Epson ESC/P2 Drivers for ProForma (ProWeSs system for Sinclair QL Home Computer)

            Epson (ESC/P2) Drivers for ProWesS (and ProForma)
            -------------------------------------------------

A former commercial package, these drivers are originally copyright RWAP Software 1999-2000, released as freeware as part of the 30th Anniversary of RWAP Software.

They are based on the original drivers provided by PROGS with their ProWeSs package for the Sinclair QL.

However, they have been much improved to allow 720 dpi printing and more speed. In particular the binary TIFF compression mode is now used to ensure that the minimum time possible is spent sending control codes to the printer.

These drivers should work on all Epson ESC/P2 drivers, although we understand that the Epson Stylus 200 does not support the binary commands used in these drivers.

There are three different drivers supplied:

Stylus_pfd A mono printer driver StylusColour_pfd A colour printer driver StylusColour2_pfd A colour replacement printer driver for LineDesign StylusMono600_pfd A mono printer driver for the Epson Stylus 600 StylusColourA5_pfd A second copy of StylusColour2_pfd

Under ProForma (the print program supplied with ProWesS, programs can use these drivers to output in all the colours supplied by your printer (unless the mono printer driver is used). However, LineDesign does not currently support colour (except on bitmaps).

To overcome this, colour replacement drivers are supplied which change some of the greyshades output by LineDesign to create colours.

ColourSample_ldp is a sample LineDesign file which allows you to see the various colours and their values under the colour replacement drivers. Remember that 0 is white and 100 is black. Anything other than the values listed will produce a grey shade based on the percentage of black.

StylusColourA5_pfd is supplied with the drivers renamed to:

Epson Stylus Colour 360dpi colrepA5 (etc)

  • this is so that you can have two versions of the colour replacement driver loaded at the same time, for example for different paper sizes.

INSTALLING THE DRIVERS

If you have already installed Stylus Colour Drivers on your system, you will need to replace the existing pfd files with those supplied. These are normally installed in the sub-directory win1_pws_pf_driv

If you have not done this before, then copy the files to this sub-directory.

You should then amend the file PROforma_cfg - normally in the sub-directory win1_pws_mine_

You can amend this in a text editor or selecting the Configure ProWesS option from the UTILITIES button. Select PROforma_cfg as the file to configure.

Once you have loaded PROforma_cfg, look for the line which says:

; load drivers (mixed screen, printer, bitmap & picture)

and then add the following three lines to this section (if not already existing):

D StylusColour_pfd D StylusColour2_pfd D Stylus_pfd

Each line will ensure that PROForma loads the relevent printer driver on startup.

You will need to reset your system for the new settings to take effect.

Updates

v1.00 First Release version

v1.01 ColourSample_ldp added

v1.02 Fast Monochrome mode added to the Mono drivers (this causes an error on the Epson Stylus 600 and possibly others, hence the separate driver) Improved Compression techniques used for 720dpi (Delta Row Compression) Generally increased speed.

v1.03 Corrected a bug in the 180 and 360 dpi colour printer drivers which meant that pages could get corrupted.

v1.04 Flush Buffers command added for later series Epson printers to ensure that end of page is printed. Memory allocation re-done to ensure that information is not corrupted between passes when using Delta Row compression. Machine code compression routines added to speed up transfer of data

v1.05 Updated the code for switching off microweave - for some reason PRINTS was adding an extra character
