Help, does anyone know where i can get (or buy) a RiscOS
printer-driver for a Canon LBP-4 (LBP-8) laser printer.
Another solution would be a printer-driver where the format
of the actual print data output:
!PrinterDM generates : <ESC something> Number-of-bytes Hexbytes
(Hexbytes are one pixel wide and eighe high)
I need : <ESC something> Image-size Bytes/Line Hexbytes
(Hexbytes are eight pixels wide and one high)
Please, post reply to this group, if you have knowledge
of any program / sourcecode that might be useful.
Thanks, Dannie.ddevorchik@acorn.co.uk (David "dizzy" De Vorchik) (06/05/91)

Dannie, Try the !PrinterLJ driver this will output data as one byte for eight consecutive pixels. Although the most significant bit (bit 7) of the first byte of data corresponds to the first pixel within the line. You will need to process the data before sending it to the device as the command sequences sent by the LaserJet driver are bound into the code and cannot be changed by altering the PrData file (as with !PrinterDM). Here is a list of the sequences used by the driver: Page start: 27,"E",27,"&l",<number of copies>,"X" <anything defined in the system variable PDriver$LJextra> 27,"*t",<resolution>,"R" 27,"*p",<vertical skip>,"y",<horizonal skip>,"X" 27,"*r1A" Line start: 27,"*b",<number of bytes in line>,"W",<data> Page end: 27,"*rB" 12 27,"&a0C",27,"E" Key for non-obvious strings: <resolution> - horizontal resolution value (returned from PDriver_Info) <vertical skip> - defined in 1/300" <horizontal skip> - defined in 1/300" Hope this helps. --David -- David De Vorchik EMail: dvorchik@acorn.co.uk RISC OS Development Team Phone: (+44) 223 214411 Acorn Computers Ltd Fax: (+44) 223 214382 CAMBRIDGE England.

I believe there is a version for those printers. It uses a podule and drives the printer directly and so is very fast. Also all fonts are rendered correctly unlike on PostScript printers. TTFN, PMF
