For printing an image file to a HP PaintJet XL, HP PaintJet XL300, HP DeskJet 1200C or HP DeskJet 1600C (not PostScript mode) ink jet printer, then
C:..> DIGIFILE image_file /FJ [output_file] [/NF] [/O output_lut]
[/X width] [/Y height] [/M margin]
[/W iw0 iw1 jw0 jw1] [/NB bit_planes]
[/R render_type] [/G gamma] [/T title]
[/D [buffer]] [/PT tray]
The /FJ
switch is used to indicate that the image file is being converted
for printing on a HP PaintJet series ink jet printer. If the optional
output_file
is not given, then the output will be written to the printer connected
to the parallel port. If output_file
is specified, then the output will be written to the file indicated.
This file may subsequently be printed using COPY
/B output_file LPT1 (or whichever other
port is required). Note that the switches may be present in any
order. The other (optional) switches have the following effects:
| Switch | Effect |
| /NF | If present, this switch suppresses the form feed which will normally be issued at the end of the plot. This will then enable a second or third image to be dumped onto the same page. |
| /O output_lut | This switch specifies the output look up table to be used for the screen dump. If the switch is not specified, then DigiFile will use the output look up table in use at the time the image was saved by DigImage. |
| /X width | If present, this switch specifies the width of the plot in mm. If this switch is not present but /Y is, then the width will be chosen automatically to maintain the aspect ratio. If neither /X or /Y are present, then the default will depend on how the image was saved. If the image was saved by [;DP Dump the screen to PaintJet printer file], then the width will be whatever was specified at that time. If the image were saved using the [;K: Save and restore buffer] menu, then the default width is 180 mm. |
| /Y height | If present, this switch specifies the height of the plot in mm. If this switch is not present but /X is, then the height will be chosen automatically to maintain the aspect ratio. If neither /X or /Y are present, then the default width is selected in the manner outlined for /X above and the height selected to maintain the aspect ratio. |
| /M margin | If present, this switch sets the left-hand margin, in mm, for the plot. If not present, then the default will depend on how the image was saved. If the image was saved by [;DP Dump the screen to PaintJet printer file], then the left margin will be whatever was specified at that time. If the image were saved using the [;K: Save and restore buffer] menu, then the margin is set to 200mm-width. |
| /W iw0 iw1 jw0 jw1 | This switch may be used to reduce the size of the window to be dumped to the printer. If not present, then the entire window contained in the file will be used. If the image file itself were saved as a window, then the top left corner of the image is loaded to coordinates 0,0 (not the original position of the window) and so the new sub-window coordinates should be relative to this. |
| /NB bit_planes | This switch sets the number of bit planes (1 to 8) to be rendered on the printer. If not present, then the default will depend on how the image was saved. If the image was saved by [;DP Dump the screen to PaintJet printer file], then the number of bit planes specified at that time will be used. If the image were saved using the [;K: Save and restore buffer] menu, then the default is eight bit planes. |
| /R render_type | If not included, DigiFile will use the Error diffusion (E) algorithm for producing the various colours and grey levels, or that specified by [;DP Dump the screen to PaintJet printer file] if the image were saved using this option. The rendering options are:
E Error diffusion O Ordered dithering C Clustered dithering S Snap to primaries (black, white, red, green, blue, yellow, magenta, cyan) |
| /G gamma | Specifies gamma correction to characterise nonlinearity between apparent colour/intensity and true colour/intensity. Default value (if /G not specified) is 1.5, or that specified by [;DP Dump the screen to PaintJet printer file] if the image were saved using this option.. |
| /T title | Specify title for plot. The text included after the /T switch up until the end of the line or the next / character is printed out above the screen dump. If the image were saved using [;DP Dump the screen to PaintJet printer file], then the title specified at this point will be used as the default. The default for [;K: Save and restore buffer] is no title. |
| /D [buffer] | If the /D switch is included by itself, then the image, once loaded, will be displayed on the computer monitor. If buffer is also included, then the image will be displayed on the frame grabber monitor using the specified buffer number. Note that this last option is the only one for which DigiFile requires the frame grabber card to be installed. |
| /PT tray | If included, then this switch will select a specific source for the paper. Valid values of tray are:0 Manual feed
1 Default tray |
