Chapter 7 - Controlling the Printer Using the Keypad in Immediate Mode When a printer has been placed in Immediate Mode (by sending an IMMEDIATE ON statement), these keys on the printer keypad work as follows: • The Print key or button produces a FORMFEED operation. If the printhead is lifted, pressing Print produces a CLEANFEED operation, which runs the platen roller several times to facilitate cleaning. During batch printing, pressing Print interrupts or resumes printing. Note: In Immediate Mode, Print can also start a print job if the key has been enabled using a PRINT KEY ON statement. For more information, see "Enabling Manual Printing With PRINT KEY ON" on page 107. • Pause interrupts or resumes batch printing. • Feed works the same way as the Print key. • Pressing Shift + Feed at the same time produces a TESTFEED operation. • Setup places the printer in Setup Mode. • Pressing i displays information on the communication channels. The left and right arrow keys toggle between communcations channels when channel information is displayed. Using the Printer Display Fingerprint provides a number of commands you can use to control the printer display on the PF/PM/PX-series and PD42 printers. The PF/PM/PX-series printers have a 2 × 16- character display, which Fingerprint can control programmatically. The display is provided with a controllable cursor. The PD42 printer display includes: • a text area that shows operating messages much like other printers. • a state area that shows icons representing various printer operating states, such as Setup Mode, Pause, or Dump Mode. • a graphical area that shows various images (primarily error messages) and information strings. • a "soft key" area that shows pictograms related to the PD42 soft keys. When the printer is placed in Setup Mode, the character set is automatically switched to US-ASCII. When the printer exits Setup Mode, the previous mapping is restored. Printing Text to the Display on PF/PM/PX-Series Printers Note: This section applies to the PF/PM/PX-series printers. This example shows how to print text to the printer display. Before you can print any text to the display, it must be opened for sequential output as follows: 114 Intermec Fingerprint Developer's Guide
