If you are printing to a Xerox laser printer, this information can help resolve printing problems. This describes how the Barr Host Communications Suite handles files with LPS Acronym for Laser Printer Series. A Xerox file format used for form overlays, fonts, or logos., Interpress A page description language from Xerox used on the 2700 and 9700 page printers (medium to large-scale laser printers)., Metacode, and LCDS Acronym for Line Condition Data Stream. An LCDS print job or print file is line data (text) with some text-based Xerox commands included, such as DJDE commands. file formats.
Files with these formats are usually created on a computer and sent to Xerox laser printers from BARR/PRINT to EPS. Printer resource files from the mainframe also can be in these formats at the host.
LPS files are used as form overlays, fonts, or logos. Typically, these resource files are created on the computer and then stored on the Xerox printer�s hard disk. When a file is sent to the printer, DJDEs in the print data tell the printer which resources to use.
LPS files are distinguished by a 128-byte file format header that contains the file name and file type. The number of bytes in the file is typically an integer multiple of 128. The following table describes the file header.

Because some print data (Xerox LCDS Acronym for Line Condition Data Stream. An LCDS print job or print file is line data (text) with some text-based Xerox commands included, such as DJDE commands. and Metacode A Xerox-generated data stream that provides all-points addressability on Xerox centralized printers. Metacode is a block variable, print file format similar to the mainframe format RECFM=VBM. Metacode files are generated with host and computer programs.) contains special formatting that would conflict with ASCII control characters, Barr Host Communications Suite must receive this data in one of the following formats: VBM or S/370.
