HP LaserJet Emulation (Mode 6) N9 = 1, permanent PCL resources The printing system will store in memory all are protected. resources marked as permanent (soft fonts, macros, user patterns and symbol sets) and protect these resources during emulation switching. All resources marked as temporary (soft fonts, macros, user pat- terns, and symbol sets) will be lost during emulation switching. The print environment will be reset when it is returned to the mode 6 emulation. N9 = 2, permanent and temporary The printing system will store in memory all PCL resources are protected. resources, both temporary and permanent, and pro- tect them during emulation switching. Instead of resetting the mode 6 environment upon switching back, the printing system will restore the previous print environment. This option demands a large share of printing system memory. Resource protection becomes operational under any of the following emulation switching conditions: • An SEM command is sent to the printing system. • The emulation is changed by the user from the operator panel keys. • An automatic emulation sensing (AES) function is used for switching between KPDL and PCL. • An HP LaserJet PJL command @PJL ENTER LANGUAGE = ?? is received. The KPDL permanent dictionary is always protected, regardless of the values for N9. The amount of memory saved under resource protection is limited by the user memory available. Resource protection requires extra memory for storing downloaded fonts and macros. This memory requirement extends beyond the standard memory that accompanies the printing system. The requirement varies based upon optional features installed in the printing system. Note that a print environment using resource protection but whose space has been limited by user memory items like macros, symbol sets and fonts, will render the resource protection feature non-operational. The property value (temporary or permanent) assigned to a resource must be given in the PCL command language. PRESCRIBE provides no commands for making a temporary or permanent designation. As a result, resource protection mode applies only to those resources generated with the HP PCL command language. A description of the memory requirements and property values for typical models appear in the following table. Minimum memory requirement for Resource Protection The following tables are memory requirements for typical printing system models. For information on memory requirement on other printing system models, refer to the operation manual supplied with the printing system. Table 7.20.
