HP 2566C - Manual (Page 69)

Remote Character Set
The character sets shown in your self-test printout may also be selected
remotely if performed under program control. Character set selection
commands override the Operator Control Panel configuration setting
(except under power-on or reset conditions). When taken “off-line,”
the printer remains in the character set last commanded. See the
HP256X Printer Family Technical Reference Manual, 02564-90905, for
information on remote character set selection.
Standard ASCII SHIFT-IN and SHIFT-OUT codes may be used to select
primary and secondary character sets. SHIFT-OUT selects the secondary
set and SHIFT-IN returns the printer to the primary set. Any number
of character sets may be used within one print line if they are the same
pitch. Additionally, bar codes and line draw can be printed on the same
line as 10 character-per-inch (cpi) character sets. (Compressed character
sets and the double-high/double-wide character set cannot be printed on
the same line with each other or with 10 cpi text.)
Select Page Length
Representation:
FUNCTION 7
Page length can be selected in either lines-per-page or in ^ inch
increments. Refer to “Adjusting Forms Length” on page 3-25 for
instructions on how to set the CONFIGURATION mode.
Disconnect Modem:
FUNCTION 50
If a serial interface is installed in the printer and is connected to a
modem, it is possible to disconnect the modem from the printer’s
Operator Control Panel. Setting function 50 to parameter “1” and then
pressing
( enter !
makes the Data Terminal Ready line to go to the
“OFF” state for two seconds. If the modem Data Terminal Ready line is
connected, this action should disconnect (hang-up) the modem.
Difficult Forms Mode:
FUNCTION 51
Some complex multi-part forms such as statement mailers or invoices
may result in a loss of the Top of Form position. If this problem occurs,
the printer can be placed in a low speed, high torque mode by accessing
function 51 of the CONFIGURATION mode and selecting parameter
“1.” Since this will affect throughput, make sure function 51 is set back
to “0” when the high torque mode is not required.
Horizontal Graphics
Density Selection:
FUNCTION 52
Horizontal graphics density (60 or 70 dots per inch) is selected via
function 52. There is not a parameter “1” or “0” for this function. Only
60 or 70 shows up in the display window. Programmatically setting
the density overrides the operator control panel setting except under
power-on or reset conditions. Default value is 70 dots-per-inch (dpi).
