Printer carriage control tape
Printer spacing may be performed by a skip-to-channel command in
which the control byte directs the printer to skip to the next hole
punched in a given channel of the carriage control tape. The control
byte may request a skip to channels 1 through 8, 10, and 11.
Skipping may be performed before or after printing the current line.
Note: A request to skip to channels 0, 9, or 12 through 15 is illegal
and should not appear on print tapes generated for standard US70
printers. US70 printers fitted with Special Forms Control F5278-10-
10, -30, however, can accept a skip to channel 0, 9, or 12 command,
and these control commands may appear on the print tapes.
The US70 carriage control conventions are shown in table 6-9.
The processing parameters for US70 carriage control are as follows:
CB Skip to channel 11 immediately, print, automatic upspace one line.
CC Skip to channel 11 immediately, print, automatic upspace one line.
