Craden Peripherals DP8 technical manual Stops double height print

Page 18

ESC X mn sets left and right margins at columns m and n. Printing begins at column m and must stop at column n. The document may be no wider than (n+5)/10 in. as the n value limits carriage motion. This can increase throughput on narrow documents.

ESC [ @ followed by 04 00 00 00 m n hex selects double high and wide print. Double high print is set if the low order nibble of m is 2 and single high is set if it is 1. Double line feeding is set if the upper nibble of m is 2 and single line feeding is set if it is 1. Doublewide print is set if n is 2 and single wide is set if it is 1.

ESC [ I followed by 02 00 m n hex selects print pitches as follows:

10 cpi if m n = 00 0B, 12 cpi if m n = 01 EB, 17 cpi if m n = 01 ED 20 cpi if m n = 01 EE, 24 cpi if m n = 01 1E

Followed by 08 00 xx xx 00 m 01 00 xx xx hex selects print pitches as follows:

10 cpi if m = 90, 12 cpi if m = 78, 17 cpi if m = 54

ESC [ d followed by 01 00 n hex sets print quality to draft if 0<n<64, to normal if 63<n<128, to CQ if 127<n<255, or to default if n=255. No change occurs if n=0. Draft should not be used on passbooks. DP8 draft print quality may be degraded in the rightmost column (column 56 @ 10 cpi or column 67 @ 12 cpi).

ESC d followed by mn moves the next print position right by (256 X n + m)/120". Commands unique to C mode:

SI

stops double width character print.

ESC SO

starts double height print. All characters received before an ESC SI, CR or feed

 

command will be printed double height. Single height characters will be printed in

 

line with the top of double height characters if they are mixed in a print line.

ESC SI

stops double height print.

RS n

inserts n blank spaces into the print line and can be used to reduce the

 

characters transmitted when large blank spaces are to be printed. n is of the form

 

01NNNNNN where NNNNNN is the number of blanks to be inserted.

US

enables or disables underscoring of printable characters. All characters received

 

after a US and before another US, CR or feed command will be underscored.

DC4

clears all previously received data out of the buffer.

ESC ~ I

clears all previously received data and switches the interface to Mode I.

Commands unique to I mode:

BS

prints all preceding printable ASCII characters and positions the print pointer so the

 

next character will be printed over the last character.

HT

moves the print pointer to the next horizontal tab to the right if one is set.

SI

starts 17.1 character/inch printing.

DC2

stops 12 or 17.1 character/inch printing and returns to 10 cpi.

DC4

stops double width character print.

CAN

clears all previously received data out of the buffer.

ESC :

starts 12 character/inch print.

ESC D

nnnnn0 sets up to 28 horizontal tabs at each column n with each n being a single

 

binary coded byte and terminating with a 0 byte. ESC D 0 clears all horizontal tabs.

ESC R

sets all horizontal tabs to default values of column 9 and every eighth column to the

 

right and clears all vertical tabs.

ESC - n

starts continuous underscoring if n=1 and stops it if n=0.
