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.

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.
In the search box on the taskbar, type control panel and then select Control Panel. Under Hardware and Sound, select View devices and printers. Select and hold (or right-click) the printer you want to share, select Printer properties, and then choose the Sharing tab. On the Sharing tab, select Share this printer.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

Common factors include driver problems, software issues, hardware failures and overuse.
Make sure that both ends of the USB cable are correctly inserted into the computer and the printer. Try disconnecting and reconnecting the USB cable at both ends. Disconnect the printer and the computer and reconnect them. Try another USB port if available.
Start your mobile application and tap the Settings icon. (Mobile Cable Label Tool users must also tap [Printer Settings] – [Printer].) Select the printer listed under [Wi-Fi Printer]. You can now print from your device wirelessly.
Click on Device Manager from the context menu. In Device Manager, click on View and select Show hidden devices. Next, expand the Printers section to view your printer.
Ghost printers are printers that continue to appear in Windows although they have not been used or installed on your system in a long time, which may have been years.
Viewing Printer Settings

Need help for cleaning epson r300, have a kit
ANSWER : Don’t worry about the paper towel. Keep the heads as far to the right as you can and the fluid will just go into the waste sponge underneath. There’s nothing you can damage with the fluid. I wouldn’t worry about the pad that got torn. Just insert the syringe in the nozzle and gently push the fluid down into the heads. This site sold tens of thousands of those kits and I guess the instructions were pretty good because there was never a single complaint.

Need help
ANSWER : I usually look for screws that might be holding it. If it doesn’t come off after removing the screws, sometimes you have to slide it to remove it. If that doesn’t work, then you get out the small, flat bladed pocket screwdriver. Use it to gently pry around the edges of the panel. Have you tried grabbing the paper clip with some needle nosed pliers? Either that or a small magnet to pull it out. Another possibility would be to hook the clip and pull it out that way.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.

Toner cartridge full, printer displays: "empty needs replacing"
ANSWER : I once went to a customer who had a similar issue. They had installed new cartridges and judging from the box, they looked OEM. Strange thing was they felt empty when lifted and they were missing the chip on the outside that tells the printer it is installed and keeps track of how many copies were printed with that cartridge. The printer has no other way of knowing if the cartridge is full or empty.
