This had a seealso and two inline links to printing-inklevel. I removed printing-inklevel for 3.0. If it gets written, add the links back.
If your print-outs are streaky, faded, have lines on them that shouldn't be there, or are otherwise poor in quality, this may be due to a problem with the printer or a low ink/toner supply.
Fading text or images
You may be running out of ink or toner. Check your ink/toner supply and buy a new cartridge if necessary.
Streaks and lines
If you have an inkjet printer, the print head may be dirty or partially blocked. Try cleaning the print head (see the printer's manual for instructions).
Wrong colors
The printer may have run out of one color of ink or toner. Check your ink/toner supply and buy a new cartridge if necessary.
Jagged lines, or lines aren't straight
If lines on your print-out that should be straight turn out jagged, you may need to align the print head. See the printer's instruction manual for details on how to do this.
