Communication-attached printer

For a description of attachment methods, see Communication-attached devices.

The speed of the communication line can be the most important performance factor for a communication-attached printer. If multiple printers are attached to the same communication line or network path, the total capability of the network is shared and can limit printer throughput.

When PSF uses VTAM®, more processor usage is required than with channel attachment.

Table 1 shows the approximate maximum data rates that can be reached with the attachments listed. The rates that are shown are not always achievable. The results depend on network and system loading, tuning parameters, and the characters of the printer data stream. The attachment can limit printer throughput.
