HP has determined that 99% of all lines and streaks on copies made by feeding the original documents through the ADF are caused by debris on the ADF glass. Debris can include dust, paper or toner dust, residue from sticky note adhesive, correction fluid or tape, ink, fingerprints, and more.
Vertical lines in prints are an early warning sign of a low ink cartridge, which may show up before the printer`s low ink alerts start. You can fix the problem by replacing the low cartridge. Gently shaking the drained cartridge a bit may help to get another few prints out of it without vertical lines.
The streaks or lines might be caused due to low ink levels in one or both ink cartridges. Check the ink levels using the HP Toolbox to determine if the ink cartridges are low on ink and need to be replaced. note: Ink level warnings and indicators provide estimates for planning purposes only.
Change mode in printer settings

Open the Control Panel and then the Devices and Printers option. Find your printer in the Devices and Printers window and right-click the icon with your mouse. In the menu that appears, select Printing Preferences and find the option for Orientation in the preferences window.

Generally speaking, a visible vertical line down your page after printing is an indication that the image drum in the machine may be damaged. It could also mean that the machine is reaching the end of its life.
When your printer leaves black lines, the lines indicate that there are excess toner powders on the rollers or transfer belt within the printer. As the paper is moved along by the rollers and transfer belt, any excess powder left on them can result in lines being left on the paper.
White lines will typically start appearing on your print outs due to a clogged up printer head. Your first port of call when solving this problem is to run the cleaning program on your printer, which should be accessible through its settings menu.
Lines or streaks always appear in printouts when the cartridges begin to run out of ink. Replace print cartridges that are out of ink or low on ink.
A vertical line is always a line that runs from top to bottom, or, from bottom to top. Standing lines are also a type of vertical line that runs vertically. We usually draw vertical lines between the bases of a trapezoid or a parallelogram….
Vertical Streaks or Lines

Vertical white lines also can signal an obstruction that prevents the laser from imaging pages correctly. Resolving that problem can require cleaning elements of the laser assembly or replacing it altogether.

The name of the tab where you set the printing preferences may vary depending on the printer you have installed, but it is generally called Setup or Page Setup. There should be a section labeled Orientation. Click on the Landscape radio button to change the mode to Landscape.
Partial prints are a common issue with printers and there are several main reasons it can occur: Problem with the print spooler (on Windows PCs) Overload of the GPU on later model Macs. Dodgy USB cord.
Because the perceived distance is larger than the perceived distance of the horizontal line, the vertical line appears longer.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.

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.
