The printer manager formats and prints the following reports on either a locally attached
printer or a remote printer connected to the Instrument via the M3 Print Server:
• 7DEXODU7UHQG5HSRUW—The printer manager takes raw data from the trend module and
generates a formatted report. The user can specify whether to print short-term or long-term
trend data, and the period for which the data should be printed.
• (YHQW5HSRUW—The printer manager takes raw data from the event module and generates a
formatted event report. The user can specify a manual event, an alarm event, or a print
screen report.
• (YHQW/LVW5HSRUW—The printer manager takes the raw event list data from the events
module and generates a formatted event list report.
See Chapter 2, Installing the Instrument for more details on connecting to a printer.
A number of drawing functions support the printer manager and provide it with graphics
capabilities. The output from the printer manager is in PCL (Printer Command Language)
format, and is fed to the locally attached printer, which is connected via an infrared data link,
or to a remote printer. If the link to the printer is interrupted for a certain time, the printer
manager displays a prompt of the color LCD display, notifying the user.

The IrDA manager is responsible for sending raw data to the local printer in a format that
complies with the IrDA (Infrared Data Association) standard. The IrDA manager provides a
general printer device interface to the printer manager, and maps the general printer services
to the IrDA protocol. The general printer services are as follows:
• Establishing and terminating the printer connection.
• Transferring data to the printer.
• Retrieving the printer status.
The IrDA manager feeds the printer status (time out, paper out, and so on) back to the printer
manager, which in turn notifies the user of any errors in the print process.
