slap is a UNIX print-driver program for all models of
Seiko Instruments'
Smart Label Printer®.
Seiko Instruments do not provide software or drivers for
UNIX platforms. But I do!
The current release of slap is
2.4.4, dated 9th February 2001.
Latest News - version 2.4.4
NOTE:
Some recent Linux distributions attempt to optimise CPU-usage
for serial-port communications by delaying processing of incoming characters
an extra 5-10 milliseconds. This optimisation breaks slap.
The fix is to configure
the serial port for "normal" operation using the Linux setserial program:
setserial low_latency /dev/....
Added baud-rate mapping schemes to enable
use of SLP-100, SLP-200 and SLP-240
printers on (some) platforms that do not provide 57600 baud facility in their
native programming interfaces. Also fixed typos that prevented compilation
on all such systems.
Fixed occasional comms crash for SLP-EZ30, SLP-Plus and SLP printers.
Fixed "missing last half-dot" for SLP-EZ30, SLP-Plus and SLP printers.
Fixed theoretical sequencing bug in the recovery-from-printer-error
logic.
Added documents describing how to use additional fonts with slap,
and how to print barcodes.
Coming Next!
Full modularisation into separate programs: low-level bitmap printer,
text-rendering front-ends for various font types, GUI front-ends,
and so on. This will also enable full
PostScript capabilities, by using GhostScript as a preprocessor.
Thanks to Andreas Kostyrka and
Don Smith for ideas and inspiration.
