Windows 95, NT 3.51, NT 4.0  CalComp PostScript Driver 4.16 Release     10 May 1998

This driver supports only PostScript for those models which support only PostScript or have a PostScript option, either internally or with an external PostScript option, e.g. a PrintBridge.  This often limits the output to Level 1 PostScript and rasterization on the plotter.   There is little user control of plotter features with this driver and performance is limited by the plotter.  It's usefulness is limited to smaller size and ease of network installation.  

Installation  

System requirements:
  - Windows 95, NT 3.51, or NT 4.0
  - 16 MEG of memory or more

The following assumes you have the CalComp PostScript Driver on a floppy disk.  If you have a self extracting archive, execute the archive and unpack the driver onto a floppy disk.   If you are installing from disk, all the files must be in the same folder.  If replacing a driver, remove existing printers using it and reboot.  Delete any printer bpd file corresponding to the PostScript Printer Definition file, ppd file, stored in (\Windows)\System, (\Winnt)\System32\ spool\drivers\w32x86 and w32x86\2, or walpha and walpha\2.  The following assumes you have administrative privileges to install a printer and have the Windows 95 or Windows NT 4.0 CD available for installation.  Even when doing network installs, the administrator should install the driver first and users afterwards.  Dec Alpha NT 3.51 users will need to make the substitution I386 -> Alpha near the end of the printer.inf file.  

Under Win95 and NT 4.0:

1.  Select Start / Settings / Printers.  
2.  Select Add Printer,  specify a port and Have Disk.  
3.  Insert the disk in drive a:, specify the location a:, and press Enter.
4.  Follow the instructions to complete the installation
5.  Configure the driver as desired.  

Under NT 3.51:

1.  In Program Manager, double click on Main and then on Print Manager
2.  Select the Printer / Create Printer menu option
3.  Insert the disk in drive a: and in the Driver list box, select Other.. (at the very end of the list)
4.  Follow the instructions to complete the installation
5. Configure the driver as desired.  

Windows 95 Notes
The inf file is used for installation.  This driver installs the following files to %SystemRoot%\system where %SystemRoot% is the Win95 system folder:  *.ppd, pscript.hlp, pscript.drv, pscript.ini, testps.txt, fonts.mfm, iconlib.dll. During installation all registry entries are made relative to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\.  During local installation registry entries are made to ~\Environments\Windows 4.0\Drivers, ~\Forms, and ~\Printers. The system must be rebooted after installation as the driver may already be loaded into memory.  

Windows NT Notes
The inf file is used for installation.  This driver installs the following files to %SystemRoot%\system32\spool\drivers\w32x86 and %SystemRoot%\system32\spool\drivers\w32x86\2 to during a local install and to %SystemRoot%\system32\spool\drivers\w32x86\2  during a network install where %SystemRoot% is the Winnt system folder:  *.ppd, pscrptui.dll, pscript.hlp, and pscript.dll.  A binary ppd file, bpd, is created in the process.  During installation all registry entries are made relative to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\.  During local installation registry entries are made to ~\Environments\Windows NT x86\Drivers\Version-2, ~\Forms, and ~\Printers.  During network installation registry entries are made to ~\Environments\Windows NT x86\Drivers\Version-2, ~\Forms, and ~\Providers\LanMan Print Services\Servers.  The system must be rebooted after installation as the driver may already be loaded into memory.  

Operation

During configuration, the user interface is provided by pscript.drv or pscrptui.dll based on a postscript printer definition (ppd) file for the device.  Both roll and cut sheet ppds are provided for devices supporting them.  During page layout, the driver, communicates the imageable area of a page to the application, based on the ppd file.  During printing it converts Windows GDI into PostScript and sends it to the printer.  

Changes

R 4.14  
Initial version.  

R 4.16
Corrected ppd model names for Win95 installation.

3.  Did you reboot after installation?  
4.  Does a local user installation succeed?
5.  Can a user print?
6.  Does copying a PostScript file to the port print?

Release Notes

This driver supports only PostScript.  The plotter must support PostScript, either internally or with an external PostScript option, e.g. a PrintBridge.  This often limits the output to Level 1 PostScript and rasterization on the plotter.   There is little user control of plotter features with this driver and performance is limited by the plotter.  It's usefulness is limited to smaller size and easier network installation.  

Problems

Incorrect PostScript bitmap color maps may be generated when using 64K video colors.
