Digi MIL-3000FTX manual Issues Regarding Bi-Directional Macintosh Printing

4.When the dialog box opens, choose the recently modified setup defaults file. The configuration page downloads.

5.Reset FastPort and print out a test page:

a.Put switch D1 down and switch D2 up.

b.Power cycle FastPort.

c.Put the switches back to their original position (D1 up, D2 up or down) after the test page prints.

6.Re-choose FastPort from the Chooser.

A Mac can now communicate directly with the printer connected to FastPort’s parallel port.

6.7.1Issues Regarding Bi-Directional Macintosh Printing

•Bi-directional printing may cause slower printing because of the extra queries that go back and forth.

•Some printers don’t support bi-directional printing on the parallel port.

Some Macs with parallel ports do not respond to queries on that parallel port. Check the printer’s documentation to verify that it supports IEEE 1284 bi-directional specification

•Some printing modes on certain FastPort models cannot support bi- directional printing.

FastPort devices support 3 or more handshaking modes on the parallel port. Users can modify these handshaking modes to speed up printing. However, with bi-directional printing, care must be taken to ensure that handshaking supports bi-directional printing. Table 6-2 shows the devices and the modes that support bi-directional printing:

Table 6-6: Support of Bi-directional on FastPort Print Servers

FastPort	Standard	FastDMA	Use ACK	FIFO-BUSY	FIFO-ACK
MIL-3100FTX	No	Yes*	Yes*	N/A	N/A
MIL-3200FTX	Yes	N/A	N/A	No	No
MIL-3310FTX	Yes	N/A	N/A	No	No

Note: *May only work with certain printer models.
