Print quality issues usually indicate a physical problem with the printer or the cartridges being used. Sometimes the nozzles on inkjet printer heads can become blocked causing horizontal streaks on prints and poor or inaccurate color reproduction. These steps can help assist with resolving print quality issues.

Every printer is different and the following steps are generalized. Your printer may require that the print head be physically removed, while others cannot be physically removed at all. For explicit instructions on how to properly clean the print head on your printer, consult your device's documentation.

  1. Load plain white paper into your printer's paper tray.
  2. Press the Setup button.

  5. Examine the test sheet for print quality. Consider repeating the cleaning if there is improvement. If the print head is badly clogged, you may need to clean the print head several times in order to restore normal print quality.
  6. Recycle or discard the test sheet.
  7. When the cleaning process completes, press any button on the control panel to return to the Tools menu.
  1. Open the cartridge access door.

While your printer has the ability to print almost anything on your screen, lots of things that you may want to print are not always formatted to come out of your printer in such a way that makes sense. If you're experiencing issues with being able to properly print something, you may be running into one of the following issues.

The desire to print content from web pages is common amongst computer users. However, much of what is posted online is not constructed or formatted for standard 8 1/2 x 11 printer paper. This results in print jobs from web pages looking very much like the image below. All items on the screen will be printed, including advertisements, menus, etc.
Screenshot of a common print preview screen depicting what will be printed.
To avoid this, always look for a "printer friendly" version of the content you would like to print. Some websites will offer a Print button someplace on them, which will open a version of said content that is indeed formatted with printing in-mind.

Similar to printing webpages, you may experience issues when attempting to print certain Microsoft Office documents - namely Excel spreadsheets. Due to spreadsheets not being confined to the size of traditional 8 1/2 x 11 printer paper, many columns and rows may extend far past these limitations and may simply be left out when printed.

Depending on your individual printing needs, Excel does offer options that may help with getting what you'd like to see printed out properly.

Inconsistencies when printing photos can be very common. You may experience issues like the ones depicted in the images below. Some things to always be aware of when printing photos:

  • If you are using a non-standard sized paper to print photos on, the size of the paper will need to be specified on the print window before printing. Otherwise, your printer will assume that standard letter-sized paper is being used.

  • The physical size or resolution of the photo can make a big difference. If a small photo is stretched to fit a larger sheet of paper, the image quality will be poor. Conversely, if the image is larger than the page it is being printed on and is not sized down to fit the paper, much of the image will be cut off.

Many users are today reporting that their HP printer software has suddenly stopped working, with worrying messages implying that their software is malicious and “will damage your computer”. Given the recent problems with MRT version 1.68, it’s easy to ascribe this to the same update, although this message clearly isn’t coming from MRT. Could it be that the XProtect update was also broken?

Thanks to the work of Thomas Reed at Malwarebytes, I can answer that this is completely unassociated with XProtect or MRT. You’re seeing that message because macOS is checking the signature on your HP printer software, and being told that its signing certificate has been revoked. What’s strange, though, is that this doesn’t appear to affect High Sierra and older versions of macOS.

If you ever see an error alert reporting this type of problem, first check the signature on the software that it refers to. If you’re not adept at doing that in Terminal, open my free ArchiChect, drag and drop the item onto it to see its report.

revocation

At the top of the text you’ll see a line starting with a No Entry sign: this indicates a serious signature error, in this case indicating the code signing certificate has been revoked. macOS therefore won’t allow you to run this software. You can’t argue, and should next wonder why this might have happened. Maybe this certificate is being abused on other software which is behaving maliciously? If you’re uncertain what’s going on, contact Apple Support, and the vendor of the software, who may be able to provide further information.

So why don’t earlier versions of macOS reflect the same revocation?

This may well be because they’re working with different databases. Until a year ago, we thought that the certificate revocation database was stored locally, in what we termed the Gatekeeper security database. As I’ve recently reported, that hasn’t been updated for over a year now, and Catalina doesn’t seem to even open it any more. So different versions of macOS may well behave differently when Apple revokes certificates.

Thomas Reed has raised this revocation with Apple. As soon as we know anything more, I’ll update this article. If you’re interested in Mac security, you might like to follow Thomas on Twitter, @thomasareed.

In the meantime, all you can do is make alternative arrangements to support any HP printers affected, I’m afraid.

Update: The previously revoked signature has now been unrevoked, as of the night of 24-25 October. Thanks to Mr Macintosh for spotting this. Your old HP printer software should now work correctly again.
(0750 UTC 25 October 2020)

According to an unnamed spokesperson at HP quoted by The Register, this revocation wasn’t an error by Apple, but HP had instructed Apple to revoke the certificate. Note that the first part of that article referring to XProtect isn’t accurate: this had nothing to do with XProtect at all.
(0805 UTC 25 October)

Further Update:

Despite the apparent un-revocation of the certificate, many HP users are still reporting problems which appear to be related to signature errors. I’ve checked my HP software here, from 2017, and although its apps and some of its code now passes checks, at least on of its frameworks (HPMonitoringDevice.framework) still returns an error 3, reporting “source=Unnotarized Developer ID”, and might fail to load when required in Catalina.

If you still have problems, please contact HP Support. There seems little or nothing that we can do about this, and its resolution rests in the hands of the developer of the software. If you do attempt any surgery yourself, for example by removing the certificates, please ensure that you have good backups and some means to restore them, or you could make your problems worse.

(2240 UTC 26 October)

Postscript (27 October 2020):

HP has now published a support article explaining what affected users should do to remedy this problem. I suspect this only works with its software for relatively recent printer models. Thanks to @macinteractive for drawing my attention to this.

Top 10 HP printing problems and how to fix them

by Scott Lowe MCSE in Printers on September 9, 2003, 12:00 AM PST

While Hewlett-Packard printers are known for their reliability, they still need a helping hand from time to time. From the ubiquitous paper jam to the vexing 50.4 error, this article offers a top 10 list you can use to troubleshoot any HP printer.


While they're generally very reliable, even in the most demanding of environments, HP printers are still problematic from time to time. And we all know printers fail at the most inopportune moments. For an IT support professional, it's critical to know how to fix the most common problems associated with these printers. I've identified 10 problems you can expect to run into most often when dealing with an HP printer, and I've included suggestions on fixing them.

1. Paper jams
Among the most common problems with any make of printer are paper jams. A printer will jam for any number of reasons: It’s dirty, the wrong paper type is being used, or the rollers on the printer that feed the paper through its pathway are worn down. While cleaning the printer periodically and using the correct paper type are easy fixes, roller replacement can be a difficult job depending on the model of HP printer. For some HP printers, the rollers are easily accessible, but you'll need to completely tear down other models to remove the rollers. Regardless of the cause, when removing a paper jam, always pull the paper in the direction of the paper path, because pulling it backwards can severely damage the printer.

Certain HP printers are more susceptible to paper jams than others. In my experience, any printer that holds the paper vertically and then pulls it down through the printer invariably ends up having paper jam problems. These models aren't designed for heavy use, but many organizations make use of them on individual systems and should be aware of this flaw. In addition, some people have trouble with the newer HP 4000 series printers' paper pickup rollers—which is odd, because the older 4000 and 5000 series HP printers are considered rock solid and don't seem to have any trouble with their pickup rollers.

2. Some or all of the printing on the page is faded
A faded print image is normally the result of one of three conditions: The printer is getting low on toner, the print density is set too low, or Economode printing is turned on. For the last two settings, a printer self-test (typically a separate button on the printer) will show what the current settings are. If Economode is on, and users are complaining about how light the print is, turn it off and/or set the print density higher. If the toner is low, simply removing the cartridge and shaking it to redistribute the toner more evenly can temporarily resolve the problem until you can replace the cartridge.

3. Ghosting
Ghosting is a condition where the image prints properly, but a much lighter copy of the image also prints elsewhere. This can be due to a problem with the power outlet that is supplying power to the printer. Check the power outlet by plugging in a different printer to see if the same results occur. Ghosting can also be caused when consumable printer parts (such as the drum or imaging kit) are near the end of their life. All of the consumable parts in a printer are rated for a certain number of pages. Once a printer gets near that magic number, you'll need to replace those parts to eliminate ghosting.

4. Toner smears or does not stay on the paper
If words and images come off the paper when a hand is run across them, there are a few possible problems. First, the fuser assembly may be damaged or at the end of its life. The solution is to replace the fuser assembly. Repairing a fuser assembly is generally not recommended because the fuser is considered a consumable printer part and not worth the time or effort to fix. Second, the toner cartridge may be defective and letting too much toner out at one time. In a black-and-white laser printer, the solution is to replace the toner cartridge. In a color laser printer, only replace the cartridge that is exhibiting the problem. Third, some toner may have spilled in the printer. If so, you'll need to clean it out.

5. Printer is displaying a 50.4 error message
A 50.4 error message on some of the newer HP LaserJet printers indicates a problem with the power supply. If the printer is connected to a UPS, disconnect it, or disconnect it from a power strip and plug it directly into a wall outlet. A laser printer should never be plugged into a UPS, because the UPS can be damaged by the surges of power required by a printer to keep the fuser assembly warm. If that doesn’t work, make sure that all of the components in the printer are seated properly.

6. Can't find a driver for a particular operating system
As new operating systems are released, new drivers will need to be loaded for your existing printers. Not all printers have a driver for every OS. In these cases, it’s best to consult the printer manual and find out what printers the drivers will emulate. While not all of the functionality of the printer will be available under this emulation, at least basic printing will work. For example, most HP printers will print with the HP LaserJet II driver installed, although specific options, such as duplexing, will not work.

7. Printer is not printing from the expected paper tray
Look in two places to correct this particular error. First, look on the printing PC, and second, on the printer. If the application is set to print to the wrong paper tray, correct it within the application by clicking on Printer Properties and finding the Tray Selection source. On the printer, make sure that the paper sizes in the control panel match what is actually in the paper trays.

8. Printer picks up all the paper from the manual feed tray rather than one sheet
The pad that is responsible for separating the paper has likely worn out and needs to be replaced. You can order and install a new pad without sending the printer out for repair. It is also possible that the paper is wet due to humidity. Make sure the paper is properly stored and that it is “fanned” before putting it into the printer.

9. Printer is displaying a 79 error
A 79 error can be the result of a problem with the network print server that services the printer. When troubleshooting a 79 error, first open the Printer folder from the Start menu on the Print server to make sure there are no jobs pending. A 79 error can also indicate a failure of a printer add-on component, such as an MIO card or a RAM module. All add-ons should be removed and then added back to the printer one by one to determine which module may be at fault.

10. Trouble printing onto envelopes
Envelopes can cause many problems for laser printers. Choose envelopes that are close to 20-lb paper in weight and thickness. Also, make sure that the adhesive on the envelope is capable of withstanding the heat that the fuser puts out to keep the printing on the page. If you don’t, the envelopes will come out of the printer already sealed. If envelopes are coming out of the printer wrinkled, they may be too stiff for the paper path. Open the rear of the printer and let them exit at that location instead.

HP printers are considered to be among the most reliable in the industry. But just as any other piece of IT equipment, they're vulnerable to failure. And it seems the newer printers can’t withstand the same amount of abuse that the older models could. So if you work on newer-model HP printers in a paper-intensive environment, expect more troubleshooting calls involving the problems I've described. But no matter what the age of your HP printer, this guide to common printing problems will help you diagnose and fix the problem quickly.
