!PrinterLJ/ReadMe
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
This is PrinterLJ, version 1.12 (11-Jul-89)
The following remarks should be noted about this version of PrinterLJ and
its documentation.
Text printing is applied to files of types Text, Command, and Obey. For
anything else, the application checks if other applications know how to
print the file. If this fails it checks with the user whether to print the
file.
You can override the application's treatment of a particular type file by
setting system variables of the form Alias$@PrinterType_xxx, where xxx is
the appropriate type. If the variable exists, then the application performs
*@PrinterType_xxx <filename> before doing anything else. It then checks for
the existence of <Printer$Temp>. If this exists then it is printed. You can
therefore print via a print utility program by using:
*Set Alias$@PrintType_xxx *PrintUtil %0 -to <Printer$Temp>
Try looking at the !Boot files of !Draw and !Paint for some examples.
Clicking SELECT on the icon produces a window with data about the current
printer driver settings. Clicking on the name field steps through the
printers and dump modes enumerated in the file PrData. It also allows
control of the end-of-line control character sequence used in text printing,
which can vary between printers.
Clicking MENU on the icon produces a menu which allows the print destination
to be set, and the paper size to be altered. It should be noted that the
page size and margins supplied here must reflect the actual printable area
of the page, and cannot be used to alter the format of text printed as a
result of dragging text files onto the printer icon. The paper limits
are used to ensure correct positioning of graphics on the page, and are also
reported back to applications such as Draw for information purposes.
Printing can be speeded up by using the "monochrome" setting in the setup
window; this does, however, stop sprites and fonts being halftoned, and
reduces the range of halftone options available on other plotted items.
