Barcode Darkmode
• Enable (default). The barcodes are printed at a higher 
resolution.
• Disable. The barcodes are printed at lower resolution but at a 
higher speed.
PUM Default
This is the Unit of Measure (UOM) as it is used within the ANSI 
emulation. Coordinates received in ESC sequences can be sent in 
two UOMs:
• Decipoints (default). A unit of 1/720 inch
• Lines or columns. Uses the current LPI and CPI values.
The UOM used is determined by this configuration setting.
Truncate PI Slew
• Truncate at TOF (default). The slew is terminated when the 
next Top-of-Form is reached. (This function applies to the ANSI 
EVFU only.)
• Disable. PI slews will be completed independent of their 
length.
ETX/ACK
End of Text/Acknowledge. The host controls the flow of 
communcation to the printer by sending a block of data and ending 
the block with an End of Text (ETX) signal. When the printer 
receives the ETX signal, it acknowledges the ETX, thereby 
acknowledging it has received the entire block of data.
• Disable (default)
• Immediate
• Afterprint
