Chapter 3: Printer Menus and Configuring Your Printer

EPC

The Early Print Complete parameter allows you to set up the printer data buffering scheme to emulate the 4234 data-handling characteristics. When this parameter is set to Off (the default), the printer emulates the buffering scheme of the IBM 4234 printer, which results in standard IBM 4234 error handling.

The printer notifies the host after it is finished processing the print buffer and is ready to accept more data. Then the host sends another buffer of up to 4K of data. This processing mode causes short pauses during the printing process due to the wait between notifying the host and the host sending the next buffer.

When this parameter is set to On, the printer notifies the host before it is finished processing the print buffer. This allows faster processing because the text buffer is set by the host before the current buffer is fully processed and there is no delay between processing one buffer and the next buffer. This processing mode speeds up data handling but may result in slightly different error handling.

GrAVM (Graphics AVM)

The Graphics AVM panel menu setup option only applies to the manner in which the Twinax AVM command is handled within a Code V, PGL, or Hex

Pass-Through graphics job.

A Tx/Cx Absolute Vertical Move (AVM) command moves the current print poition vertically (forward only) to a line number specified by the command without changing the horizontal print position. When the line number is less than the current line position the line is moved to the appropriate line position on the next page. When the line number is greater than the number of lines in the page (form length) an invalid range parameter errors. Tally provides two responses to the AVM command.

Style 1: The print position moves forward, relative to the last text item or paper-move command that preceded the AVM command.

The new line position is calculated by subtracting the height (in lines) of any graphic items preceding the AVM, from the line number specified in the AVM command. This style is intended for compatibility with printers that use an external or nonintegrated Twinax interface. This is the default setting.

Style 2: The print position moves forward to the exact line number specified by the AVM command. The presence or absence of graphic items preceding the AVM does not affect the position of text and/or graphics following the AVM.
