[From equivalent
EP0469974A2]
A printer (10) which receives from a host computer (11) through a part (12) print jobs encoded in any one of several printer control languages. The printer (10) comprises a printer controller (13) and has the capability of interpreting print jobs in each printer control language. The printer (10) samples a portion of each print job and, using a resident algorithm and data sets obtained by statistical techniques, analyzes the sampled portion of the print job to identify the printer control language in which the print job is encoded.

1. A printer for receiving an input stream of electrical signals defining a print job from a host computer encoded by a computer application in any one of a plurality of printer control languages, said printer control languages being characterized by n-grams which are one or more distinct character codes concatenated in a fixed order, said printer comprising means for interpreting each of said plurality of printer control languages to define a bit mapped image, means for converting the bit mapped image into a visual display of said image, a sampling circuit for capturing a portion of any input stream, means for identifying the printer control language in which the captured portion of the input stream is coded, and a circuit for directing the interpreting means to interpret the input stream in accordance with the identified printer control language, characterized in that the identifying means comprise a microprocessor with a resident algorithm and a plurality of data sets stored therein, said data sets being obtained by statistical techniques, for analyzing the captured portion of the input stream, there being at least one data set for each printer control language.
