The sales clerk at Staples recently talked me into buying the Staples brand black ink cartridge for my Lexmark at a slightly lower cost than the Lexmark brand, claiming theirs had much more ink and would last longer.
I put the new cartridge in the night before last and it ran out last night right in the middle of a batch of coffee bag labels, ruining about half of them (since I wasn't paying attention). I'm pissed. Granted, I was doing some heavy duty printing between labels and brochures but no more than I'd been doing the past week or two with the Lexmark cartridge.
The brochures eat a lot of ink so I got a price for Staples to print them for me. .78 cents apiece for two-sided color trifold! I think that comes out to much more than Lexmark ink cartridges. I need to find a good print shop.
