CREATE CUSTOM PRINTER MODEL
Custom Driver
You can use this program to define custom printer models or drivers. Each
type of printer has its own characteristics; a laser printer needs to map
the print commands differently than a dot matrix style of printer. Use the
Custom Driver window to create different types of printer drivers.
The following sections detail the fields and their formats for the options
shown in the Custom Driver window.
Printer Model Name
The Printer Model Name is a unique name which refers to this particular
printer driver. This name is usually related to the model of printer, for
example a `Raven PR 9101' might be called rav9101. Enter the Printer Model
Name here.
Printer Description
This field can be used to give a brief description of the driver.
Printer Use
This field represents how the printer will be used. If it will be used for
printing text fields and graphic designs or charts, the interface will
have to include a graphic module. If the printer is only to be used for
text, then only the text module is required.
Using the left mouse button, click on the option button to display the
following list of options:
+ For Text Only (the default)
+ Text or Graphics
+ Other
If data sent to the printer will be already formatted for that printer, the
Text or Graphics selection should be chosen. This is typical of
applications such as word processors or drawing programs where the printer
type can be selected at print time. The application will then prepare its
output for the chosen printer.
If, however, the printer is to be used for the printing of plain text, then
the For Text Only selection should be chosen. If the text must be
manipulated before it is sent to the printer, you can use the OPTIONS
section to specify what pre-printing manipulations should occur. See the
following subsections for more details
Printer Interface
The Printer Interface defines what type of hardware interface is needed for
the printer to work properly. Different types of printers require different
types of interfaces. The interface may be:
+ Serial (the default)
+ Parallel
+ Data Products
+ Other
The most common of these is Serial or Parallel. Using the left mouse
button, click on the appropriate printer interface. Refer to your printer
manual for more information what interface is required.
If the printer interface selected is Serial, then additional information
will be required to properly setup the serial interface. The information
required is:
+ Baud rate - The speed at which the printer will send and receive
data. Click on the appropriate baud rate.
+ Parity - Select the parity the printer will be using. The options are
Odd, Even, or None.
+ Character Size - The size of the byte the printer uses. The two
options are 7 bit or 8 bits.
+ Stop Bits - The stop bits setting for the printer. The two options
are 1 bit or 2 bits.
+ Flow Control - This is how the printer recognizes signals from the
operating system. The flow control tells the system if the printer is
ready to receive information or if it is busy printing. This field is
hardware dependent on the serial boards installed in the machine.
Most serial printers use Xon/Xoff flow control.
Note: All of the flow control options are dependent on the serial board's
capabilities. Not all flow control options are supported on all serial
(TTY) boards.
Please check your printer manual for complete information regarding the
serial interface settings.
Options
You can use the options area for any pre-printing manipulation this custom
printer driver needs.
+ Printer type - Select the PostScript button if the printer is
running PostScript emulation. Otherwise select the ASCII button.
+ Include a banner page - An optional banner page can be added to
output to identify individual printer jobs by selecting the Yes
option.
+ Map NL to CR/NL - For some printer emulations, such as HPCL, the
carriage return (CR) character must be mapped to CR/NL (New line) for
proper output of lines of text. For these emulators, select the Yes
button.
+ Map lowercase to uppercase - Select Yes for printers which only
print in upper-case mode (typically band printers) or if you want
all upper-case output.
+ Additional form-feeds - When the print job is finished, the printer
driver will output up to five additional form feeds to advance the
paper.
The default value is zero. Enter or select a new value as desired.
+ Number of lines per page - Enter the number of lines of text for a
single page. This information is used in determining when a page
ends. The default value is 66. Enter or select a new value as needed.
+ Number of columns per page - Enter the number of characters to fit
onto a single line of text. This information is used in determining
where to wrap text to a new line. The default value is 80; enter or
select a new value as required.

model. Then you can assign it to a device in the Printer Configuration
window.
