These files are printer drivers for the Protel Autotrax, Easytrax and dos schematic products. These drivers were developed by Matthias Hartl email@example.com, modified by Ed (Eds webpage: http://www.alphalink.com.au/~edsa/), and are open source. The existing protel printer drivers will only print to postscript, HP and some epson formats. Using the modified drivers here, it is possible to save PCBs and Circuits as images that can then be emailed, put on web pages, or printed using ANY windows printer.
To use one of these drivers, copy it into your existing printer driver directory. You will then see a new printer come up, such as "PCX 100dpi A3/A4". Select this printer. Select "Setup"..."Printer" set the device to file and refer to the other settings below. After you have printed your PCB/Circuit, you will find the image file saved as the filename you selected.
PCB: Plot will overwrite the file extension with .RCK or something similar, you will need to rename to xxx.pcx
The most efficient format to use for schematic and PCB images is
The .GIF format is compact and can be viewed directly by most internet browsers and email packages. These printer drivers produce PCX format images - to translate to another image type (for instance .GIF) or change it from normal to negative, or rotate or scale it, use any graphics package. A very good program to use for this is the unbeatable free graphics package irfanview.
You can also specify if the driver is to save in Positive or Negative
format (for instance, for reversing the image to make a PCB negative)
by using an environment variable:
SET PCXDRV=NEG or
Just a few important Notes:
The circuit/PCB should fit on "one sheet of paper". Although the output is an image, it is being produced from a DOS program printer driver - an unfortunate limitation is that the original image must fit on one "virtual sheet of paper" or else the image file will be corrupt. You should scale any PCB that is larger than the A3/A4 paper size.
Output MUST be directed to a file - you must set the "device" in your plot program to a filename, (preferably one ending in .pcx) and not "Serial Port 1" or "Parallel Port 1" that is the normal default.
When Printing PCX files to paper, don't rely on a windows printer driver to correctly scale the image - use a graphics program such as irfanview and specifically set the scaling, for example, to 300dpi, (or by experiment) so that your PCB size is accurately reproduced.
