[BL] BL2 won't print or scroll in console mode

Disabling lp1 onboard (it was set to the same address and IRQ as the MDA 
card's parport) made one difference:  When I typed
cat filename.txt > /dev/lp0
it did not just move to the next line (blank) but also gave me
a new prompt.  Nothing printed.

I will see if I have an MDA card with no parport, or one that I can 
disable easily.

I still cannot print my pdf files without them being shifted over.  I 
tried in DOS with gs 5.10 on both pdf and ps files, and with deskjet 500 
and Panasonic dot-matrix printers.  Can't figure out how to print with 
psview on the Panasonic.  Or how to convert a pdf or ps file to a straight 
image - is there a way?  pdfimages could not handle this, error messages.

I can read the files with a text editor and there is one section (after 
all the junk about fonts and colors) where the image appears as a string 
of characters.  Can this be converted (easily) to a plain tiff?  Or even 
gif or png?  What format does pdf use?  

I can't print with xpdf because I can't run Xvesa as 'user' - what do I 
need to do for that?

I will try gs 8.14 in Win98 if I get tired of reading tiny text on the 
screen with bmv (.ps reader).  

I bet the rest of you are loafing this weekend instead of working like us 
self-employed people.  

Is there some way to print with xpdf from the command line (not having to 
load X first)?  Does BL3 Xvesa work for 'user' not just root?
