Printer Modifiers

XFERSIZE n

This modifier specifies the maximum number of characters that can be sent to the

printer after an ACK is received and before the next ETX(ENQ) is sent.

A maximum safe value for n is the printer buffer size minus the printer high-water

mark. The printer high-water mark is the number of characters in the printer buffer that

causes the Data Terminal Ready (DTR) signal to become inactive. Check the manual

for the particular printer to determine what these two settings are for the printer.

XOFFCHAR n

This modifier specifies the character the serial printer uses to stop transmission from

the system. Use a different value from that specified for XONCHAR.

XONCHAR n

This modifier specifies the character the serial printer uses to restart transmission from

the system. Use a different value from that specified for XOFFCHAR.
