Depends on what you are using them for. As someone in the home services space, I can tell you I use local print shops all the time for swag, flyers and that sort of stuff all the time. And given how a lot of them respond to me, most of them seem pretty busy.

Most of what you would be buying is the customer list, and some equipment. I normally recommend for searchers to buy a business in a field they are knowledgeable in. If you have a specialty service you already know, selling and profiting off that will be much easier than at a print shop (usually). If you make a mistake because you are not good knowledgeable about printing operations and lose a large customer, you would be in a tough spot.
