Traditional printing presses used to market their services by posting ads on the paper, have signboards on posts where foot and wheel traffic is common. For those companies who can afford it, they even go for air time through the radio or tv. Of course, word of mouth is always there and it is free. Some would get the latest yellow pages and call all possible prospects nearby. When technology has improved, others send faxes using the computer and all the fax numbers queued in so that they can fax while they sleep. With the internet, this time, a printing press must have a website and a software to accommodate orders 24/7. You can compare online print ordering software to see what suits your needs.
