I am trying to send an ESC sequence to set up letter qual mode
when I send the sequence specified in ROM man page 3-199
that is <ESC>[2"z it just prints the z and stays in draft mode.
What am I doing wrong?
Thanks for checking on this in advance!

It uses prt:. This example is similar. OPEN "prt:" FOR OUTPUT AS #4 esc$ = CHR$(27)+"[" den2$ = esc$+"2"+chr$(34)+"z" PRINT#4, den2$;"hello" 'Prints hello in NLQ CLOSE 4 I use prt: because LPT1: (used by LPRINT) eats initial sequences. If you are using C, then you are either doing something wrong or your printer doesn't support NLQ. Make sure you have the correct printer-specific driver selected in Preferences. It is the driver which converts the ISO sequences to printer-specific ones. You can test the sequences from CLI. Try typing the following. Everything typed between the first and last line will go to prt:. (Note: <RET> is the return key, <ESC> is the escape key) copy * to prt:<RET> <ESC>[2"zhello<RET> <ESC>[1"zhello<RET> CTRL-\ (Note - Hold CTRL and type \) With my MPS-1000, this prints "hello" twice, first in NLQ then normally. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Carolyn Scheppner -- CBM >>Amiga Technical Support<< UUCP ...{allegra,caip,ihnp4,seismo}!cbmvax!carolyn PHONE 215-431-9180 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Aha, the line eater strikes again. Thanks for the hint Carolyn I was uing Aztec C of the form: fh = fopen("prt:", "w"); fputs("\x1b[2\"z", fh); but I found out that if I use: fputs("some data for the line eater\x1b[2\"z", fh); it worked! I did some experimenting and found out that nulls didn't satisfy the old line eaters (or should I say ESC eater) appetite but linefeeds did. So be warned -- and Amiga printer driver guru's take note! BTW my printer program now works and if enough people are interested I can post it. It prints multiple files in background with wildcard selection and options for line numbers, headers, non-printing chars and other features. For example: pr -h *.c *.h -l manpage will print all c and h files with headers and the manpage in letter quality mode -- thanks for the help and send mail to Bob Leivian guest on mot!waycott -- John Waycott, Motorola Microsystems, Tempe, AZ, (602) 438-3164 {seismo!terak, trwrb!flkvax, utzoo!mnetor, ihnp4, attunix}!mot!waycott oakhill!mot!waycott@ut-sally.ARPA
