Chapter 6 / Command Reference
• The first three parameters must all be included on the com-
mand line when ON is specified. OFF should be specified
alone. For example,
LPSETUP ON, 18M, 1
and
LPSETUP OFF
are valid commands, but
LPSETUP ON, IBM
is not.
• Each time LPSETUP is turned on, any previous escape codes
sent to a printer in IBM mode (or to LPDRVRSYS) that deal
with page length or perforation skip are cancelled. Otherwise,
there would be conflicts between the pagination attempted by
LPSETUP and that by the IBM printer or LPDRVRSYS. If
your printer is not IBM-compatible, and has been issued
escape codes an IBM printer would not understand, consult
your printer manual and cancel those codes to prevent the
same printer/LPSETUP pagination conflicts mentioned above.
In particular, use whatever code it takes to cancel skip
perforation.
• Each time you invoke LPSETUP with the ON parameter, the
line number is set to 1, and the page number is either set to
the page number value in the command line, or to 1 if you
omit that parameter. All other pagination settings (number of
lines per page, number of lines to skip over page perforation,
etc.) are not changed until a new escape code is issued for
that particular pagination setting.
• You must re-type the LPSETUP command each time the clock
inside your computer rolls over to a new 24-hour period (day)
to insure LPSETUP has the current date.
• If the parallel port number you specify is not available
(because the appropriate parallel board is not installed in
your machine), you will be told so, and the entire command
will be aborted!
