CANON BJC-4000 a Genie post by Maurice Randall via SWRAP, Oct 97 Unlike the BJC-4100, the BJC-4000 does have dip switches and you can use it with your Commodore easier than you can the 4100. The dip switches are accessible from inside a cover on top of the printer. There are 13 switches numbered from 1 through 13. The main one is number 11. In the OFF position the printer is in BI mode and in the ON position it is in Epson mode. Here are the other settings while in BJ mode: 1 OFF=letter width ON=a4 width 2 OFF=normal ON=text scale mode 3 OFF=11 inch length ON=12 inch 4 OFF=character set 1 ON=character set 2 5,6,7 Set the character code page: OFF,OFF,OFF OFF,OFF,ON 850 OFF,ON,OFF 850 OFF,ON,ON 863 ON,OFF,OFF 865 ON,OFF,ON 850 ON,ON,OFF 850 ON,ON,ON 850 8 OFF=no auto linefeeds ON=linefeeds 9 OFF=normal ON=agm mode 10 OFF=64k buffer ON=31k plus 41k download buffer 12 OFF=normal ON=auto emulation switching mode 13 OFF=normal ON=smoothing Now when you turn switch 11 ON, the printer is in Epson mode and the differences are as follows: 3 not used 4 OFF=italics set ON=graphics set (characters) 5, 6, 7 international character set: OFF,OFF,OFF USA OFF,OFF,ON UK OFF,ON,OFF Germany OFF,ON,ON France ON,OFF,OFF Denmark ON,OFF,ON Sweden ON,ON,OFF Italy ON,ON,ON Spain 8,9,10 sets the typeface OFF,OFF,OFF Roman OFF,OFF,ON Sans Serif OFF,ON,OFF Draft OFF,ON,ON Courier ON,OFF,OFF Prestige ON,OFF,ON Script ON,ON,QFF Orator ON,ON,ON Orator-S Changing the positions of the switches only takes effect the next time you turn the printer ON. So, if you make a change, nothing will happen until you turn the printer OFF and then back ON. If you plan to use just text mode such as with Write Stuff, then Epson mode is recommended with switch 11 ON. Leave all other switches OFF unless you want to change the typeface with 8, 9, and 10. For programs that print graphics, try BJ mode with AGM turned ON. That would be all switches OFF except 9. This would help to simulate a 9-pin printer. If you have a printer driver that works with a 24 pin Epson, then use the Epson mode with all switches OFF except 11. In any mode you might want to experiment with switch 13 to turn the smoothing function ON. For some graphics that improves the appearance if the original is a low resolution image. For programs that can print in high resolution such as geoFAX, leave this turned OFF for best results. Also for geoFAX, use the BJ mode with the Canon driver to get the best prints. It is far superior to the Epson driver.
