[nabs-l] embossing problem: any help?

[Dennis Clark]

Hello,
This is just a guess.  I think the handshaking between your printer and 
computer are not set correctly or are not functioning.  The computer can 
send data to your printer much faster than your printer can print. 
Handshaking is the way the printer tells the computer once the printers 
buffer is full, to pause sending data until the printer empties its buffer 
and gets caught up.  At that point the printer tells the computer that it 
has caught up, so send some more data until the printer again tells the 
computer to stop sending.

There are 2 kinds of handshaking, hardware and software.  Hardware 
handshaking is done over 2 wires in the cable which connects to the printer. 
Software handshaking is done by the printer sending a particular computer 
character, control x or control y, to the computer, which essentially says, 
please send data, or please stop sending data until I get caught up.

Both the computer and printer need to be set to use handshaking, and they 
each need to be set to use the same handshaking, either hardware or 
software.  Did this ever work correctly, and if so, what might have happened 
which could have cause any settings to have been changed?  Please feel free 
to send me more information or questions.
Best,
Dennis
