Screen Image Printing HP ALLBASE/4GL allows you to print an image of a screen by pressing CTRL and P followed by Return while the screen is displayed. The screen printing system uses the MPE/iXUX variable HP4SCREEN_PRINT to determine the destination printer.
NOTE You may also need to alter the HP4INV_PRT_CHAR MPE/iX variable. Refer to the description of this variable under "MPE/iX Variables" for details.
HP4SCREEN_PRINT Variable. If the HP4SCREEN_PRINT variable is not defined, HP ALLBASE/4GL prints screen images to device class LP. (The formal designator is HP4REP.) If HP4SCREEN_PRINT exists as an empty string (that is, ""), HP ALLBASE/4GL attempts to print screen images to a slave printer attached to the user's terminal. The terminal configuration must be correct for slave printing to operate. Refer to Terminal Configurations for more details.
NOTE If HP4SCREEN_PRINT is a non-null value, the screen image will not be printed.
The To System function key in the screen printing function key set also uses the HP4SCREEN_PRINT environment variable. The To Local function key always attempts to print the screen image to a terminal slave printer.
