The print-on-demand firm will produce collateral including binders, inserts, newsletters and colour training manuals.
DaimlerChrysler Services provides vehicle-related financial services for brands including Mercedes-Benz and Jeep. The printed material will be used at showrooms throughout the UK.
"We are finding that an increasing number of larger firms are utilising print-on-demand for low volume, short run material," said a Prontaprint spokesman.
"They often need marketing collateral turned out quickly because of the speed of change in certain sectors."
He added that money was also saved on areas such as transport and warehousing, although large clients continued to work with commercial printers for longer run work.
"DaimlerChrysler Services is a huge organisation in Milton Keynes so we are delighted that we are working with it," said Prontaprint Milton Keynes manager Colin Greaves.
