Dot-Matrix Printer Check
Use this option to check:
l
The operation of your printer in IBM-compatibility mode
l
The compatibility of your printer with the extended character set used
by the Equity Ie
l
The ability of your printer to produce dot graphics and print images of
the graphics screen.
When you select option 14 from the DEVICE LIST, you see this prompt:
Is dot-matrix printer on-line (Y/N)?
Check
that your printer is connected to the computer, and that it is turned
on, loaded with paper, and on-line. Press Y and then
Enter
to continue, or
press
N
and
Enter
to return to the menu.
When you continue the test, the computer checks to see whether the printer
is responding correctly. This test detects whether the printer is off-line or
whether an interface error exists. If no errors occur, the computer sends a
repeating sequence of ASCII characters and dot graphics data to the printer
until you press any key. The pattern looks like this:
Text
Bit-image data
The text data includes all the characters commonly used by programs that
require foreign languages or graphic characters. If your printer prints
characters that are different from the ones you see in the illustration, you
may need to take care with certain software.
The dot graphics data is sent to the printer using a command (ESC K)
compatible with Epson and IBM printers. If this pattern is printed correctly,
you. can use the MS-DOS GRAPHICS or GRAPH24 program to print out
copies of graphics screens.
