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.
Dirty or misaligned print heads

Your printer may be printing fuzzy, blurry, or other faint text because of dirty print heads. All modern printers have a self-cleaning mode, which cleans the print heads, and additional internal equipment used in the printing process.

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.
If your laser printer is causing horizontal black lines you either have a problem with the optics or the drum. Cleaning the optics and replacing the drum should fix the problem in most cases.
One or more clogged nozzles preventing ink from getting to the page is the most common cause of a printer skipping lines. Through normal use, small amounts of ink can collect and dry in the printhead blocking the nozzles.
The most common cause of streaks on the paper are clogged print head nozzles. Due to the clogged nozzles, the ink can`t be transferred to the paper correctly.
If your printouts are blurry or smeared, try these solutions: Make sure your paper is not damp, curled, old, or loaded incorrectly in your product. Use a support sheet with special paper, or load special paper one sheet at a time. Make sure your paper meets the specifications for your product.
Print a cleaning page to remove dust and excess toner from the paper path if you are having any of the following problems: Specks of toner are on the printed pages. Toner is smearing on the printed pages.
Faulty and loose connections are the most common cause of horizontal lines on a TV. If you recently moved your TV, you might not have properly connected the cables. This is especially true if you`re using HDMI cables. Loose cables can easily slip out of their ports.
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.

HP CM2320fxi – Groaning / Vertical Lines
ANSWER : Sounds like you need a monochrome laser printer.
