Introducing PCL compression method

The PCL Compression Method command (< ESc> *b M) determines how raster data is interpreted for the Transfer Raster Data by Row Block command (< ESc> *b w). The selected compression method stays in effect until explicitly changed by another PCL Compression Method command (< ESc> *b M) or until it is reset by an End Raster Data command (< ESc> *rc). See table below for a list of compression methods. TIFF rev 4.0 PackBits encoding (row-based) CCITT G3 one-dimensional encoding...

Using a disk file in a PCL job

The Alphanumeric ID command reads a file stored on the hard disk or floppy disk. With this command, the D640 reads the file into memory and treats this information as if it was part of the original print job. The result is similar to an include statement in a high-level programming language. The D640 does not do any special processing of the file, see Recommended Contents of Binary Data in the D640 Technical Reference Guide. The format of the Alphanumeric ID command is as follows ESC & n W...

Working with printer drivers

Application and printer driver settings influence the multiple-copies settings on the printer. To make sure you get the desired results, Hewlett-Packard recommends you test the multiple-copy features on the printer with your specific application and printer driver. Some things to remember about multiple, collated copies include Settings in the printer driver and application override settings on the printer's control panel. Commands in a print job override settings on the printer's control...
