The forward agreed to terms on a five-year contract with the Flyers on Sunday before a broken printer kept him from signing right away.
"It's not official," Flyers general manager Ron Hextall said. "We announced that we'd agreed. [Van Riemsdyk has] got some printer problem."
Van Riemsdyk said the printer in his condo wasn't working and there was an issue with one downstairs in his building. He was able to sign the contract later Sunday.
"Took a little bit of time," van Riemsdyk said. "But [I] finally have it done, which is nice."
Van Riemsdyk was selected by Philadelphia at No. 2 in the 2007 NHL Draft and played his first three NHL seasons for the Flyers before being traded to the Toronto Maple Leafs on June 23, 2012. He played the past six seasons for Toronto.
