4. What happens in short tear off mode There are two ways of operating the short tear off feature One way is to set the AUTO TEAR OFF option with SelecType When you have finished printing and if the perforation is at the top of form position the printer automatically feeds the perforation of the continuous paper to the tear off edge of the paper bail so you can tear off the last printed sheet When you resume printing the paper automatically feeds back to the loading position See the SelecType section in this chapter for instructions on setting the AUTO TEAR OFF option The other way of operating the short tear off feature is by using the TEAR OFF button on the control panel to feed the perforation of your continuous paper to the tear off edge of the printer After tearing off the paper press the TEAR OFF button again to feed the paper backward to the loading position um WARNING Do not use the tear off feature when you print labels Make sure that the SelecType AUTO TEAR OFF setting is off Otherwise labels may come off the backing and jam the printer Using the Printer 3 23 Short Tear Off The short tear off feature operated by the TEAR OFF button is described below 1 When you have finished printing press the TEAR OFF button once to feed the perforation of your page forward to the tear off edge of the paper bail 2 Tear off the page using the tear off edge of the paper bail 3 24 Using the Printer S

User defined Characters Run the program to see the printout below As you can see both sets of characters the original ROM characters that the printer normally uses and the user defined character set remain in the printer available for your use The command to switch between the two sets is used in line 90 and 110 It is ESC n If n is equal to 0 the normal ROM character set is selected this is the default If n is equal to 1 the user defined character set is selected If you select the user defined character set before you have defined any characters the command is ignored and the ROM characters will still be in use You may switch between character sets at any time even in the middle of a line To try it place semicolons at the end of lines 80 and 100 in the program above Copying ROM characters to RAM After running the program above if you select the user defined character set and try to print other characters the only one that will print is the arrow Since no other characters are in the printer s user defined RAM area nothing else prints Other characters sent to the printer do not even print as spaces it is as if they were not sent at all In many cases you may want to redefine only a few of the characters to suit your needs the rest of the alphabet will work fine as it is AS you have seen it is possible to switch back and forth at will between the normal character set and the user defined character
