TEXT FEATURES
Before sending a character to the printer, the Grappler will
check the SELECT and PAPER EMPTY Status lines. If the printer is
not “online’, or is out of paper, a warning will be printed on
the screen and the Apple will beep. If this occurs check the
following:
1. The cable is firmly and properly attached to the printer.
2. The cable is firmly seated on the Grappler interface card.
3. The printer is on.
4. The printer is on-line.
5. There is paper in the printer. Note: The Grappler will
not check for paper on Epson printers.
6. The printer is set up for parallel operation. (Check
Appendix B of this manual for proper dip switch settings.)
Once the error condition has been corrected you may continue by
pressing the return key.
