Environment Variables used within the Printer Interface Script
A number of environment variables affect the operation of PShop (specifically,
the vvprint component). These are normally either unnecessary or set
automatically during installation, but you may want to change their default
values if you are customizing your system. An explanation of each environment
variable follows:
TMPDIR is the location of the temporary directory where FaxShop will store its
temporary files. When you load a document in the FaxShop client for viewing or
sending, you will typically need 50 KB of space for each full page of text, and
500 KB for each full page of graphics.Location of the temporary directory where
PShop will store its temporary files. You will need around 50 MB for a typical
single page color print job at 300 dip. You will need more space for multi-page
documents.
PRINTER is the name of the printer device driver PShop will use. If this is
specified, it must start with “-id=”. This is set to the full path of an ID file in
$VV_HOME/config for a non-SCSI/GPIB printer, or the SCSI or GPIB ID for a
SCSI/GPIB printer (in the form of “-id=s:bus:device” or “-id=g:bus:device”). If
left blank, PShop will try to automatically detect a supported SCSI or GPIB
printer. While this variable has the same name as the user shell-level environment
variable for lp and lpr, within the filter script its use is separate.
VVP_OPTIONS is a list of command-line options to pass to the vvprint
component of PShop. Please refer to Appendix A, “vvprint/vvlpr Commands &
Parameters”, for information about the options.
GSHOME is the location of the GhostScript executable. By default, this is
$VV_HOME/bin.
GS_LIB is the location of the GhostScript fonts and initialization files. By
default, this is $VV_HOME/ghostscript.
