The telecoms slump has hit Presstek, with subsidiary Lasertel expecting losses of around 2.2m ($3m) for the second quarter.
It prompted the parent to streamline Lasertel operations to focus on laser diodes supplied to Presstek.
Presstek said core business remained strong and it expected second-quarter revenues of up to 21m. But it faced "only marginal profits for the quarter".
Yearly business revenues should be around 90m.
