6. Is there paper in the printer?

7. Will your printer self-test” (see printer manual)?

The above will confirm that all physical connections have

been made correctly. If the test does not work, refer to the

instructions under “Installing the Grappler 9 Pin” on page 2.

Look at the printout to determine if all characters and functions

are being printed as they should be. If not, review the software

user’s guide to verify printer installation (if it is installation);then

re-check the Grappler DIP switch to see that it is in the correct

mode for the software in use (see page 5). If the printed

characters are still not correct, a final consideration would be

the PIN configeration as described under instruction number 6

of “Installing the Grappler 9 Pin” on page 3.

TROUBLESHOOTING - GRAPPLER 9 PIN

These are a few of the problems that might occur while

using the Grappler 9 Pin printer interface.

No Printing and/or "Garbage" Printing - Indicates that

printer selection is incorrect in the CHOOSER or the applica-

tion, the computer is sending incorrect serial data (baud rate,

stop bits, etc.), or that the GRAPPLER DlP switch has not been

correctly set. To recover, re-check both the printer selection

under your application’s SET UP and the GRAPPLER DIP

switch setting for your printer. See also: Graphics/Text switch

below, and instruction number 6 under ‘Installing the Grappler

9 Pin on page 3.

Graphics/Text Switch - Failure to reset GRAPPLER DIP

switch handle A in the parallel mode when changing printing

from text to graphics or from graphics to text may result in a

number of printing problems. If you attempt to print text when

switch A is in graphics position (ON), you may get italics or

certain printer graphics characters. If you attempt to print

graphics while switch A is in the test position (OFF), then you

may get thin white lines running through the graphics picture.

Set the GRAPPLER DIP switch in parallel mode for text or

graphics in accordance with the instructions on page 5.

White Horizontal Lines - Check the printer’s DIP switch.

Some printers have an option for controlling the eighth data bit

If this option is available, make sure your printer is set for EIGHT

data bits, If you are using the Grappler 9 Pin in parallel mode

and are printing graphics, failure to set switch D to the ON

position will also create horizontal white lines.
