SUBROUTINE VBDRIV(IFUNC,RBUF,NBUF,CHR,LCHR)
INTEGER IFUNC, NBUF, LCHR
REAL RBUF(*)
CHARACTER CHR*(*)
C
C PGPLOT driver for Canon Laser printer. PORTRAIT MODE.
C
C Supported device: Canon LBP-8/A2 Laser printer.
C Conforms to ISO646,2022,2375 and 6429 specifications.
C VDM (graphics) conforms to proposed American National
C Standard VDM mode.
C
C Device type code: /VBCanon (portrait mode only).
C
C Default file name: PGPLOT.CAN
C
C Default view surface dimensions: 24 cm by 19 cm.
C
C Resolution: 300 pixels per inch in both directions.
C
C Color capability: Color indices 0 (erase) and 1 (black) are
C supported. Note, hardware polygon fill is used and colors
C 0-11 control the fill pattern.
C
C Input capability: None.
C
C File format: Variable length records with Carriage control
C of LIST.
C
C Obtaining hardcopy: If printer is connected to a terminal
C line (RS-232 option) then printing the file on the corresponding
C queue should suffice. If the printer is connected using
C the Centronics interface, which appears the to VAX as an
C LP device, then it is important to ensure that (1) all 8 bit
C characters are passed to the printer (2) lines longer than
C 132 bytes are not truncated, and (3) no extra formatting
C commands (e.g. form-feeds) are sent to the printer.
C This can be done with the VMS command:
C $ SET PRINT/PASSALL/LOWER/CR <device>
C Note, some interface boards have a option to append a carriage
C return after a formfeed or LF character, it is suggested
C that this be disabled.
C The file should be printed with the /PASSALL qualifier i.e.,
C $ PRINT/PASSALL <filename>
C Note, SET PRINT/PASSALL and PRINT/PASSALL do not do the
C same things and hence PASSALL is required in both locations.
C
C 27-Jan-1988 - Version can be sent over BITNET (I hope) [AFT].
C 27-Sep-1986 - Add color index 0 (erase) [AFT].
C 5-Aug-1986 - [AFT].
