DC 1

Selects printer.

In IBM mode, this command causes the printer to be enabled after it has been

disabled by an ESC Q {35} command. In EPSON mode, this command causes the

printer to be enabled after it has been disabled by DC3 code (the SELECTIN

signal was HIGH). The SELECT signal goes high and the characters between DC3

and DC1 codes are discarded. If you selected SLCT IN (VALID set) in the Printer

Setup, the DC1 code is ignored.

DC 3

Deselects printer (only EPSON mode).

If you send this command when the SELECTIN signal is high, it causes the printer

to be disabled so that the SELECTIN signal goes low and the characters between

DC3 and DC1 codes are discarded. If the SELECTIN signal is low or if you

selected SLCT-IN (VALIDset)in the Printer Setup, the DC3 code is ignored.

ESC Q {35} {36}

Deselects printer (only IBM mode).

1B 51 {23}{24}

mode).

1B 78 {n}

27 120 {n}

1B 49 {n}

27 73 {n}
