Printing Modes There are two fundamental printing modes with mobile printers.

A. ASCII Based Print Jobs The host sends the print job as a series of lines of characters, some of which represent the text to be printed, while other portions are command codes which tell the printer which font to use, where to locate the text, what barcodes to use, etc. These text-based files are encoded in a print language specific to the target printer. The DP-541 understands ASCII based jobs in several different print languages. Refer to the Appendix or the /ntegrator's Guide for the list of print languages supported. B. Graphic Based Print Jobs The host assembles the printed image as a series of lines of dots, and transmits this image as a sequence of data bytes that represent the dot patterns assembled. Often these jobs or files have some control characters on the front end and / or rear end of the dot pattern bytes to define their format, help control pagination, etc. Windows drivers in particular encode the image as a graphic based print job before it is passed along to the printer. In addition to accepting graphic jobs from its Windows driver, the DP-541 can accept and print directly many other graphic image file types. This opens up the option to print job images from a variety of devices for which drivers or print utilities don't exist, such as some tablets and smartphones. Please see the /ntegrator's Guide or your system integrator for more details. www.dascom.com
