[iyonix-support] Canon cantankerousness

Various RO5.11 Iyonixes with !Printers v.1.72 and Canon bubblejets.
A long-standing irritation we have had with a BJC-4300 on a parallel-USB
cable, is the first printout after booting the computer is always lost. The
printer prints a single sheet with
[K
in the top left corner of the paper (that's open-square-bracket and capital
K). After this first failure, other prints proceed normally, so the hardware
connections are unlikely to be implicated. Previous to the Iyonix, the same
printer had worked fine on a normal parallel connection from a RiscPC.
In the neighbouring office, a newer Canon iP4200 on an almost identical
Iyonix, also fails to deliver a first print, but the circumstances differ
somewhat. This printer's USB port is driven by a D-Link network printserver
gizmo via LPR (v.2.00beta1 29.11.02) for convenience, though in practice only
the adjacent Iyonix uses it.
Once again, on first booting the Iyo, nothing will print to a Canon, but this
time it fails only if the iP4200 is set as the default printer (of several
others available on the icon bar). The act of physically /clicking/ the
Canon on the iconbar is needed to 'wake it up' as it were. By
experimentation, this can be done by momentarily deselecting the Canon then
reselecting it (which is hard to remember to do) or by ensuring the Canon is
/not/ the default, so the user has to click to highlight before using it. If
this is not done, the printer sits dormant and nothing prints; power-cycling
the printer makes no difference, it is the Iyonix state that is critical, and
whether or not a selection click has been made on that printer's icon since
Booting.
The printserver is ping-able at all times from any computer, including the
Iyo in question.
So it is pretty clear that both faults must lie in !Printers v. 1.72 or the
PDfiles (or possibly in RO 5.11 for the iP4200 only). It seems to eliminate
faults in the printer or printserver firmware.
(The default/non-default status has no effect on the BJC-4300 problem BTW.)
Anyone recognise this behaviour?
All our other printers (non-Canon) give no such problem, but since they are
all postscript lasers this doesn't help a lot with diagnosis. Well -erm- the
postscript photocopier /does/ give problem; it will only ever print single
sheets. (And guess what... its a Canon too- but that is sure to be a
red-herring.)

seem to have made it through to the Iyonix Freelist.
