LP 6 (260-1166)                   Buffer               Faxback Doc. # 5936

The Printer starts a Print cycle under any of the following conditions.

A) Data buffer receives the 132nd character.
   Normal width characters and elongated characters can be sent together.
   An elongated character is counted as two characters. In case the 132nd 
   character is an elongated one, the elongated character corresponding to
   the 132nd (and 133rd) character is printed at the start of the next line.
   In the condensed mode the Printer will start printing on receipt of the
   132nd character; however, the next condensed character will be printed
   on the same line. On receipt of the 198th character (in the condensed
   mode), printing will continue as noted above.

B) When print data for at least one character is in the buffer and carriage
   return or line feed code is received.

C) When print data for at least one character is in the buffer and the next
   data is not received within approximately one second.

D) With normal or elongated mode specified, when condensed character command
   is received (CHR$(27)l CHR$(14).

* In this case after all the data in the buffer is printed the carriage 
  will return to beginning of the line before printing the condensed 
  characters which follow. Without special care in programming insertion of
  a CON STR command in the middle of a line will cause over-printing of 
  characters.

E) With condensed mode selected, when condensed mode cancellation code is 
   received (CHR$(27);CHR$(15)).

* In this case after all data in the buffer is printed, the carriage will
  return to beginning of the line before continuing to print the characters
  which may follow. Condensed characters should not be combined with other
  modes in thee same line without special programming care.

NOTE: While in the elongated character mode and if an "elongated character
mode code" is received, or while in normal character mode and an "elongated
character mode cancellation code" is received, or while in or condensed
character mode and "condensed character mode code" is received, or while in
normal character mode and "condensed character cancellation code" is
received. When a CR or LF code is received and after completing operation,
a second "CR code" is again received.

All of the above codes in parenthesis (repetition of existing states) codes
will be ignored.

* You can have your printer changed so that CR code is not ignored after 
receiving CR or LF code. For details, see your Radio Shack store or 
Computer Center.

F) When Bold Character mode has not been set and the bold character 
designation is received, and the data buffer has at least one character. If
previous character(s) was condensed or elongated, the following characters
will be handled the same way and thee bold character cancel code is
received, with at least one character in the data buffer. The next
character (normal mode) will be printed in sequence on the same line.

NOTE: Under the following conditions, the codes enclosed in parenthesis
will be ignored:

  * When elongated character is designated and "ELN Code" is received.
  * When elongated character is not designated and "NOR Code" is received.
  * When condensed character is designated and "CON STR Code" is received.
  * When condensed character is not designated and "CON END Code" is
    received.
  * When bold character is designated and "BOLD STR Code" is received.
  * When bold character is not designated and "BOLD END Code" is received.
  * When CR or LF is received and after completing operation, "CR Code" is
    again received.
