Gray background or specks point to a worn drum or a contaminated cartridge. A mark that repeats at a fixed interval follows a roller; HP’s Print Quality Troubleshooting Page and the model’s repetitive-defect ruler map that interval to the drum, developer, transfer roller or fuser.
On color LaserJets, doubled or fringed edges mean color misregistration, which the printer corrects itself through Calibration in the menu. Run it before assuming a hardware fault.
FAQ
Print the browser sheet above at 100%, or print HP’s own page from the printer. On touchscreen models go to Setup or Tools → Reports → Print Quality Report or Printer Status Report. In HP Smart, open the printer’s settings and choose Printer Reports. On button-only DeskJets, holding the Cancel or Resume button for a few seconds prints a status report; the manual names the button. LaserJets have a Reports menu with a Print Quality Page or Configuration Page.
A diagnostic page the printer generates from its own firmware, with numbered color blocks and line patterns. Streaks or gaps in a block mean clogged nozzles or low ink in that color; broken lines mean misalignment. Because no computer is involved, a clean report proves the printhead, ink and paper path are working.
The print engine works, so the problem is between the computer and the printer. Check that the correct HP queue is selected and not paused, clear stuck jobs, restart the printer and the computer, and confirm the connection; a printer that moved to a different Wi-Fi network after a router change is a common cause. Then print a simple document from another app. If that works, the original app or its print preset was the issue.
Only when the Print Quality Report shows gaps, and then once at a time. Each level pushes ink through every nozzle. Reprint the report after each cleaning and stop when it is clean. If two rounds do not help, the cartridge is probably empty, sealed or worn out, and cleaning will not fix that.
Yes. The color or gray blocks, ramp, grid and type patterns work on LaserJet, LaserJet Pro and Neverstop models. Read them with laser rules: no nozzle cleaning. Pale output means EconoMode or toner, repeating marks mean a drum or roller, smears mean fusing or paper. Use the printer’s Print Quality Page and Calibration menu.
Usually the protective tape or vent seal is still on, or the cartridge is not clicked fully home. Remove it, check for tape on the contacts and nozzles, reseat it firmly and close the door. If the message persists with a non-HP cartridge, the printer’s Dynamic Security firmware may be blocking the chip; only an HP or HP-accepted cartridge will clear that.
Not the printing itself, but an Instant Ink cartridge stops working if the subscription ends, so a printer that suddenly refuses to print rather than printing badly may have a subscription issue, not a hardware one. Check the printer’s display and your HP account before troubleshooting print quality.
