TrueImage Page Description Language (PDL)

TrueImage is the page description language (PDL) used in the TrueImage emulation. Instead of sending a string of characters and codes to the printer, the computer sends a file to DOC·IT in the form of a program that describes each page. A microprocessor on the DOC·IT controller runs the program that produces the printed page.

Developed by Microsoft, TrueImage is fully compatible with the Adobe PostScript TM Page Description Language (Level 1). This means that a document prepared for any PostScript-equipped printer will print properly on DOC·IT in TrueImage mode (provided it has the same fonts).

TrueImage is available for DOC·IT in two forms:

· TrueImage with 13 fonts (optional for DOC·IT 3000, standard on DOC·IT 4000)

· TrueImage with TrueImage Fonts Plus (optional for both models), having a total of 35 fonts

With 13 fonts, DOC·IT emulates the Apple ® LaserWriter ® II. With 35 fonts, DOC·IT emulates the Apple LaserWriter II NT. The TrueImage emulation can also handle Postscript fonts.
