Not knowing your printcap file, I can only guess you are using:
:/if=/usr/lbin/ppdof +Cln32.rpd
To preset the landscape and portrait fontsize in the printcap filter use:
:/if=/usr/lbin/ppdof +Ofs_l=11 +Ofs_p=8 +Cln32.ppd
:/of=/usr/lbin/ppdof +Ofs_l=11 +Ofs_p=8 +Cln32.ppd
At lpr command level use "-Ofs=12".
I realize these options are not documented in the ppdof, so I attached a document that was originally written to help implement the ppdof on V4.0F systems (where ppdof was not available).
Btw: Did you ask Minolta if they have a rpd
filter-file for theri KONICA 7145 ?
Have fun,
Johan.
