Compaq 5525B/31/32 manual Configuring the PCL-II Emulation with Control Codes

Printer Feature Set Compatibility

NOTE: The SFCC is the Special Function Control Code. From the P-Series protocol, this code is selectable from the front panel. The default value is hex 01. For the Proprinter and Epson emulations, the SFCC is always the ESC (hex 1B) character.

Configuring the PCL-II Emulation with Control Codes

The remainder of this chapter describes the PCL-II printer control language codes that may be sent from a host computer attached to the printer.

The escape (ESC) control code is used to select most of the programmable features.

Commands and control codes sent from a host system override settings in the configuration menus. However, any configuration settings from host control codes will be gone once the printer is powered off (or reset to the default values). Host control codes are never reflected in the PCL-II configuration menu. In order to save a configuration, it is necessary to select the desired options from the front panel and save the options to one of the printers eight user-selectable configurations. The User’s Manual describes the menu option for saving changes to the printer memory.

Printer Feature Set Compatibility

PCL-II standardizes printer features and user access of these features, providing compatibility between HP printers. PCL-II is structured in five feature levels:

•	Level I	Print and Space
•	Level II	EDP
•	Level III	Word Processing
•	Level IV	Page Formatting
•	Level V	Enhanced Page Formatting

Each PCL level supersedes features of the levels below it. The 5525B/31/32 printers are Level II printers, meaning that all applications for Level I and II printers will operate correctly on your printer with no modifications.

In addition to supporting Level I and Level II features, the printer supports a limited set of additional features that may not be supported by other HP products. Applications written using these additional features may not operate as intended on other Hewlett-Packard printers which do not have these capabilities.
