Why am I getting squiggly lines out of my printer?

Episode 1088 (1:15:13)

Sandra from Bellflower, CA
Epson Expression Printer

Sandra's Epson Expression printer has "squiggly lines" when she prints. Leo says that means the printer head needs to be replaced and frankly, it's cheaper to just buy a new printer. But if it's brand new, then she should take it back. She can try cleaning the heads with the software utility first, as well as the alignment routine. But if she's done all that, then Leo recommends taking it back.
