Lexmark Printer manual Forward and Backward Compatibility Modes for the Lexmark

2-10 PCL

You can also select fonts using PJL commands. The selection parameter is the number portion from the font identifier shown on the font sample pages, such as 0 or 76 from font identifiers R0 or R76. Use the PJL values shown in the tables beginning on page 2-15to select a symbol set. If a symbol set does not have a PJL value, use the symbol set ID to select the symbol set. A font selection can be either temporary or set as the default.

Use the following PJL commands to select fonts: FONTSOURCE, FONTNUMBER,

PITCH, PTSIZE, SYMSET, SET, DEFAULT. See Table 3-5: “Common Variables for

PCL Emulation” on page 3-48for more information about these commands.

Forward and Backward Compatibility Modes for the Lexmark X422

Your PCL emulation has forward and backward compatibility modes. The forward compatibility mode is used to emulate the fonts in the Hewlett-Packard Company’s LaserJet 4050. The backward compatibility mode is used for compatibility with the Hewlett-Packard Company’s LaserJet 5 and the Lexmark family of printers.

Standard PCL Emulation Fonts, OCR and Code 3 of 9 bar code fonts

Table 2-4 on page 2-10lists the font selection commands for forward and backward compatibility mode for each of the 47 standard PCL emulation fonts, the OCR and Code 3 of 9 bar code fonts. Since the font selection commands for the forward and backward compatibility modes are identical, they are listed together in the table. Most fonts are assigned a font group indicating which symbol sets that font supports.

To determine which symbol sets are supported by a particular font, find the font group (A, B, or C) for the font in Table 2-4,and then see Table 2-6 on page 2-15for the symbol sets that belong to that group.
