stripped. A footer seems to be needed at the end of the PDL block.
Another unknown footer seems to be sent before

SCDIV
SCSYV
SCSNO # SerialNO (?)
SCSYS # some sort of state array? 22 fields. b19 is 1 when data can be sent?, b5 is 1 when printer busy?, b20:21 are 64 sometimes
SCMDS # MeDiaStatus: five 4-value hex numbers, last three decrease in unison (remaining prints). second one is 0100/0200/0300/0600, maybe Y/M/C/O?
SCPRS # PRinterStatus: (0000 = idle, 0002 = printing, 0005 = data xfer?)
SCSES
SCWTS
SCJBS # some sort of job count?
SCSYE
SCMDE # MeDia???
SCJBI
SCSYI
SCSVI # print counter(s)? (XXXXXXYYYYYY, and X = Y so far. SCSVI and SCMNI are identical so far)
SCMNI # print counter(s)? (see SCSVI)
SCCAI

SCGSI
SCMDI # MeDia???
