Discovered last night there are just a few of the hp-xxxx type commands which apply to the Deskjet 1000 j110a. I found them at the HPLIP site (I am an idiot I always forget to write down important stuff like URLs). Search on HPLIP and commands. Here is an example:
hp-align: Printer Cartridge Alignment Utility (ver. 5.0)
Cartridge alignment utility for HPLIP supported inkjet printers.
(Note: Not all printers require the use of this utility).
Usage: hp-align [DEVICE_URI|PRINTER_NAME] [MODE] [OPTIONS]
To specify a device-URI: -d<device-uri> or --device=<device-uri>
To specify a CUPS printer: -p<printer> or --printer=<printer>
Run in graphical UI mode: -u or --gui (Default)
Run in interactive mode: -i or --interactive
Use Qt4: --qt4 (Default)
Set the logging level: -l<level> or --logging=<level>
<level>: none, info*, error, warn, debug
Run in debug mode: -g (same as option: -ldebug)
This help information: -h or --help
The only other one tested which worked was hp-setup and it is about 3x longer with lots of options.
Yes, I have hp-toolbox.
Was dismayed that so few commands like linefeedcal, pqdiag, devicesettings, and printersettings do not apply to this printer.
Have been told that one can use PCL to effect modifications but it is uglier than than C# to work with. I used it eons ago and did download it but unlikely to use it.
I believe I have a way around the overprinting problem by using a script to make all pages of a document the effective first page. I gather U do not have the problem of it overprinting repeatedly pages from 2 onward. At least I will be able to use it if my script works.
