Autoprint; Line Densities; Data Buffering; Form Length Selection - Honeywell PRU7070 Handbook

Autoprint
When the full line length (80 printable characters at 10 cpi or 132 characters at
16.7 cpi for the PRU7070/7071 or at 132 or 220 characters at 10 cpi or 16.7 cpi for
the PRU7075/7076) is received without a carriage return/line feed command, the
printer immediately prints the line of data followed by an automatic line feed and
a column counter positioning to the first column.
After an autoprint execution, the first line feed received will be ignored ifnot
preceded by printable characters that are string-closed by a print command. This
eliminates the need for a LF when a full line is not ended by a CR plus LF or FF.
Attributes are not reset by autoprint.
Line Densities
The default value can be selected by means of an internal switch between 6 or 81pi.
These values can be overridden by software.
Down-loaded line density is saved when the printers are offline. The commands
cannot be embedded between printable data of the same line.
Line density changes must be made at the beginning of a message. The new form
length must be entered by software, otherwise page synchronization is lost on the
next form feed command.
Data Buffering
The two printer data buffers each provide room for 127 ASCII codes that can be
commands or printable characters. When the printer is placed offline, the buffer
content is saved and then printed after the online state is reentered.
Form Length Selection
Form length can be selected by an operator setting the easily accessible switches
(see Table A-2 in Appendix A). These lengths or other varying lengths can be
down-loaded via software commands, but they must be expressed in the number of
lines per form.
