3–45 Configuring the Printer
VFU (Vertical Format Unit) Select
The VFU Select feature controls how the printer handles vertical formatting.
•
EVFU: Enables the VFU and selects Printronix P-Series compatible
Electronic Vertical Format Unit (EVFU).
•
DVFU: Enables the VFU and selects Dataproducts-compatible Direct
Access Vertical Format Unit (DAVFU).
•
NVFU: Enables the VFU and selects Printronix P-Series compatible
New direct access Vertical Format Unit (NVFU).
•
CVFU: Enables the VFU and selects Centronics-compatible direct
access Vertical Format Unit (CVFU).
•
Disable: Disables all VFU processing.
The Programmer’s Reference Manual discusses the VFU in more detail.
NOTE: When the host computer has sent VFU data to the printer, and the
printer is on-line, it displays an “L” (for “Loaded”) in the lower
right corner of the message display. When the host has cleared the
VFU data (or has not sent any), no “L” is displayed.
When the VFU Select parameter is set to enable the VFU, and the
printer is on-line, the printer displays an “E” (for “Enabled”) in the
upper right corner of the message display. When the VFU is
disabled, no “E” is displayed.
NOTE: The choices above are available when the P-Series printer protocol
has been selected.
When the P-Series XQ printer protocol has been selected, only two
choices are available for the VFU Select feature: Enable and
Disable. In this case, with the VFU Select feature enabled, the
vertical formatting is the same as the EVFU choice above.
When the Serial Matrix printer protocol has been selected, the VFU
Select feature is not available.
