Canon Laser printers need 1Mb of memory to print a full page of graphical print, i.e. text under MS Windows using TrueType fonts etc. Sometimes these printers are still supplied with 0.5Mb and therefore will only print ╜ a page. The only solution if this is the case is to contact your local Canon Dealer and arrange to get the printer upgraded to at least 1Mb of memory.

GDI printers are printers that directly access the Windows Subsystem to get the printing information and use the memory on the PC as its own processing memory.
Many of the GDI printers on the market will also emulate the HP Laserjet printer language PCL given the correct settings. If you experience any problems whilst printing from Sage Line 50 refer to your printer manual, or manufacturer, to find out if it is possible to set the printer to work as any other printer as this may solve the problem.
