The lp spooler is not like a PC at all. There are no drivers since there is no printer metadata interface (a common language to describe printing actions like fonts and graphics and colors). Instead, the lp spooler uses a simple script to add features like a banner page or the ability to control line spacing. For HP printers, the options are extensive (landscape mode, 2up and 4up text printing, double sided, etc).
But for these 'dumb' printers, you would use SAM to add the printers to the spoolinng system and use (you guessed it) the dumb model script. That script can be customized but you probably don't need to if all you want is simple printing. Look at the scripts in /var/spool/lp/model and you'll see extensive support for HP printers.
As long asa you use the printers for plain ASCII text, all is well. Any printer features like larger or smaller fonts or changing the lines-per-inch, etc, will have to be imbedded into the file you print. To create some of the options you see in HP model scripts, you'll need technical reference manuals for the printers and some skills as a script writer.
As far as software goes, look at the Liverpool
