MACRO DEFINITION A macro is a collection of printer commands, control codes and/or data created by the user that is downloaded and stored in the printer's memory. Once stored in the printer, a macro can be invoked by a single command. Macros can eliminate the need to download the same information repeatedly, thus saving transmission time. The number of macros that can be stored in the printer's memory is limited only by the amount of available memory (except in LJ II or earlier where 32 macros is the limit). Practical uses of macros include forms, letterhead, logos and lengthy printer commands.
MACRO CREATION STEPS
MACRO INVOCATION To invoke a macro, send the Macro ID command with
the ID number of the macro, then send the Macro Control command with a value
field of 2, 3, or 4 (Ec&f2X), (Ec&f3X), (Ec&f4X). This performs
the macro in the specified mode: 2 = Execute 3 = Call 4 = Overlay
THE PRINT ENVIRONMENT
DELETING MACROS There are several mechanisms provided by PCL macro control for explicit deletion of macros from user memory. These include commands to delete all macros, all temporary macros, or an individual macro by reference to its macro ID number. See the Macro Control Command. Both temporary and permanent macros are deleted from memory whenever the printer's power is turned off.
MACRO CONTROL COMMAND The macro control command provides mechanisms
for definition, invocation, and deletion of macros.
# = 0 Start macro definition (last ID specified)
# = 1 Stop macro definition
# = 2 Execute macro (last ID specified)
# = 3 Call Macro (last ID specified)
# = 4 Enable macro (last ID specified)
# = 5 Disable automatic overlay (last ID specified)
# = 6 Delete all macros
# = 7 Delete all temporary macros
# = 8 Delete macro (last ID specified)
# = 9 Make macro temporary (last ID specified)
# = 10 Make macro permanent (last ID specified)
* A macro may call or execute another macro, which in turn may call or execute another macro, two levels of nesting are allowed. When macros larger than 64K are stored in FLASM memory (SIMMs or DIMMs) the available levels may be reduced.
* Other than call and execute, no macro control operations may occur within a macro.
* A printer reset (EcE or UEL) is not allowed in a macro.
* The macro enabled for automatic overlay is invoked on each page, until the macro is disabled or deleted, a reset occurs (through software or control panel), or the page length, page size or orientation is changed.
* HP-GL/2 commands are only supported in a macro in the LaserJet 4 family and above.
* PCL macro control commands are not allowed while in HP-GL/2 context.
