Slow dosemu printing

[Linos <info@linos.es>]

Hello, i am using dosemu 1.3.4.0 and freedos to use an internal clipper
application in my point of sale systems, all works ok but barcode
printing, well it is not barcode problems, it works very well sending
raw format to the printer, the problem it is that when i send many
prints it is very slow, it takes a long time between prints (about 10
seconds) so if you have to print thousands of barcodes it is too slow, i
was using cups linux servers with samba and sending the jobs with
windows client machines so i know it is not a cups or pos app. problem,
i have no problem printing sells tickets because they are only one print
job for every sell, i have tried different ways of improve printing
speed without luck, the hogthreshold or the printer_timeout either
helps, i have tried to using this like print command $_lpt1 = "cat - >
/dev/lp0" to try to know if it is a cups problem, i would like to try to
do direct hardware access to see if dosemu prints faster than using
externals commands but i have problems with direct hardware access, i
have used this in my dosemu.conf:

$_ports = " device /dev/lp0 fast range 0x378 0x37a"
$_irqpassing = "7"

parport0 have this configuration in my test machine, and launched dosemu
with "dosemu -s" like root, but i dont know how to disable the use of
printers commands, it keeps trying printing redirection, if i comment
the $_lpt# lines it simply assumes defaults one so i can not disable,
any idea to speed up multiple printing jobs in dosemu? Thanks in advance.
