I found the commands that execute a2ps and ghostscript. I executed these commands on the command line and the printing process took the same amount of time as it did when I let apsfilter do the work. I did find though, that if i just use cat (cat <filename> > /dev/ltp0) to print an ascii text file it prints very fast...I don't know if this means anything or not... > Maybe apsfilter uses the wrong resolution for the printer ???

Depending on the resolution I used I would either get the same behavior I was getting or my printer would repeatedly draw in sheets of paper and immediately spit them out with nothing printed on them. This seemed like it would go on forever so I had to deque the job and turn off the printer. > But possibly you only have a hardware configuration error. > How many LPT devices do you have ? > Might there be an interrupt conflict with another device ? > Or possibly you have interrupt problems and might try > to configure the lpt driver to poll the lpt device ... I don't think this is a problem. Considering the fact that I was able to cat an ascii text file to the print device (/dev/lpt0 is my only print device) and the fact that the kernel configuration shows no device confilict, I don't think that is a problem. Any other ideas? Thanks alot, Jesse Troy jtroy@vt.edu
