Ploter jak na zdjęciu, jest sprawny, nie ma zasilacza.. Są pisaki, ale trochę przyschnięte. Opis do plotera jest po angielsku
Since this issue of Creative Computing is devoted largely to graphics, it seemed appropriate for our Print About Printers column
to become Plots About Plotters.We performed in-depth evaluations of two plotters, an eight-pen unit from Roland, and a single-pen unit from Enter Computer. The Roland unit is very similar
to their one-pen plotter and our comments apply to both units. Enter Computer recently introduced a six-pen plotter; we have included it in the chart and have some comments about it, but we
did not do a hands-on evaluation.Of the many plotters we have evaluated over the years, seven are still the current models. Question to readers: would you like a roundup of these and all
other currently available plotters in a future issue? More than just specifications, this would include our impressions and, in two cases, results from long-term use (sort of a 24,000-mile
evaluation). Roland X-Y PlottersRoland DG Corp. manufacturers two plotters, the DXY-800 (eight pens) and DXY-101 (one pen), specifically for use with microcomputers. Unique among small
plotters, the units can be used in either a horizontal or vertical position. We tested the DXY-800; however, most of our comments apply to both units. Out of the BoxPacked with the plotter
are eight colored pens, four pen holders (for standard nylon-tip pens), a stand (to hold the plotter in a vertical position), a power supply, and a manual. The only thing not included are
an interface cable and paper.The plotter measures 17" x 19.5" x 3"; an external power supply has two cables, one to the plotter and one to the outlet. In the horizontal position, the
plotter occupies 16" x 20" of desk space; using the heavy wire stand to put the plotter in a vertical position, the footprint shrinks to 10" x 20".The largest paper accepted is 420 x 297mm
(apparently a standard European size). The corresponding U.S. dimensions are 16.5" x 11.7"; the nearest standard size in the U.S. is 17" x 11".Although the manual seems to suggests that
plots can be drawn on the entire 420 x 297mm surface of the paper, this is not the case. The maximum area for plotting is 350 x 260mm (approx. 13.8" x 10.2"). The DXY-101 has a maximum x
dimension of 370mm (14.6").Two convenient magnetic strips hold the paper in place on the right and left. For large plots we would have appreciated additional strips for the top and bottom.
These are available as extra cost options, although we found that masking tape worked just fine.On the back of the plotter (assuming horizontal placement) are several connectors and
switches. The plotter can accept input through a parallel (Centronics) or serial RS-232 port. For serial operation, DIP switches are used to select the baud rate, parity, data bits, and
stop bits. We tried both interfaces and had no problems with either one.A push button off/on power switch is found on the back. In addition, at the top right of the plotter bed are two
other switches (Pen Up/Pen Down and Home) and two LEDs (Power On and Pen Up).Eight pen holders are at the top left of the plotter bed. Each one holds a Roland pen or a standard pen holder.
We tried a Pilot Razor Point pen with good results, although we can't see any reason not to use the included pens. Included colors are black, red, blue, green, pink, orange, purple, and
brown.Plotting is accomplished by means of a vertical bar which moves from right to left with a pen holder that moves up and down along the bar. Step size is 0.1mm (0.004") and repetitive
accuracy is 0.3mm (0.012"); in actual use, we found the plotter performed well within this limit, even with pen changes to other colors.Like other plotters, the DXY-800 is fairly noisy in
operation, particularly when making a series of small steps or pen up/pen down movements. Drawing CommandsThe plotter recognzes 20 commands. All commands are a single letter, although all
but one require one or more arguments. Home (H) is the only single letter command; it moves the pen to the 0.0 position.Two commands, Draw (pen down) and Move (pen up), cause the pen to
move to a position specified by x-y coordinates. As there is no scaling, these coordinates must be specified in integers representing 0.1mm (max. 3500 x 2600).The Increment command draws an
incremental distance from the last pen position; the Relative command performs the same operation with the pen up.The Line command draws solid or dashed lines with variable spacing. The
Axis command draws hash marks along an x or y axis.A group of four commands is used to draw alphanumeric characters and ten graph symbols in any of 15 different sizes (0.7 to 11.2mm high)
and four directions (0, 90, 180, 270 degrees).A group of four commands is used to draw circles and arcs in either absolute or relative locations. Arc angles are specified in degrees rather
than radians--a welcome feature. On the other hand, these commands can draw only circles (or portions) and not ellipses (which are possible on some other plotters). A related command is "K"
which draws division lines (like hash marks) in a circular pattern.Finally, the "T" command draws hatching (series of slanted lines for shading enclosed areas) within any defined
rectangular area.This is a comprehensive command set, although compared to a plotter such as the Houston Instruments DMP-29, the Roland DXY units are "missing" several useful commands.
Lacking, for example, are commands to reset the plotter, draw ellipses, draw different types of lines (other than solid and dashed), do scaling, change the pen speed, change the step size,
and connect points of an irregular curve. Even without these commands, the Roland plotters are quite versatile; nevertheless, certain types of plots will require more programming than they
would using a plotter with more built-in "intelligence." DocumentationThe Roland plotter comes with a 31-page manual which we rank as adequate--no more, no less. As far as interfacing, if
you are connecting the plotter to an Apple, TRS-80, or IBM PC with standard parallel interface, the instructions are complete. (Actually, they are fine for a parallel connection to any
computer, although only the above three are mentioned.) If you plan to use a serial interface, the manual provides the necessary information, although it is quite technical. IBM PC and
Apple cable connections are given, but no others.Seven pages of the manual are developed to a short description of each command along with a short program listing and a sample plot. Our
applause to Roland for including this detail, something sadly lacking in the documentation of nearly every other plotter we have evaluated.One-half a page is devoted to describing the
printer mode (using the plotter to print text); we found it inadequate. We also felt that the single page devoted to error indication and recovery could have been expanded. Good Price
PerformanceWhile the Roland DXY-800 does not have all the features of some other plotters, neither is it as expensive. Indeed, in the under $1000 price range, the DXY-800 is one of the few
plotters able to handle 11" x 17" paper and eight pens. The pen holders for standard pens are a nice plus as are the built-in parallel and serial interfaces. Furthermore, with the upright
stand, it has the smallest footprint of any unit that can handle 11" x 17" paper. We can't attest to its longevity, although it appears to be ruggedly built. The bottom line: for under
$1000, the Roland DXY-800 is an excellent buy.For business graphics, Roland offers a comprehensive software package which automatically produces line, bar, and pie charts according to your
specifications. Furthermore, it has the capability to read files from popular spreadsheet packages and graph the data. This package sells for $375. When it was first introduced in April,
Roland offered an attractive package price which included both the plotter and software; you might want to ask your dealer if this is still available.
