RE: HP82143A printing - two views of the same medal
In one document I found that on a buffer overflow the line is printed in the style of last used EOL (EOLL/EOLR).
So for the barcodes [e8] EOLR is used, for the staircase [e0] EOLL.
(07-17-2024 11:22 AM)ThomasF Wrote: The two 'barcode' lines are composed of exactly 44 columns, with the sequence [00,ab,bd,00] after the first and [e0] after the second. In both cases this results in a linefeed following the 'barcode'.
Drawing each barcode line is trigged by a buffer overflow. The byte sequence [00,ab,bd,00] is for the empty line between the barcodes.
So the [e0] code before the 'staircase' printing is the empty line between 2nd barcode and the 'staircase' and not for printing the 2nd barcode line.
(07-17-2024 11:22 AM)ThomasF Wrote: One thing I noticed is that the 'staircase' is printed by accumulating 45 bytes in total (3*15 columns).
This is correct follewd by the 2 bytes [00,d0]:
Code:
41BB 110 NCXQ 4422 [PROBY]
41BC 000 Data 0/@ ??
41BD 1D0 Data 464/· clr LCA, SCO, and DWM
So we have an overall size of 47 bytes for the 'staircase'.
(07-17-2024 11:22 AM)ThomasF Wrote: My question is who generates the linefeed after the staircase?
In my implementation the 44 byte buffer overflow of drawing the staircase
[01,01,01,02,02,02,04,04,04,08,08,08,10,10,10,20,20,20,40,40,40,80,80,80,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00]
with 44 byte in [e0] style. The buffer is empty then and reading the next three bytes [00,00,d0] send to the buffer of total 47, which are not printed at this time.
After this the user should test the mode switch and print key manually before the test prints the "TRY OUT ..." messages to test the intensity switch.
(07-17-2024 11:22 AM)ThomasF Wrote: The first [00] bytes after the first 'barcode' is probably printed on the line following the 'barcode', but is not visible on the paper, as I assume the [ab,bd] are treated as control characters.
The control codes [ab,bd] are responsible for the empty line between the two barcodes.

Line marked with "<-" are lines reading data from source und put the data into the 44 bytes character buffer. All lines marked with "Rowlength:" are generated by reading a byte from the 44 byte character buffer, evaluating the byte and show the number of columns in the row with the evaluated character number code and as character symbol.
Sometimes there are lines evaluted like this:
"Rowlength: 0, E8, è"
where the evaluated character [E8] is not in the character buffer. These are inserted EOL to advise the printing engine to draw a line left or right adjusted after a buffer overflow.
