CHECKING THE INTERFACE BETWEEN THE PRINT SERVER AND THE PRINTER:
1. First make sure that the cable between the print server and the printer is securely plugged in at both sides.
2. Wait about two minutes after the printer is powered on and then run a printer self-test (see Section 2 for
information on how to run the self-test).
a. If the self-test does not print, then there is possibly a hardware problem. Double-check the connections.
If you still cannot print, then make sure that your printer is capable of printing text, PCL or PostScript (the
self-test will not work unless one of these is possible). Some examples of printers that do not support
direct printing of text files:
So-called Windows printers, usually low-end inkjet printers, perform all the image rasterization in
the printer driver, so the printer only understands a raw image file.
Many plotters only support HP-GL/2, RTL, or proprietary languages.
The only way to test such printers is to use an application program with the correct printer drivers.
3. It may be necessary to adjust the parallel port default settings in order to accommodate certain printers,
especially older ones, by using console commands (refer to Appendix A for information on commands, and
refer to Appendix B for information on using services). Do a SHOW PORT command to see the current port
settings.
Some printers require the pACKH hardware handshake. For these printers, use the command SET
PORT P1 ACKH ENABLED.
Some printers and applications do not work well if bidirectional communications are enabled. Use
the command SET PORT P1 BID DISABLED to disable bidirectional.
If you are using ECP mode with Okidata printers and a TROY PocketPro 100S print server, you
will need to enable software handshaking with the command SET PORT P1 SWIO ENABLED.
Not all printers support Fast Strobe mode, so make sure that FSTB is not enabled on the port if
you are having problems printing (Fast Strobe is disabled by default; use the command SET
PORT P1 FSTB DISABLED to disable it).
In some rare instances, disabling NBUF with the command SET PORT P1 NBUF DISABLED
will solve port compatibility issues.
