zebra z4m PLUS label printer printing white streaks across the label?

Seeing the problem (i.e. a picture or in person) would help a lot.

Are the white streaks across the label or down the label?

Are you using a ribbon or thermal labels?

If the streaks are across the label (side to side), then you may have bad labels or ribbon (if ribbon is being used). Try a new set of labels or ribbon.

If the streaks are angled across the label, and you're using a ribbon, then your ribbon is not running true (straight) across the printhead and is "creasing" (actual term used) as it prints. You need to adjust certain components to straighten the ribbon as it passes through the printhead area. A qualified and trained tech should be able to correct this fairly easily.

If the streaks are straight down the label as it comes out, you may have a dirty printhead (the printhead is usually the dark brown section section as you look at the bottom). There may be ribbon material or other hardened material stuck on the surface. You can carefully try to clean it using some alcohol and a q-tip or some other soft, but firm, piece of material, including your fingernails, but do not use anything harder than your fingernail (still being careful) to try to remove any contaminants from the printhead as it will damage the printhead beyond repair. Again, a qualified and trained tech should be able to correct this fairly easily.

If there isn't any debris on the printhead, then most likely one or more of the printhead thermal elements inside are bad and the printhead will need to be replaced. They are not repairable, and usually cost around $300 or more. You may wish to have a qualified & trained tech replace it so as to avoid damaging the new printhead when installing, and it does require some setup when replacing.

All Epson R and RX series printers will print onto printable CD/DVD's. The other option is Lightscribe, but the DVD's you have will not work with Lightscribe. Lightscribe, laser-etches the picture/text onto the CD/DVD, but it is very expensive, monochrome and time consuming (mine takes about 30 minutes). My Epson is fast, colorful and cheaper then the Lightscribe. I highly recommend the Epson over Lightscribe.
