NOTE

If the active output protocol is generic and no 6 LPI string is specified, the PQ-8 will ignore all 6 LPI requests from the host.

COMMAND 85: 8 LPI STRING

Used with Generic output protocol to define the 8 LPI string. See command 84.

VALUE

DESCRIPTION

1(up to 25

Defines the 8 LPI

hex bytes)

string

1()

Deletes the 8 LPI

 

string

Example: &%Z85,1(1B 30) stores the 8 LPI command for an Epson LQ-2500 printer (hex value 1B 30) in the PQ-8’s memory.

COMMAND 86: 10 CPI STRING

Used with Generic output protocol to define the 10 CPI string. See command 84.

VALUE

DESCRIPTION

1(up to 25

Defines the 10 CPI

hex bytes)

string

1()

Deletes the 10 CPI

 

string

Example: &%Z86,1(1B 50) stores the 10 CPI command for an Epson LQ-2500 printer (hex value 1B 50) in the PQ-8’s memory.

PQ-8P, PQ-8S

COMMAND 87: 15 CPI STRING

Used with Generic output protocol to define the 15 CPI string. See command 84.

VALUE

DESCRIPTION

1(up to 25

Defines the 15 CPI

hex bytes)

string

1()

Deletes the 15 CPI

 

string

Example: &%Z87,1(1B 67) assigns the 15 CPI command for an Epson LQ-2500 printer (hex value 1B 67) in the PQ-8’s memory.

COMMAND 88: 12 CPI STRING

Used with Generic output protocol to define the 12 CPI string. See command 84.

VALUE

DESCRIPTION

1(up to 25

Defines the 12 CPI

hex bytes)

string

1()

Deletes the 12 CPI

 

string

Example: &%Z88,1(1B 4D) stores the 12 CPI command for an Epson LQ-2500 printer (hex value 1B 4D) in the PQ-8’s memory.
