Anadex DP-9000 User Manual

where N equals an ASCII decimal number, causes an indent of
the number of horizontal dot positions equivalent to the
decimal value of the three numbers received. (Example: 3BH
30H 35H 30H causes an indent of 50 dot positions.) This
sequence may be sent immediately after the FS code or after
the line terminating code (NNNN); however, this sequence must
immediately precede a printable graphics byte, i.e., 40H
through 7FH. (See Appendix A for examples of Graphics coding.)
There is no wraparound feature in the graphics mode. Any
graphics bytes beyond the programmed printing width is trun-
cated. Caution is required here since the truncated codes
would include the termination and the printer could lock up.
There is no Form Length in the graphics mode; therefore, the
Top of Form and Form Length must be reestablished after exit-
ing the graphics mode.
If araphics are to be programmed and Option R is not installed,
each block of graphics instrpctions is limited to 600 graphic
bytes exclusive of the indent instruction and the FS and GS
control codes. If more than 600 graphic bytes are required to
complete a line of graphics printing, the following technique
should be followed. At the 600 byte point or sooner, close
the printing record with a 30H (decimal 0) which causes the
record to be cleared and printed without paper movement.
Transmit ;601 (or the correct decimal number for the current
print head position, plus 1, and transmit the remaining graphics
bytes. Using this technique will result in some loss of through-
put speed, but does permit printing graphics across the full
13.2 inches of form width, since 13.2 inches represent up to 990
graphics bytes and the available FIFO buffer is only 640-700
bytes, less a few bytes of overhead. Attempting to transmit a
single printing record of more than 600 bytes can cause the
printer to go BUSY with no way to terminate the record. In
this case, and if the Time-Out feature is disabled by Sl-7, the
printer cannot print and make more room in the buffer, and it
cannot time-out and clear 'the buffer.. The only way to "unlock"
the printer is to cycle power OFF and then ON again. If the
printer is in the Time Out mode, wait the 7~ seconds and the
data in the buffer will be printed, however this is an unrelia-
ble technique and data may be lost or modified.
The graphics mode is exited by receipt of ASCII control code GS.
