NOTE: If you protect a roll, then later unload the current roll and load a new one, the new roll
remains protected. You are protecting the roll number, not one specific roll of paper. That roll number
will remain protected until you cancel the protection.
TIP: If you print without specifying a roll number or paper type, you will not be able to print on any
protected roll.
Unattended printing/overnight printing (T1200 series
only)
The HP Designjet T1200 printer series, with multiple rolls, plus robust and consistent image quality, is
perfect for long unattended printing jobs.
Here are some recommendations to help you deal with a long queue of printing jobs.
● If feasible, use brand-new long rolls of paper.
●
If you want to print on partly-used rolls, you can check the paper type and the remaining length
in the Embedded Web Server or in the front panel, to confirm that you have enough paper to
print all your jobs.
NOTE: Information on the remaining length is available only if you told the printer the length of
the roll when you loaded it, or if the printer read the length of the roll from the barcode printed on
it.
●
Load two rolls of paper suitable for your jobs. If the printer finishes one roll, it will automatically
switch to the other.
●
Check that you have paper wide enough to print all of your jobs. Any jobs that are too wide may
be put “on hold for paper” if the paper mismatch action is set to Put job on hold (see
Paper
mismatch action on page 21).
●
Check the ink levels remaining in your ink cartridges.
●
When you have submitted your print jobs, you can use the Embedded Web Server from a
remote location to monitor their status.
●
Drying time should be set to Optimal.
●
Select the Setup menu icon
, then Printing preferences > Paper options > Roll switching
options > Minimize roll changes or Use roll with less paper.
We recommend the following settings, depending on the paper type and what kind of prints you are
making.
