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 PrinterPS, version 1.12 (11-Jul-89) Documentation on how to use PrinterPS and its associated printer driver module can be found in Edition 2 of the Archimedes User Guide and in the RISC OS User Guide. PrinterPS ========= The following remarks should be noted about this version of PrinterPS and its documentation. When a file is dropped on the printer driver application, a message is broadcast to all existing applications, asking them if they are able to print it. If no application responds to this, the printer driver then looks for a system variable of the form Alias$@PrintType_xxx, where xxx is the hexadecimal type of the file concerned. If it is found, it is used to load and run an application or other program which will do the printing. If the variable is not found, files of type PoScript (&FF5) are sent directly to the printer. Simple text printing is applied to files of types Text (&FFF), Command (&FFE) and Obey (&FEB). For all other file types, the printer driver checks with the user whether to print the file; if the reply is yes, simple text printing is used. If an application is found to print the file, either via the broadcast message or via the Alias$@PrintType variable, the printer driver checks for the existence of a file <Printer$Temp> afterwards. If it is found, it is sent directly to the printer if it is of type PoScript and printed as simple text otherwise. This usually results in the following behaviour: (1) PoScript files are sent directly to the printer. (2) Text, Command and Exec files are printed as simple text. (3) Most graphics applications' files will be printed by the application concerned, provided the application's !Boot file has been executed. (4) All other files are printed as simple text, provided the user confirms this. You can override this treatment of a particular type file by setting the system variables of the form Alias$@PrintType_xxx, provided no currently loaded application thinks it can print the file. If the variable exists, then the printer driver performs *@PrintType_xxx <filename> before doing anything else. This command can either output directly to the printer or put its output in the file <Printer$Temp>. If it does the latter, the printer driver will then transmit this file to the printer. For instance, if you have a print utility program "PrintUtil" whose output you prefer to the printer driver's for Text files, set Alias$@PrintType_FFF to the macro *PrintUtil <%0> -to <Printer$Temp>. If the result of the PrintUtil program is PostScript then you should set the type of <Printer$Temp> to PoScript in the macro or in PrintUtil; if it is straight text, you should set the type of <Printer$Temp> to Text. Clicking SELECT on the PrinterPS icon produces a window with data about the current printer driver settings. Clicking on the name field steps through the printers enumerated in the file PrData. Manual feed can also be selected, and options set that apply to simple text printing. The PrData file supplied with the printer driver provides settings for an Apple LaserWriter and for a generic colour PostScript printer. The former is totally accurate for an Apple LaserWriter, but can also be used as a generic monochrome PostScript printer. The PrData file can be edited to add to the set of printers if desired. Clicking MENU on the PrinterPS icon allows you to (a) see the version of the printer driver you've got; (b) choose between output to a file or to a serial, parallel or network printer; (c) choose the paper size you wish to use; (d) save your current choices in this menu and in the window brought up by clicking SELECT, so that they will be used by default when the application is started up again. If the output is to the serial line and XON/XOFF protocols are being used then a small module, SerialRxIgnore, is loaded and used to discard incoming characters (except XON/XOFF control characters). Simple text printing -------------------- This prints the file using the printer's fixed pitch Courier font, in one or more columns per page. It handles various characters as follows: Printable characters (ASCII 32-126 and 128-255): the appropriate character from Acorn's standard character encoding is printed. If the character isn't defined (this is currently true for character codes 128-142) or if your PostScript printer's Courier font doesn't contain the required character, an ellipsis character (a triple dot) is printed in its place. Line feed (LF = ASCII 10) and form feed (FF = ASCII 12) characters: these terminate lines. In addition, FF terminates the current column of output and starts a new one, starting a new page if there are no more columns on the current page. An LF/FF combination is treated as though it were a single FF. Other control characters (ASCII 0-9,11,13-31) and the DELETE character (ASCII 127): these are printed in the form "[<two hex digits>]" - e.g. the DELETE character is printed "[7F]". To distinguish them from ordinary characters, they are printed in bold. If a line overflows a column, it is wrapped round onto the next output line. A bold "|" is printed at the end of each incomplete output line to indicate that this has happened. Two output formats can be selected from the window brought up by clicking SELECT on the PrinterPS icon: (a) "Portrait": this prints the text in one column, using 10 point type and with the paper in portrait orientation. (b) "Landscape": this prints the text in two columns, using 7 point type and with the paper in landscape orientation. In addition, you can select whether you want a title printed at the top of each page of output. This title is printed using 10 point bold text, and contains the page number, the name of the file and the time of printing. Various additional options can be selected and/or changed by editing the PrData file. The printer driver module ========================= The following remarks should be noted about this version of the printer driver module and its documentation. For each RISC OS font used, the printer driver needs to be told which PostScript font to use in its place and the character encoding to be used for it. Near the end of the file !PrinterPS.PSprolog is a list of the font translations used. This can be added to or modified by the user as desired - usually, you should add a suitable translation for each new font you acquire. It is a good idea to ensure that the PostScript font you use has similar metrics to the RISC OS font: the PostScript code used for text printing will compensate automatically for differences between the metrics of the two fonts, but the results are likely to be ugly if these differences are too large. The file !PrinterPS.PSprolog also contains two PostScript encoding vectors (which say what actual character corresponds to each character code). One has been chosen to conform with the ISO 8859-1 Latin 1 alphabet as far as possible, though there are some ambiguities (e.g. character code &2D is defined in the ISO standard to be hyphen or minus, which are usually two different characters in PostScript fonts). The other is a special character encoding for the Selwyn font. Both encoding vectors can be edited if necessary - but make sure you know what you are doing. Not all PostScript fonts contain all the characters in the encoding vectors. The PostScript code in !PrinterPS.PSprolog is set up to ignore any character that you try to print if it doesn't appear in the PostScript font being used. If you would prefer a PostScript error to be generated instead, there is a commented single line change you can make to !PrinterPS.PSprolog to achieve this effect. Printing RISC OS sprites to PostScript is a rather complicated business and always generates quite a lot of PostScript output. It may also take quite a long time to print. Under some circumstances (particularly if there are a lot of colours in the sprite and/or if the sprite is to occupy a large amount of space on the printed page), the time taken by the printer and/or the application to print the sprite may become quite large (of the order of several minutes or even more). Do not worry unduly about this.
