How to Identify and Fix Common Problems ?

When HP Smart displays the “Printer status unknown” error, the app can`t communicate with your printer. Issues with your printer connection, firmware, or driver are often responsible for this error message.
Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

No set standard makes a printer-specific to photos. You can, in theory, use almost any home printer to create black-and-white or color prints. Most printer software products include custom settings that will change the resolution of your print job to make them near perfect for photos.
There is no ribbon, ink or toner involved with direct thermal printing. Instead, the printhead applies pressure and heat directly onto the surface of heat-sensitive thermal paper. The thermal paper reacts to the heat of the printhead, blackening when heated and producing an image or text.
Changing the status of the printer:

In the Devices and Printers window right-click or tap and hold on your printer and select See what`s printing. Click or tap the Printer tab, then untick Use Printer Offline from the menu.

Open the start menu and select Control Panel > Administrative Tools > and choose the Services icon. Locate the Print Spooler service and right-click. Then select the option to “Stop” the service.
Usually a quick paper setting adjustment will clear up a ghosting issue right away. Run a cleaning – Most printers have a cleaning function built into the machine. Run this a couple of times to attempt to clear up the printing issue. Inspect the drum – Sometimes excess toner powder can stick to the drum.
The best photo printer overall: Canon Pixma Pro 200

The print quality is comparable to Canon`s more expensive Pro 300 model and, in our test, a bit better than the Epson P700. This model uses an eight-color, dye-based ink system.

Digital printing is rapidly becoming the industry standard for creating different photo prints. It is more expensive than other printing methods (i.e., offset lithography). However, technical steps to make the images are much simpler, and the turnaround time is faster than many other printing methods.
Certain printers can print with an empty cartridge, while others require that all cartridges have some ink. Identify your cartridge type for details.
An inkless printer does exactly what its name promises – it prints without using any ink. The printer uses heat-based technology to darken parts of the paper. The technology uses heliochromic chemicals and UV light.
Reasons why your HP printer has ink but won`t print

This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.

There are numerous possible causes for a printer that`s randomly producing blanks. The most common ones are empty ink cartridges, improper cartridge installation, and congested nozzles. Driver and software issues can sometimes cause this problem as well.
Viewing Printer Settings

From the Devices and Printers screen, right-click on a printer and choose “Printer properties” to bring up a dialog box displaying the printer name, sharing settings and port information.

In Settings, go to Network & Internet, find Network and Sharing Center, go to Change advanced sharing settings and uncheck Turn on automatic setup of network connected devices. Alternatively, if you have Network Discovery disabled the same result happens. This applies to all user profiles on the workstation.
Open Settings -> Devices -> Printers and Scanners (or run a quick access URI command: ms-settings:printers ); Select a printer you want to remove and click Remove Device; Confirm the printer removal.
Ghost images, like those created by cataracts, usually are seen by only one eye. Ghost images can occur after corneal surgery, such as LASIK, PRK or a corneal transplant. Most of these problems disappear when the problem is resolved, like after cataract surgery or when the refractive surgery heals.
If the paper is too thick, glossy or not designed for laser printing, ghosting will most likely occur. Dust and debris inside the printer can also cause ghosting as too much dirt can interfere with the drum units, transfer units and fuser units.
The Quality of The Print

The first thing that will impact the price is the quality of a print. Not all prints are created equal, and if a photographer prints for you they will probably have access to professional printers and will be offering you a higher quality of print than you would find on the high street.

Conclusion. In the end we can say that both home and professional photo printers use the same inkjet-based quality, but the professional ones differ in that they have more ink cartridges and can print at higher resolutions. But if you are not a professional, then go for inkjet printers.
At the basic level, printers work by converting digital images and text into physical copies. They do this using a driver or specialized software that has been designed to convert the file into a language that the printer can understand. The image or text is then recreated on the page using a series of minuscule dots.
For most artwork, 300 dpi is preferred. Most printers produce excellent output from images set at 300 ppi. You can use 150 dpi for large prints because the difference in print quality is not very noticeable on large pieces when you look at the prints from a distance.
Use High-Quality Paper

Perhaps the best thing you can do to make high-quality digital photo prints at home is to use specialty photo paper. Either glossy or matte photo paper works much better than standard printing paper. But because specialty photo paper can be expensive, be sure to only print your best photos on it.

So, when it comes to printing, know that PNG files are an excellent option for delivering good quality printouts using office or home printers. This is because these files contain high-resolution images and better color depth. Images from JPEG files become blurry in printouts.

Print file sent but no printing occurs
ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.

Paper feeds straight through without printing on an Epson R2400
ANSWER : I was able to get it to print the internal test page by holding down the sheet paper feed button while turning the machine on — then continuing to hold the sheet paper feed button. It took several attempts, feeding a page straight through, but eventually it caught the sheet and printed. So it may be a timing issue as others have mentioned. It could still mean that the feed rollers are worn out. The back side of the large D-shaped feed roller has visible abrasion on it. The abrasion is difficult to see as the roller does not stay with the flat side exposed.
