General Settings
Paper Low = Paper Out:
If set, paper low will not be reported until paper is out.
Inhibit Events:
If set, events will not be generated.
Error Events Asynchronous Mode Only:
Set to enable firing error events while in A-synchronous mode only. If not set, error events will be fired in both A-
synchronous and Synchronous modes.
Set Error String on Synchronous Error:
If set, the ErrorString will be set when an error occurs while calling a method in synchronous mode. Other wise it
will only be set in asynchronous mode.
Synchronous Time Out:
Time in milliseconds a synchronous print method will wait before returning a OPOS_E_TIMEOUT. If set to -1
(0xffffffff), a synchronous print method will never time out (default).
Synchronous Error Wait:
Time in milliseconds a synchronous print method will wait for an error condition to be removed before returning an
error. If the error condition is removed before this time has elapsed, the print method will be processed.
Performance
Background Status Updating:
If set, printer status will be updated in the background. This background updating will increase performance. This
performance increase is because when a print request is made the status is obtained from a previous background read
and not when the print method is called. Due to the fact that the parallel interface operates in half duplex, it is
especially important using a parallel interface.
Printer Never Busy:
If set, the printer service object (“driver”) will report that the printer is not/never busy. This will greatly increase
synchronous printing performance. Synchronous print calls will not wait for the printer to actually be idle. It should
be noted that this “never busy” mode is not strictly compliant with the OPOS specification. This performance
increase is especially important using a parallel interface, due to the fact that the parallel interface operates in half
duplex.
Communications Port:
Port Name:
This is the name of the communications port (ie. COM2, LPT1).
Setup Comm Port:
This will display a communications setup dialog. You will be able to set things such as baud rate and handshaking.
Note: these settings must match the printer you are using.
I/O Time Out Factor:
This controls how long the driver waits for I/O. Its value can range from 10 to 2000. The smaller this value is, the
more responsive the application will be when the printer is off or disconnected.
