Conectați o imprimantă

Instalarea imprimantei se poate face în câțiva pași simpli. Imprimanta poate fi folosită pentru a imprima chitanțe, etichete, comenzi sau chiar rapoarte din diferite aplicații Odoo. În plus, acțiunile imprimantei pot fi atribuite ca acțiune pe un declanșator în timpul procesului de fabricație sau adăugate la un punct de control al calității sau un control al calității.

Atenționare

The only way to connect a printer directly to an Odoo database is through the use of an IoT system. Without an IoT system, printing can still occur, but it is managed through the printer itself, which is not the recommended process.

Conectare

IoT systems support printers connected through USB, network connection, or Bluetooth. Supported printers are detected automatically, and appear in the Devices list of the IoT app.

Notă

Printers can take up to two minutes to appear in the IoT app Devices list.

Link a printer

Link work orders to a printer

Work orders can be linked to printers, via a quality control point, to print labels for manufactured products.

In the Quality app, a device can be set up on a quality control point. To do so, go to the Quality ‣ Quality Control ‣ Control Points, and open the desired control point.

Important

A manufacturing operation and work order operation need to be attached to a quality control point before the Type field allows for the Print Label option to be selected.

From here, edit the control point by selecting the Type field, and selecting Print Label from the dropdown menu of options. Doing so reveals the Device field, where the attached device can be selected.

Imprimanta poate fi acum utilizată cu punctul de control al calității selectat. Când punctul de control al calității este atins în timpul procesului de fabricație, baza de date prezintă opțiunea de a imprima etichete pentru un anumit produs.

Sfat

Quality control points can also be accessed by navigating to IoT ‣ Devices, then selecting the device. Go to the Quality Control Points tab to add them to the device.

Notă

On a quality check form, the Type of check can also be set to Print Label.

Link reports to a printer

It is possible to link report types to a specific printer. To do so:

1. Go to IoT ‣ Devices and select the desired printer.

2. Go to the Printer Reports tab and click Add a line.

3. In the pop-up that opens, select the types of reports to be linked to the printer and click Select.

Sfat

Reports can also be configured by enabling the developer mode and going to Settings ‣ Technical ‣ Reports. Select the desired report from the list and set an IoT Device.

The first time a linked report is selected to print, a Select Printers pop-up window appears. Tick the checkbox next to the correct printer for the report, and click Print. At that point, the report is linked to the printer.

Clear device printer cache

After a printer is linked to print a report, the setting is saved in a browser’s cache. This means a user can have different devices saved in their cache for different reports, based on the device they use to access Odoo. It also means different users can have a report automatically printed from different printers, based on their preferences.

To unlink a report from a printer, navigate to IoT ‣ Configuration ‣ Reset Linked Printers. This generates a list of reports that are linked to a printer on the current device. Click the Unlink button next to each report to remove the link.

Important

This step only prevents the report from automatically printing to the listed printer from the current browser. The report is still linked on the device, under the Printer Reports tab.

Probleme potențiale

Imprimanta nu este detectată

If a printer does not appear in the devices list, go to the IoT box’s or Windows virtual IoT’s homepage, click Show in the Devices section, and make sure the printer is listed.

If the printer does not appear on the IoT system’s homepage, click Printer Server, then Administration, and Add Printer. If the printer is not in the list, it is likely not connected properly.

Imprimanta scoate text aleatoriu

Pentru majoritatea imprimantelor, driverul corect ar trebui detectat și selectat automat. Cu toate acestea, în unele cazuri, mecanismul de detectare automată ar putea să nu fie suficient și, dacă nu este găsit niciun driver, imprimanta poate imprima caractere aleatorii.

The solution is to manually select the corresponding driver. On the IoT system’s homepage, click Printer Server, then Printers, and select the printer in the list. In the Administration dropdown menu, click Modify Printer. Follow the steps and select the printer’s make and model.

Notă

Epson receipt printers and Zebra label printers do not need a driver to work. Make sure that no driver is selected for those printers.

The printer is detected but is not recognized correctly

If Odoo and the IoT system do not recognize the printer correctly, go to IoT ‣ Devices, click the device’s card to access its form, and set the Subtype field to the appropriate option: Receipt Printer, Label Printer, or Office Printer.

Caz special de configurare Epson

Most Epson printers support printing receipts in Odoo Point of Sale using the GS v 0 command. However, the following Epson printer models do not support this command:

• TM-U220

• TM-U230

• TM-P60

• TMP-P60II

To bypass this issue, you can configure the printer to use the ESC * command.

First, review Epson’s website for compatibility for both the GS v 0 and ESC * commands.

If the printer is incompatible with GS v 0 but supports ESC *, configure the IoT system to use the ESC * command as follows:

1. Access the IoT box’s or Windows virtual IoT’s homepage.

2. Click the Printer server button, then click Administration on the CUPS page.

3. Click Add Printer in the Printers section, select the printer, and click Continue.

   Sfat

   If the printer’s name is still uncertain, take the following steps:

   1. Take note of the listed printers on the CUPS page.

   2. Opriți imprimanta și reîmprospătați pagina.

   3. Compare the difference with the first list to see which printer disappeared.

   4. Porniți din nou imprimanta și reîmprospătați pagina.

   5. Verificați din nou lista pentru a vedea dacă imprimanta reapare.

   6. The printer that disappeared and reappears again on the listed printers is the name of the printer in question. It can be Unknown under Local printers.

4. On the Add Printer page, specify the printer’s Name using the following convention: <printer_name>__IMC_<param_1>_<param_2>_..._<param_n>__, where:

   • printer_name is the printer’s name. It can contain any character except _, /, #, or ` ` (space character).

   • IMC: Aceasta înseamnă Coloana mod imagine (numele simplificat pentru ESC *).

   • param_1: Aceasta reprezintă parametrul specific:

     • SCALE<X>: Scale of the picture (with the same aspect ratio). X should be an integer describing the scale percentage that should be used. For example, 100 is the original size, 50 is half the size, and 200 is twice the size.

     • LDV: Low Density Vertical (va fi setat la High Density Vertical dacă nu este specificat).

     • LDH: Low Density Horizontal (va fi setat la High Density Horizontal dacă nu este specificat).

     Notă

     • Density parameters might need to be configured in a particular way, depending on the printer model.

     • Refer to Epson’s ESC * documentation to determine if the printer requires these parameters to be set.

   Example

   Următoarele sunt exemple de formatare corectă și necorespunzătoare a numelui:

   Formatarea corectă a numelui:

   • EPSONTMm30II__IMC__

   • EPSON_TM_U220__IMC_LDV_LDH_SCALE80__

   Formatarea incorectă a numelui (acest lucru nu va împiedica imprimarea, dar este posibil ca rezultatul să nu aibă rezultatul imprimat așteptat):

   • EPSON TMm 30II: The name cannot contain spaces.

   • EPSONTMm30II: The name itself is correct, but it will not use ESC *.

   • EPSONTMm30II__IMC: This name is missing the end __.

   • EPSONTMm30II__IMC_XDV__: The parameter XDV does not match any existing parameters.

   • EPSONTMm30II__IMC_SCALE__: The parameter SCALE is missing the scale value.

5. Once the printer’s name has been defined using the appropriate naming convention, click Continue.

6. Set the Make value to Raw and the Model value to Raw Queue (en).

7. Click Add Printer. If everything was done correctly, the page should redirect to the Banners page.

8. Wait a few minutes for the IoT system to detect the printer and sync to Odoo’s server.

9. Access the POS settings and select your POS, or click the vertical ellipsis button (⋮) on a POS card and click Edit. Scroll down to the Connected Devices section, enable IoT Box, and select the printer in the Receipt Printer field. Click Save.

Notă

If the printer was set up incorrectly (e.g., it continues to print random text, or the printed receipt is too large or too small), it cannot be modified via the printer’s name in CUPS. Instead, configure a new printer from scratch with modified parameters, following the steps above.

Example

Următorul este un exemplu de proces de depanare pentru un model de imprimantă TM-U220B folosind comanda ESC *. Chitanța din imaginea de mai jos este un exemplu de chitanță care se imprimă corect datorită formatării corecte (teoretic):

Printing this receipt immediately without proper formatting will not work, as the TM-U220B printer model does not support the GS v 0 command. Instead, random characters will be printed:

To properly configure formatting for the Epson TM-U220B printer model, follow these steps:

1. After checking Epson’s website for compatibility with both the GS v 0 and ESC * commands, the TM-U220B printer is indeed incompatible with GS v 0 but supports ESC *.

   

2. When adding the printer, CUPS displays the list of available printers:

   

   In this case, the printer is connected via USB, so it is not part of the Discovered Network Printers. Instead, it is likely part of the Unknown selection under Local Printers. By unplugging the printer’s USB cable from the IoT system and refreshing the page, the Unknown printer disappears. By plugging it back in, the printer reappears.

3. For the naming convention, since the printer must print using the ESC * command, it is imperative to add __IMC.

   

   For this particular model (TM-U220) m should be equal to 0 or 1. While referencing the Description table on Epson’s ESC * website, the m values could be 0, 1, 32, or 33. So, in this case, the m value cannot be 32 or 33 (otherwise, random characters will be printed).

   The table includes the numeric values 32 and 33; they both occur if the Number of bits for vertical data is set to 24, i.e. it has a High Vertical Density. In the case of configuring the Epson TM-U220, the Low Vertical Density will need to be forced, as this printer model does not support High Vertical Density for this command ESC *.

   Pentru a adăuga o Low Vertical Density, adăugați parametrul LDV la convenția de denumire.

   

4. Click Continue to proceed. Next, set the Make value to Raw and the Model value to Raw Queue (en).

   

   However, when trying to print with the naming convention EpsonTMU220B__IMC_LDV__, the receipt is printed, but it is too large and outside the margin. To resolve this, add a new printer (and naming convention) with the SCALE<X> parameter to adapt to the receipt’s size.

   Aiici sunt câteva exemple:

   Convenția de denumire a imprimantei	EpsonTMU220B__IMC_LDV__	EpsonTMU220B__IMC_LDV_SCALE75__	EpsonTMU220B__IMC_LDV_LDH__	EpsonTMU220B__IMC_LDV_LDH_SCALE35__
